Deep Groove Ball Bearings SKF 6317 -2RS1

The SKF 6317-2RS1 deep groove ball bearing, measuring 85 x 180 x 41 mm, offers protection against dirt under predominantly radial loads.

The single-row deep groove ball bearing 6317 -2RS1 is a versatile rolling bearing for industrial applications. With an inner diameter of 85 mm, an outer diameter of 180 mm and a width of 41 mm, the component primarily absorbs radial forces, but also supports shafts axially in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel, it ensures high dimensional stability. As it is designed to the SKF Explorer performance class, the bearing is suitable for demanding continuous-duty applications in mechanical engineering.

For which operating conditions is the 6317-2RS1 deep groove ball bearing designed?

This radial ball bearing is used where rotating shafts are supported and where ambient dust and splash water are present. The sheet steel cage guides the rolling elements with low vibration under predominantly radial loads. The design, which is sealed on both sides, retains the lubricant inside the bearing, thereby eliminating the need for external lubrication in enclosed assemblies or hard-to-reach areas of machinery.

What is the function of the seal and bearing clearance in this design?

The designation 2RS1 stands for abiding sealing discs fitted on both sides. These sealing lips rest against the inner ring and effectively keep out dirt particles and moisture. In combination with the standard radial bearing clearance, the roller bearing is designed for normal operating temperatures between –20 and +120 degrees. Where the shaft is subject to significant thermal expansion, versions with increased bearing clearance may be required.
