Deep groove ball bearing with snap ring and integral sealing
Single row deep groove ball bearing, with snap ring groove and shields on both sides, 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 other bearing types. The snap ring, fitted in an annular groove in the outer ring, facilitates axial location of the bearings within their housings. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.
- Snap ring facilitates axial location within housing
- Integral sealing prolongs bearing service life
