Deep Groove Ball Bearings SKF 6309 -2RS1/C3

The SKF 6309 -2RS1/C3 deep groove ball bearing combines contact seals with increased bearing clearance, with dimensions of 45x100x25 mm, for a wide range of industrial applications.

The 6309 -2RS1/C3 deep groove ball bearing primarily accommodates radial forces as well as axial loads in both directions. This single-row roller bearing, made from standard 100Cr6 bearing steel, features a robust sheet steel cage that guides the rolling elements with precision. Thanks to its sealed design with seals that rub against both sides, the component protects the raceways from the ingress of dust and moisture at operating temperatures ranging from -20 to +120 degrees.

What are the industrial applications for the 6309-2RS1/C3 deep groove ball bearing?

Industrial bearing arrangements subject to combined radial and axial loads constitute the main area of application for this deep groove ball bearing when protection against external environmental influences is required. This design is recommended for constructions in which heat is generated during operation or where fits are selected that reduce the operating clearance. The sealed design ensures smooth running during continuous operation and accommodates combined loads in general mechanical engineering.

What are the advantages of the C3 clearance and the 2RS1 seal?

The version with the suffix C3 has a slightly increased radial bearing clearance compared with the standard version. This additional operating clearance serves to compensate for temperature- or assembly-related expansion of the shaft and housing, so that the rolling elements can roll freely. At the same time, the two 2RS1 sealing lips shield the internal space from dirt particles, whilst the cylindrical outer ring without a groove facilitates installation in standard housings to tolerance class P0.
