Deep Groove Ball Bearings SKF 6008 -2RS1

The SKF 6008-2RS1 deep groove ball bearing, measuring 40x68x15 mm and featuring seals on both sides, offers protection against dirt particles.

The 6008 -2RS1 deep groove ball bearing is a single-row radial ball bearing from SKF’s Explorer performance class. Manufactured from standard 100Cr6 rolling bearing steel, this bearing accommodates radial forces as well as axial loads in both directions. A robust sheet steel cage guides the rolling elements evenly in the deep raceways. Thanks to the standard radial clearance, the bearing is suitable for standard operating conditions without excessive thermal expansion. The design, which has no groove or flange on the outer ring, allows for direct installation in cylindrical housing bores.

For which operating conditions is the 6008-2RS1 deep-groove ball bearing suitable?

This design is primarily used in applications involving combined radial and axial loads, as well as moderate operating temperatures. The sealing discs, which rub against both sides, ensure that lubricant remains inside whilst making it difficult for dust and moisture to penetrate. The bearing is designed for a temperature range of -20 to +120 degrees Celsius. Thanks to its manufacture to tolerance class P6 (ABEC 3), the shaft runs with dimensional accuracy and low vibration, which helps to reduce noise levels during operation.

What are the advantages of the 2RS1 seal and tolerance class P6?

The 2RS1 seal’s sealing lips rest against the inner ring under slight radial pressure, which reduces maintenance requirements compared with open designs. Compared with standard tolerance, class P6 has tighter roundness and width tolerances. During assembly, it is recommended to align the bearing with clean mounting shoulders on the shaft (40 mm in diameter) and in the housing seat (68 mm outer diameter) in order to utilise the high precision.
