Deep Groove Ball Bearings SKF 6308 -2RS1

The 6308-2RS1 deep groove ball bearing from SKF combines a 40 mm bore and a 90 mm outer diameter with seals that seal on both sides.

The 6308-2RS1 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 bearing steel. This SKF Wälzlager design primarily absorbs radial forces and also supports axial loads in both directions. Thanks to the factory-fitted seals, the design protects the bearing interior from dirt particles. Maintenance engineers and designers use this versatile unit in numerous rotating shaft arrangements in industrial machinery.

What is the 6308-2RS1 deep groove ball bearing suitable for in practice?

This rolling bearing is used wherever shafts with a 40 mm diameter need to be supported under medium to high loads. It is designed for bearing locations subject to combined loads in dusty or damp environments. The integrated seal helps to retain the lubricant within the bearing housing and to keep out moisture and particles. Thanks to its robust sheet steel cage, the bearing performs reliably under continuous speeds and varying load directions in continuous operation.

What is the advantage of the double-sided 2RS1 seal on this bearing?

The suffix 2RS1 denotes abutting sealing lips on both sides. Compared with open designs, this contact protection reduces maintenance requirements, as the interior remains shielded from environmental influences. When selecting the bearing, you should take into account the standard radial bearing clearance and tolerance class P0 (ABEC 1). The component is designed for an operating temperature range of -20 to +120 degrees.
