SKF deep groove ball bearing 6328 zz tool bearing koyo fittings automotive bearing bearings

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. 

They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. 

The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. 

Integral sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed  makes radial and axial loads in both directions, so it requires little maintenance.
