Robotics industry
Robot lubricating greases are essential consumables for robotic drive systems. Their applications span critical components such as RV reducers, harmonic reducers, joint bearings, linear guides, ball screws, and high-speed motor bearings. Operating under severe conditions—high loads, frequent start–stop cycles, fretting wear, and constrained sealing—these greases must meet extremely stringent requirements for service life, extreme-pressure and anti-wear performance, low-temperature start-up, and high-temperature stability. Any failure in lubrication can lead to reduced robot accuracy, abnormal vibration and noise, premature reducer wear, or even complete system shutdown, resulting in substantial maintenance costs and production‑line downtime—issues that are particularly acute in continuous‑production environments such as semiconductor, automotive, and 3C manufacturing.

High-end bearing industry
Bearing lubricating grease is a critical consumable for the operation of bearing systems. Its applications span a wide range of bearings, including deep‑groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, spherical roller bearings, and thrust bearings. Operating under demanding conditions—high rotational speeds, heavy loads, extreme temperatures, humid environments, dusty atmospheres, and severe shock and vibration—lubricating greases must meet exceptionally stringent requirements for extreme‑pressure and anti‑wear performance, oxidation stability, corrosion resistance, low‑temperature startability, and long‑term service life. Any failure in lubrication can lead to overheating, accelerated wear, increased vibration, excessive noise, or even seizure, resulting in costly equipment downtime, soaring maintenance expenses, and production line disruptions—consequences that are particularly critical in continuous‑production settings and applications demanding high reliability.

Automotive parts industry
Automotive lubricants and greases are critical consumables essential for the proper operation of a vehicle’s core systems. Their applications span key components such as wheel hub bearings, constant-velocity joints, transmission gears, steering gearboxes, brake calipers, sunroof guide rails, and seat‑adjustment mechanisms. These lubricants must endure harsh operating conditions—high rotational speeds, heavy loads, a wide temperature range (from cold‑start at –40°C to high‑temperature braking), impact and vibration, exposure to mud and water, and extended periods of maintenance‑free service—placing extremely stringent demands on extreme‑pressure and anti‑wear performance, oxidation stability, corrosion resistance, low‑temperature fluidity, rubber compatibility, and long‑term reliability. Any failure in lubrication can lead to abnormal noises and bearing burnout in wheel hubs, wear and fracture of constant‑velocity joints, jerky gear shifts in transmissions, steering binding, brake drag, or even serious traffic accidents, resulting in substantial repair costs and significant safety risks—issues that are especially critical in the context of the trend toward long‑life, maintenance‑free designs in new‑energy vehicles.

Steel industry
Metallurgical lubricants and greases are the “lifeblood” of continuously operating steel‑making equipment. Their applications span critical components such as rolling mill bearings, dry‑oil lubrication systems, centralized lubrication systems, open gears, wire ropes, and the sector rolls of continuous casting machines. Operating under extreme conditions—prolonged exposure to high‑temperature radiation, heavy‑load impacts, water‑borne erosion, ingress of iron oxide scale, and continuous, uninterrupted production—these lubricants demand exceptional performance in extreme‑pressure and anti‑wear properties, high‑temperature stability, water resistance, corrosion protection, pumpability, and long‑term reliability. Any lubrication failure can result in bearing seizure, roller‑line blockages, excessive gear wear, or even unplanned shutdowns of the entire production line, leading to economic losses of hundreds of thousands of yuan per minute and posing serious safety risks—factors that make these lubricants especially critical in continuous, automated manufacturing environments.
Metallurgy
Heavy industry
Lubricating greases for heavy‑duty machinery are the lifeblood of reliable equipment operation. Their applications span critical components such as pin joints in work devices, slewing bearings, track‑drive systems, gearbox gears, boom bearings on concrete pump trucks, wheel hub bearings on mining trucks, and hydraulic breakers. These greases must endure extreme operating conditions—severe heavy‑load impacts, low‑speed oscillation, intrusion of mud and sand, a wide temperature range (from frigid −30°C to high‑temperature friction), and continuous outdoor service—placing exceptionally high demands on extreme‑pressure and anti‑wear performance, water resistance, impact resistance, adhesion, pumpability, and corrosion protection. Any lubrication failure can lead to abnormal wear of pin joints, seizure of slewing bearings, track fractures, gearbox burnout, or even complete machine downtime, resulting in repair costs running into hundreds of thousands of yuan and delays in project schedules—issues that are particularly acute in continuous‑operation environments such as mines, infrastructure projects, and ports.

Power tools industry
Lubricating greases for power tools are essential consumables in their transmission and motion systems. Their applications span critical components such as high-speed gears, impact mechanisms, bearings, commutators, and the lubrication of plastic and metal structural parts. Operating under severe conditions—high rotational speeds, heavy impact loads, a wide temperature range (from low‑temperature start-up to high‑temperature operation), and exposure to dust and moisture—these greases must meet exceptionally stringent requirements for anti‑wear and extreme‑pressure performance, low‑temperature starting characteristics, high‑temperature durability, material compatibility, and noise reduction. Any failure in lubrication can lead to unstable tool speed, reduced impact force, accelerated commutator wear, excessive gear wear, or even complete equipment failure, resulting in increased maintenance costs and a degraded user experience—factors that are especially critical in continuous production and professional‑grade applications.

Wind power industry
Wind‑turbine lubricants are the “lifeblood” ensuring the long‑term, reliable operation of wind‑energy systems. Their applications span critical drivetrain components, including low‑speed, heavy‑load main‑shaft bearings, high‑precision yaw and pitch bearings, high‑speed gearboxes, and generator bearings. These greases must endure harsh operating conditions—such as high altitude, low temperatures, humid‑hot environments, salt‑spray corrosion, sand erosion, and extended maintenance‑free service intervals (3–5 years)—placing exceptionally stringent demands on extreme‑pressure and anti‑wear performance, low‑temperature startability, resistance to fretting wear, corrosion protection, and service‑life stability. Any lubrication failure can lead to accelerated bearing wear, pitting in gearboxes, yaw‑system seizure, or even complete unit shutdown, resulting in multimillion‑dollar repair costs and lost revenue from power generation—issues that are particularly acute in offshore wind farms and with large‑megawatt turbines.
