Deep Groove Ball Bearings SKF 62308 -2RS1

The SKF 62308 -2RS1 deep groove ball bearing, measuring 40x90x33 mm and featuring a ground seal on both sides, offers reliable protection against dirt and moisture.

The 62308 -2RS1 deep groove ball bearing is a single-row radial ball bearing manufactured by SKF. With key dimensions comprising a bore of 40 mm, an outer diameter of 90 mm and a width of 33 mm, the rolling bearing accommodates both radial and axial forces on both sides. Manufactured from standard roller bearing steel 100Cr6, the inner ring, outer ring and rolling elements are characterised by uniform hardness and dimensional stability. An integrated sheet steel cage guides the rolling elements along the raceway. The dimensional accuracy complies with tolerance class P0/PN, comparable to ABEC 1.

In which applications does the 62308-2RS1 deep groove ball bearing prove its worth?

This bearing design is used in industrial assemblies where rotating shafts need to be guided and external particles must be kept out. The design is suitable for bearing arrangements subject to combined radial and axial loads. Thanks to the cylindrical outer ring without a flange or groove, the rolling bearing fits positively into the corresponding housing bores. The design is intended to combine mechanical stability with sealed protection against contamination.

What are the key features of the 2RS1 seal and the bearing clearance?

The 2RS1 seal, which abuts on both sides, protects the raceways from ingress of contaminants and moisture, whilst the factory-applied lubricant is retained inside the bearing. Together with the standard radial bearing clearance, the assembly maintains dimensional stability within an operating temperature range of –20 to +120 degrees Celsius. This design is tailored to standard mounting fits, thereby ensuring thermal compensation during standard operation. The sealed design reduces the need for additional external components at the bearing location.
