6018-2Z Single Row Deep Groove Ball Bearing 90x140x24mm For Gearboxes Compressors Transmission Systems

6018-2Z is a standard single row deep groove ball bearing fitted with double-sided metal dust shields, overall dimensions 90×140×24 mm. Produced from high wear-resistant GCr15 bearing steel and equipped with stamped steel cage, it delivers stable precision performance.

The 2Z metal cover design blocks dust and solid particles from entering the bearing interior effectively. Its deep groove raceway can withstand radial loads as well as light axial loads in both directions. With low friction, quiet operation and stable high-speed performance, this bearing is widely used for heavy-duty continuous rotating machinery under dry and dusty working conditions.
