Ebmotrix Bearings
1 / 5
The VE140A01 four-point contact ball slewing bearing is engineered for high-performance applications including rotary conveyors, welding manipulators, cranes, and excavators. Made from high-grade materials like 42CrMo and GCr15, these bearings support customized inner ring sizes from 200mm to 5000mm.
Manufacturing Excellence: Our raceways are quenched using medium frequency processes, achieving a hardness of HRC55-62 with a depth of no less than 3mm. This eliminates quenching stress and reduces the risk of cracking, ensuring long-term durability in heavy-duty industrial environments.
