Double Row Deep Groove Ball Bearing – 4308 ATN9

The 4308 ATN9 Double Row Deep Groove Ball Bearing is designed for robust operation with minimal maintenance requirements. This bearing provides high-load capacity and can handle radial and axial loads in both directions, making it ideal for demanding applications. Its double-row configuration allows for a higher load-carrying capacity compared to single-row bearings of the same size.

With a basic dynamic load rating of 55.9 kN and a basic static load rating of 45 kN, this bearing can accommodate both high axial and radial loads while operating at high speeds of up to 12,000 r/min (reference speed). Additionally, it has a limiting speed of 6,700 r/min. The bearing is made from durable bearing steel and features a non-metallic cage for smooth operation. It is non-sealed and unlubricated, allowing flexibility for customized lubrication based on your specific requirements.
