Deep Groove Ball Bearings FAG 6316 -C3

The FAG 6316-C3 single-row deep-groove ball bearing, with dimensions of 80 × 170 × 39 mm and increased C3 clearance, ensures reliable operation under thermal stress.

This open deep-groove ball bearing 6316-C3 from FAG accommodates radial loads as well as axial loads in both directions. Manufactured from standard rolling-bearing steel 100Cr6, a sturdy sheet-steel cage guides the rolling elements evenly along the deep raceways. As it has no integrated seals, the bearing is suitable for designs with external housing seals and a targeted supply of lubricating oil or grease. The permissible temperature range is from –20 to +150 degrees Celsius.

In which applications is the open deep-groove ball bearing 6316-C3 required?

This design is suitable for bearing arrangements subject to combined radial and axial loads on an 80 mm shaft in clean, externally protected housing spaces. Thanks to its open design, the lubricant can be replaced or circulated directly via the housing. The bearing complies with tolerance class P0/PN (ABEC 1) and has a smooth outer ring without a flange or circumferential groove. It is designed for applications where a lubrication circuit is present.

What effect does the increased bearing clearance (C3) have on this FAG bearing?

The designation C3 indicates a slightly increased radial bearing clearance in the as-supplied condition compared with the standard version. If interference fits are selected for the shaft and housing, the inner ring expands or the outer ring is compressed, thereby reducing the operating clearance. The C3 bearing clearance helps to prevent the rolling elements from becoming stressed should additional temperature differences arise between the shaft and housing during operation. This ensures that the bearing continues to function correctly even in the event of thermal expansion.
