Deep Groove Ball Bearings SKF 6313 -2RS1/C3

The SKF 6313 -2RS1/C3 deep groove ball bearing combines a 65 mm bore with ground seals on both sides and a slightly increased C3 radial clearance.

The 6313 -2RS1/C3 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6), which primarily accommodates radial loads as well as axial loads in both directions. SKF manufactures this model with a sheet steel cage and a cylindrical outer ring without a groove or flange. With dimensions of 65 mm inside diameter, 140 mm outside diameter and 33 mm width, this design is suitable for medium to heavy-duty shaft support applications in general mechanical engineering.

Under what operating conditions is the deep groove ball bearing 6313-2RS1/C3 required?

This design is primarily used where dirt particles or moisture may affect the bearing location. The seals, which seal on both sides, shield the interior from contaminants and help to minimise lubricant loss. The permissible temperature range extends from –20 to +120 degrees Celsius, enabling the design to withstand a variety of thermal operating conditions.

What are the characteristics of the combination of C3 and 2RS1?

The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional radial clearance compensates for operational heating of the shaft or housing and prevents internal stresses. The designation 2RS1 refers to seals that seal on both sides. With the ‘Normal’ tolerance class (P0 or PN and ABEC 1) and rolling elements made of bearing steel, this bearing constitutes a functional unit for shaft mountings subject to thermal and mechanical stress.
