Open gear lubrication solutions used in domestic mining and heavy industry have gone through four generations of iteration. Each new generation was developed to solve the core pain points of its predecessor, adapting to more demanding and more economical operating conditions. At a glance Three lubricant generations — each evolved to solve the last one's flaws. Solvent-based lubricant is the best-in-class solution for large, heavy-duty mills. NATCO offers 4 products — from top-tier heavy-duty to economical universal. 1. Open Gear Lubricant Evolution: Three Generations & Best-in-Class Solution 1.1 First Generation — Hot-Melt Asphalt Lubricant (Phased Out) The earliest open gear lubricant product in the industry, with relatively good basic lubrication, adhesion, and anti-wear performance — but two fatal flaws led to its near-complete phase-out. Why it was phased out: Unsafe — contains benzo[a]pyrene, a carcinogen that harms operator health and fails environmental compliance. Hard to use — cools into a hard, brittle solid; oil film frequently ruptures during gear operation. 1.2 Second Generation — Open Gear Grease (Early European Solution, Being Phased Out) First introduced by European companies: base oil + thickener + functional additives. The thickener locks oil in place to prevent grease from falling off. Early on, it was promoted by Fuchs, Klüber, and other international majors. The core problem: centrifugal force from high-speed gear rotation easily throws the grease out, preventing formation of a stable oil film. Spray interval: only 2–5 minutes (per Metso guidelines) Consequence: extremely high oil consumption, high operating costs, frequent manual maintenance Status: being phased out by the industry Many low-end products on the domestic market use 5000 cSt low-viscosity base oil with small amounts of thickener, graphite, and MoS₂. These have thin films, poor elasticity, fast base-oil loss, and rely only on solid particles — directly causing accelerated gear wear. 1.3 Third Generation — High-Viscosity Pure Oil Lubricant (Mainstream European Solution) Developed by European manufacturers to solve grease's high-consumption problem. Mainly uses Group III hydrocracked base oils — better cost-effectiveness than high-end Group IV PAO synthetics. Common viscosity grades: 10,000–46,000 cSt. Trade-off: higher viscosity → harder to pump at low temperatures. Most products need heating in 10–20°C environments. Some brands blend in low-viscosity mineral oil to improve cold flow — but this sacrifices some EP/anti-wear and film stability. Supply interval: 5–15 minutes Consumable usage: significantly reduced Overall protection: limited 1.4 Best-in-Class Solution — Solvent-Based High-Viscosity Lubricant (Mainstream American Solution) The optimal solution for large, heavy-duty open gears today. Combines ultra-high-viscosity base oil with non-toxic, non-chlorinated solvents to solve the pumpability challenge. Lowest pumpable temperature reaches -10°C, balancing cold workability with heavy-duty protection. Two sub-types exist. Type A — Asphalt-Based Solvent Lubricant A safety-upgraded version of hot-melt asphalt: hydro-refined asphalt treated to be non-toxic, TCLP-compliant, eliminating traditional asphalt's cancer risk (reference: Shen Jin'an, "Asphalt and Asphalt Mixture Road Performance"). Base viscosity exceeds 100,000 cSt. Biggest advantage — extreme fault tolerance: when the lubrication system fails or oil supply is interrupted, the high-strength oil film remains adhered to the tooth surface for an extended period. A domestic Huaneng power plant once achieved 7 days of zero gear surface damage despite complete oil supply interruption. Drawback: weak waste-oil fluidity, residual oil accumulation at gear root, slightly more cumbersome cleaning. Type B — Non-Asphalt-Based Solvent Lubricant Developed to solve asphalt-based products' residual-oil accumulation and cleaning issues. Uses synthetic polymer + high-viscosity mineral oil base, also providing 100,000+ cSt base viscosity and -10°C pumpability. Better fluidity and cleanliness, easier on-site maintenance. Oil film elasticity and ultimate adhesion are slightly lower than asphalt-based; EP/anti-wear is essentially on par. Industry Authoritative Conclusion Per Metso's official standards, solvent-based lubricants achieve a 15–20 minute supply interval — the most mature solution with the lowest consumable usage, suited to large heavy-duty mills. Other oils claiming 15–20 minute intervals only apply to small/medium light-load equipment. Solvent-based lubricants must fully evaporate before forming a high-strength protective film — this is the industry standard application procedure. 2.

How to Build an Industrial Lubricants Business

Build a more stable business approach through market focus, customer understanding, technical support, and the right partnerships

