Deep Groove Ball Bearings SKF 6309 -2RS1

The SKF 6309-2RS1 deep groove ball bearing, measuring 45x100x25 mm, offers reliable protection against dirt thanks to abiding seals on both sides.

The 6309 -2RS1 deep groove ball bearing is a single-row rolling bearing designed primarily for radial loads, whilst also accommodating axial forces in both directions. SKF manufactures this bearing from standard 100Cr6 rolling-element bearing steel with a cylindrical bore. Thanks to factory greasing and double-sided sealing, the unit is protected from external influences during operation. Designers use this version primarily where solid particles or moisture need to be kept out of the bearing interior.

What is the 6309-2RS1 deep groove ball bearing suitable for?

This radial ball bearing is used for medium to heavy radial loads in combination with axial load components. The outer ring, which has no groove or flange, fits flush into cylindrical housing bores, whilst the sheet steel cage guides the balls precisely. The component is designed for a temperature range of -20 to +120 degrees. The design covers a wide range of industrial bearing applications where a sealed design is required.

What are the advantages of the 2RS1 double-sided seal?

The designation 2RS1 indicates abiding seals arranged on both sides. These sealing discs contact the inner ring and help to keep out dust and moisture, whilst ensuring that the lubricant remains within the bearing chamber. Compared with non-contact cover plates, sliding seals provide an effective barrier in dusty environments. Under normal installation conditions, the standard radial bearing clearance ensures smooth running within tolerance class P0.
