Machinery Lubricants

Featured products

Machinery lubricants are specially formulated oils and greases used to reduce friction, wear, heat, and corrosion between the moving parts of industrial machinery. They form a protective film between contacting surfaces to help machinery operate smoothly and reliably under different loads, speeds, temperatures, and operating conditions.

Common types of machinery lubricants include industrial gear oils, hydraulic fluids, compressor oils, turbine oils, circulating oils, bearing greases, and speciality lubricants. Depending on the application, formulations may contain additives to provide anti-wear protection, oxidation resistance, corrosion control, foam suppression, or extreme-pressure performance.

Lithium Grease

Lithium Grease is a general-purpose lubricating grease made from high-quality base oil and lithium soap thickener, with anti-oxidation, anti-rust and anti-wear additives. It provides good lubrication, water resistance, mechanical stability and adhesion for bearings, hubs, joints and moving parts under normal temperature and medium load conditions.

Extreme Pressure Lithium Grease

Extreme Pressure Lithium Grease is a high-performance lubricating grease fortified with extreme pressure additives. It provides superior anti-wear, load-bearing, water resistance and anti-rust protection for heavy-duty bearings, gears and moving parts under shock load, high pressure and harsh working conditions.

High Temperature Grease

High Temperature Grease is a high-performance lubricating grease specially designed for high-temperature operating conditions. It features excellent high-temperature resistance, anti-oxidation, low oil separation and long service life, providing stable lubrication for bearings and moving parts under continuous high-temperature environments.

Low Temperature Grease

Low Temperature Grease is a special lubricating grease with excellent lowtemperature fluidity and low torque. It ensures smooth startup and stable lubrication for bearings and moving parts in cold environments.

White Oil

White Oil is a colorless, odorless, non-toxic refined mineral oil with high purity, good stability, low viscosity and excellent lubricity. It is widely used in textile, plastic, cosmetic, food machinery and general industrial lubrication fields.

Transformer Oil

Specially formulated for various power transformers, distribution transformers and electrical equipment with oil-immersed insulation structure, it is suitable for insulation and heat dissipation of iron cores, windings and other key components of transformers, providing reliable insulation protection, efficient heat dissipation and anti-aging performance under long-term continuous operation and different temperature working conditions.

Industrial Gear Oil

Industrial gear oil is a lubricant specifically engineered for industrial enclosed and open gearboxes, including reducers and speed increasers. Formulated with high-performance base stocks and advanced extreme-pressure anti-wear additives, it generates a robust lubricating film to minimize gear flank wear, resist scuffing, dissipate heat, prevent rust and corrosion, and prolong gear service life. In contrast to automotive gear oils, industrial gear oil prioritizes stability under heavy-duty loading, extended service intervals, high-temperature operation, and water-contaminated environments. In compliance with GB/T 7631.7 (equivalent to ISO 6743), enclosed industrial gear oils are clearly categorized under the L‑CK series.

Injection Molding Machine Oil

Specially formulated for hydraulic systems of injection molding machines, it is suitable for various plastic injection molding equipment of different tonnages, providing excellent anti-wear protection and stable hydraulic transmission under high pressure, high speed and long-term continuous operation conditions.

AW Hydraulic Oil

Anti-wear Hydraulic Oil is a core category of special lubricants for hydraulic systems. Its key functions include transmitting hydraulic power, lubricating hydraulic components, resisting wear and reducing friction, preventing rust and corrosion, and cooling and dissipating heat. By incorporating high-efficiency anti-wear additives (such as zinc-based and ashless types), it solves wear problems of precision parts including hydraulic pumps, valves and cylinders. It is suitable for medium and high-pressure hydraulic systems and is the most widely used type of hydraulic oil in industries such as manufacturing, construction machinery, metallurgy and mining.

Air Compressor Oil

Air compressor oil is a special lubricant designed for air compressors. Its core functions include lubrication, cooling, sealing, rust prevention and cleaning. It is suitable for the high-pressure, high-temperature and high-load operating environment of air compressors. Its performance directly affects the operating efficiency, service life and air discharge quality of air compressors. Selection should be tailored according to the type of air compressor and working conditions.

Applications of Machinery Lubricants

  1. Industrial Gears and Gearboxes

Gear oils are used to lubricate gears, bearings, and other transmission components. This helps to reduce friction and wear when operating under high loads or continuously.

  1. Hydraulic machinery

Hydraulic fluids provide lubrication and transfer power through hydraulic systems, supporting the operation of pumps, valves, cylinders and other components.

  1. Compressors and pumps

Specialised lubricants protect the bearings, gears, pistons and other moving components in air and gas compressors, as well as industrial pumps.

  1. Manufacturing and processing equipment

Machinery lubricants are widely used in production machinery, conveyors, machine tools, extrusion equipment and other industrial systems, supporting stable operation and extending component life.

  1. Power generation and heavy equipment

Turbine oils, gear oils, and greases are used in turbines, generators, mining equipment, and construction machinery operating under demanding conditions.

Machinery Lubricants FAQs

  1. What are machinery lubricants used for?

They reduce friction, wear, heat, and corrosion between the moving parts of industrial machinery. They help gears, bearings, hydraulic systems, compressors and other mechanical parts to operate smoothly and reliably.

  1. What are the main types of machinery lubricant?

Common types include gear oils, hydraulic fluids, compressor oils, turbine oils, circulating oils, bearing greases, and speciality lubricants. Each formulation is designed for specific types of machinery and operating conditions.

  1. How do I choose the right lubricant for my machinery?

Consider the equipment manufacturer’s specifications, lubricant viscosity, operating temperature, load, speed, pressure, environmental conditions, and component materials. Compatibility with seals and existing lubricants should also be checked before switching products.

  1. How often should machinery lubricants be replaced?

This depends on the type of lubricant, the design of the equipment, the operating conditions, the level of contamination, and the manufacturer’s maintenance recommendations. Oil analysis and regular condition monitoring can help determine whether a lubricant remains suitable for continued use.

  1. Can the same lubricant be used for different machines?

Not always. Different machines and components may require specific viscosity grades, additive systems, or performance characteristics, so a lubricant should only be used if it meets the requirements of the equipment manufacturer.

  1. What happens if machinery is inadequately lubricated?

Insufficient or unsuitable lubrication can increase friction, wear, heat generation, corrosion, and component damage. In severe cases, poor lubrication can lead to equipment failure and unplanned downtime.
