Deep Groove Ball Bearings SKF 6209 -2RS1

The SKF 6209-2RS1 deep groove ball bearing, measuring 45 × 85 × 19 mm and featuring seals on both sides, offers protection against dirt and moisture.

The 6209 -2RS1 deep groove ball bearing is a single-row radial rolling bearing from SKF made from standard bearing steel (100Cr6). Designed for a shaft diameter of 45 mm, the component primarily accommodates radial forces as well as moderate axial loads in both directions. A sheet steel cage guides the rolling elements evenly into the deep raceways. Thanks to the sliding seal, the bearing can be integrated directly into assemblies that require protection from environmental influences.

For which loads and installation situations is the 6209-2RS1 deep groove ball bearing suitable?

This bearing design is the preferred choice where rotating shafts need to be supported and ambient dust or moisture must be kept away from the raceways. As the outer ring is cylindrical and manufactured without a groove or flange, the 6209-2RS1 deep-groove ball bearing fits into standardised housing bores with an outer diameter of 85 mm. The design is suitable for applications involving predominantly radial loads and guidance on both sides.

What are the key features of the double-sided 2RS1 seal?

The suffix 2RS1 denotes two abutting sliding seals. These sealing lips rest against the inner ring and effectively keep out dirt particles and moisture, whilst the lubricant remains inside the bearing. In combination with the standard radial bearing clearance, the component is suitable for a temperature range of -20 to +120 degrees and complies with tolerance class P0 and ABEC 1.
