High-end bearing industry
China has become the world’s largest producer and consumer of bearings; however, for many years, bearing lubrication‑grease technology has been dominated by foreign brands, hindering the industry’s drive toward self‑reliance and security. Since its inception, Derunbao has focused on this critical field, leveraging more than a decade of technological accumulation and groundbreaking innovation to successfully achieve import substitution for mid‑to‑high‑end lubrication products, helping Chinese equipment‑manufacturing companies reduce costs, boost efficiency, and expand into international markets.
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 bearing 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 especially critical in continuous‑production settings and applications demanding high reliability.
