Deep Groove Ball Bearings FAG 62306 -2RSR

The FAG 62306 -2RSR deep groove ball bearing, measuring 30x72x27 mm and featuring seals on both sides, provides protection against radial loads.

The 62306 -2RSR deep groove ball bearing is a single-row radial ball bearing made from standard rolling bearing steel 100Cr6, with dimensions of 30 mm bore, 72 mm outer diameter and 27 mm width. FAG manufactures this version with a sheet steel cage and standard radial clearance in tolerance class P0/PN or ABEC 1. Thanks to the seals on both sides, the component protects the rolling element chamber from the ingress of dirt and moisture. The wider special design is primarily intended to provide radial load-carrying capacity in compact shaft mounting arrangements.

What is the 62306-2RSR deep groove ball bearing suitable for in operation?

This deep-groove ball bearing is designed for bearing arrangements subject to predominantly radial loads and moderate axial forces in both directions. The 2RSR sealing lips, which seal on both sides, prove their worth in dusty or damp operating environments. Compared with narrower standard bearings, the 27 mm width provides an increased contact area on the shaft. The permissible temperature range extends from -20 to +100 degrees Celsius and meets the requirements of common industrial applications.

What are the key features of the double-sided 2RSR seal on this FAG bearing?

The designation 2RSR stands for double-sided, sliding contact seals. These sealing lips lie directly against the inner ring and help to keep out particles and splash water. At the same time, they help to retain the lubricant within the bearing housing. The standard radial bearing clearance is designed for standard shaft and housing fits. Before installation, it is advisable to check the mounting dimensions of 30 mm on the shaft and 72 mm in the housing bore.