Industrial LubricantsBusiness Strategy

## How to Build an Industrial Lubricants Business Building an industrial lubricants business may look like selling products, but in practice it is closer to building a long-term industrial service business. Customers rarely switch products because of a price list alone. What they care about more is whether their equipment runs reliably, maintenance becomes easier, and someone can continue supporting them when problems arise. So if you want to make this business work, the key is usually not just "finding customers." It is deciding where to enter the market, how to build trust, and how to organize product capability, technical support, and ongoing service. ## First: be clear about where you want to enter Industrial lubricants cover many industries, equipment types, and operating conditions. Instead of trying to cover too many sectors and product lines at once, a more practical approach is to start with a clearer point of entry. You can begin by asking a few questions: - Which industries or equipment scenarios are closest to your existing resources? - Are the contacts you reach more on the procurement side, the equipment management side, or the maintenance side? - Are you better positioned to start with grease, gear oil, hydraulic oil, or products for specific operating conditions? - Is your advantage price, responsiveness, industry relationships, or application-level communication? The clearer your entry point is, the easier the early-stage business development becomes. Industrial lubricants do not behave like a fast-moving consumer product. Customers usually care much more about application fit and operating results. If your direction is too broad at the beginning, product preparation, technical communication, and customer follow-up all become heavier. ## Second: understand what customers are really buying Many people entering this industry for the first time assume industrial lubricants are as simple as "the customer asks for a grade, and I quote that grade." In reality, industrial customers are not just buying the lubricant itself. What they usually care about is: - Whether the product truly fits the current equipment and operating conditions - Whether it can reduce wear, leakage, downtime, or frequent maintenance - Whether it remains stable under heat, heavy load, moisture, dust, or other harsh conditions - Whether someone will follow through during trial and changeover - Whether support is available quickly when abnormalities appear In other words, customers are buying a more stable operating outcome, not just a product name. That is why the further you go in this business, the less it feels like simple trading and the more it resembles a long-term service built around equipment reliability. ## Third: do not fall into pure price competition too early Price matters, but competing on price alone narrows the business very quickly. Once you position yourself as "whoever is cheaper wins," it becomes hard for customers to see any higher value in what you offer. A more effective approach is usually to focus the conversation on questions like these: - What is the customer’s main problem right now? - Why is the current product not performing well enough? - If the customer changes the solution, which result do they most want to improve? - Beyond purchase price, have they considered maintenance frequency, downtime losses, lubricant consumption, and cleaning costs? When you can shift the discussion from "unit price" to "total cost of use" and "actual operating results," customers are much more likely to evaluate your proposal seriously. That is often the dividing line between shallow business and business that can truly grow. ## Fourth: make the early-stage assessment as detailed as possible One of the most common problems in industrial lubricant projects is not a lack of demand. It is that the early-stage assessment is too rough, which later leads to poor recommendations, unsuccessful trials, or a loss of customer confidence. At the initial stage, you should try to clarify at least the following: - Equipment type and key lubrication points - Current product and the reason for considering a change - Temperature, load, speed, moisture, dust, and other operating conditions - Relubrication or oil change intervals - Maintenance habits on site and common abnormalities - The issue the customer most wants to improve first The clearer this information is, the more grounded your later product judgment will be. On the other hand, if you recommend a product based only on a vague request, the probability of failure rises significantly. ## Fifth: move from "selling oil" to "building solutions" A more competitive business is not one that sells a product once. It is one that makes customers willing to keep using, expand usage, and continue the relationship. To do that, you cannot stop at selling a drum of oil or a single grade. You need to gradually build solution capability. That solution capability usually includes: - Understanding the customer’s equipment and operating conditions - Explaining why a certain product category is recommended - Supporting the customer through trial and changeover - Tracking usage feedback and adjusting in time - Turning a single product opportunity into a long-term customer relationship When you have that capability, customers are much more likely to treat you as a long-term partner rather than a temporary supplier. ## Sixth: you do not have to carry all the technical burden alone Many people hesitate to enter the industrial lubricants business because they feel they are not technical enough yet. That concern is understandable, but in reality, business development people do not need to master every technical detail at the very beginning. What matters more is whether you can understand the customer’s needs accurately and whether you have reliable resources behind you to support later judgment. In many cases, industrial lubricant business is not completed by one person alone. It is the result of coordination across sales, product, application, and service. That is also why the kind of partner you choose directly affects how efficiently you can move the business forward. ## The right partner affects whether the business can become stable Once you start working with real customers, you quickly realize that many questions cannot be solved by sales activity alone. Customers will ask why a product is suitable, what it can improve, what they need to watch during use, and how to handle abnormal conditions. If there is no stable technical and application support behind the front-end team, it becomes very difficult. That is why a partner usually needs to meet at least a few conditions: - A product line that covers the main scenarios you want to enter - Enough understanding of application and operating conditions, not just a product number - The ability to support trials, changeovers, and problem handling - Relatively stable communication, supply, and follow-up service - A willingness to build long-term customer relationships together, not just complete one transaction ## Why some partners include NATCO in their consideration set In that context, some partners include NATCO in their shortlist not simply because of the brand name, but because they want more complete business support. For many channel partners, what really matters is not just getting a quotation. It is whether someone can work with them through early-stage assessment, product screening, customer communication, trial follow-up, and problem analysis. NATCO’s value is reflected more in that coordination than in supply alone. In practice, common value from working with a partner like NATCO includes: - Helping narrow product judgment early in a project - Providing clearer application logic in customer discussions - Offering more stable support during trial and changeover - Assisting in analyzing causes and adjusting direction when problems appear - Helping channel partners turn a single transaction into a long-term relationship If your strength lies in market development, customer relationships, and local service, and you do not want to carry every technical detail alone, this kind of cooperation is usually much more practical. ## If you want to learn more about NATCO, start with these pages If you want to evaluate whether NATCO fits your business direction, these pages are a practical place to start: - [View NATCO product categories](/products/all) - [Explore NATCO rail friction management applications](/rail) - [See partnership and channel information](/distributor) - [Contact NATCO to discuss business needs](/contact) These pages can help you judge whether the product line, application coverage, and partnership model match your current direction. ## Final thought: this business is built on rhythm, not slogans Industrial lubricants are not the kind of business that succeeds through short-term bursts alone. It demands judgment, customer understanding, steady follow-up, and the ability to organize support behind the scenes. If you can choose the right entry point, gradually build stronger application judgment, customer communication, and solution capability, and secure the right support resources behind you, the business becomes much easier to stabilize and far more likely to last. From that perspective, there is no single answer to "how to build an industrial lubricants business." But one path is often more effective than the others: understand the customer first, build solution capability second, and then use the right products, support, and partnership model to move each project forward steadily.
