Deep Groove Ball Bearings SKF 6317

The SKF 6317 deep groove ball bearing, with a bore of 85 mm and an outside diameter of 180 mm, provides a robust bearing solution for high radial loads.

The 6317 deep groove ball bearing is a single-row radial ball bearing in an open design, conforming to standard tolerance class P0/PN (ABEC 1). Manufactured from 100Cr6 rolling-bearing steel in the SKF Explorer design, this construction primarily accommodates radial forces as well as moderate axial forces in both directions. As the bearing has neither cover plates nor sealing rings, lubricant reaches the rolling elements and raceways unimpeded. The integrated sheet steel cage guides the balls evenly at operating temperatures between –20 and +120 degrees.

In which applications is the 6317 deep groove ball bearing used?

This rolling bearing is primarily used in rotating shaft mountings, gearbox units and industrial powertrains. It is suitable for environments where an external housing seal is present and continuous oil lubrication or relubrication takes place. The open design, without abiding sealing elements, facilitates unimpeded lubricant flow and helps to maintain a stable operating temperature even under continuous load.

What are the characteristics of the open design with standard radial bearing clearance?

The open design without sealing discs allows for the free choice of lubricant and facilitates integration into existing lubrication circuits. As there are no sealing lips rubbing against the rotating inner ring, this rolling bearing operates with minimal frictional resistance. The version with standard radial bearing clearance is suitable for standard fits without excessive temperature differences between the shaft and housing. Before assembly, the dimensions of 85 mm inner diameter, 180 mm outer diameter and 41 mm width must be checked.
