Deep Groove Ball Bearings FAG 62307 -2RSR

The FAG 62307 -2RSR deep-groove ball bearing, with sliding seals on both sides and dimensions of 35 x 80 x 31 mm, protects the bearing housing from contamination.

This single-row deep groove ball bearing 62307 -2RSR from FAG is made from 100Cr6 rolling bearing steel. Thanks to its wide 31 mm design, the bearing reliably absorbs radial forces as well as axial forces on both sides. The contact seals fitted on both sides help to keep dirt particles and moisture out of the bearing interior. With a sheet steel cage and standard radial clearance, this ball bearing meets a wide range of requirements for rotating shafts.

What is the 62307 -2RSR deep groove ball bearing suitable for?

Design engineers and maintenance personnel primarily use the 62307 -2RSR deep groove ball bearing where the installation space requires an increased bearing width. This design is suitable for bearing arrangements subject primarily to radial loads, where moderate axial forces are also present. Typical applications include shaft mountings and industrial gearboxes where dusty or damp environmental conditions require a sliding seal for the bearing housing.

What are the distinctive features of the 2RSR seal on this bearing?

The 2RSR design features abiding rubber sealing lips mounted on both sides. These abiding sealing discs lie directly against the inner ring and keep dirt and splash water away from the raceway system. At the same time, the lubricant remains within the bearing chamber. For the temperature range from -20 to +100 degrees, this design offers a practical solution. As the sealing lips rest against the inner ring, friction is generated compared with open bearings; this should be taken into account when determining the rotational speed.
