Deep Groove Ball Bearings FAG 6317 -C3

The FAG 6317-C3 deep-groove ball bearing, with dimensions of 85 × 180 × 41 mm and increased bearing clearance, ensures reliable operation under thermal stress.

The 6317-C3 deep groove ball bearing is a single-row radial ball bearing in an open design. Manufactured from standard rolling bearing steel 100Cr6, this bearing primarily accommodates radial forces as well as axial forces in both directions. The design, which features no flange or groove on the outer ring, facilitates cylindrical mounting in the housing. Thanks to its manufacture to standard tolerance P0 or ABEC 1, the component fits precisely into standardised bearing seats in industrial drivetrains.

What is the 6317-C3 deep groove ball bearing suitable for?

Typical applications can be found in general mechanical engineering, as well as in gearboxes and industrial drive units. Thanks to its robust sheet-steel cage, the bearing guides the rolling elements with low vibration at medium to high speeds. As there are no integrated sealing washers to generate frictional heat, the rotational resistance remains low. Design engineers prefer to use this open variant in enclosed assemblies where an existing lubricant bath or a continuous oil circulation system supplies the rolling elements directly.

What advantages does the C3 clearance offer in this open rolling bearing?

The designation C3 indicates an increased radial clearance compared with the standard version. This increased clearance between the balls and raceways helps to prevent the bearing assembly from becoming stressed when operational heat causes the shaft to expand thermally. Similarly, the C3 bearing clearance compensates for tight fits on the inner or outer ring without the rolling elements becoming jammed. With a permissible operating temperature range of -20 to +150 degrees, this component is therefore suitable for applications involving significant heat generation.
