Deep Groove Ball Bearings FAG 6314 -C3

The FAG 6314-C3 deep-groove ball bearing, with dimensions of 70 x 150 x 35 mm and increased bearing clearance, offers defined running characteristics under temperature variations.

The single-row deep groove ball bearing 6314-C3 from FAG is a rolling bearing designed primarily for radial loads. With an inside diameter of 70 mm, an outside diameter of 150 mm and a width of 35 mm, this design can also accommodate moderate axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, this open rolling bearing is designed for a temperature range of –20 to +150 degrees.

In which operating conditions does the 6314-C3 deep groove ball bearing prove its worth?

The 6314-C3 deep groove ball bearing is suitable for mounting positions where, due to operational conditions, temperature differences arise between the shaft and the housing. Thanks to its open design, the bearing can be integrated directly into protected housings with oil or grease lubrication, which allows for the selection of an application-specific lubricant and regular relubrication.

The sheet steel cage guides the rolling elements along the raceway and maintains a uniform spacing between them. As the outer ring is manufactured without a flange or groove, it is fitted directly into through cylindrical housing bores.

What is the function of the increased bearing clearance C3 in the deep-groove ball bearing 6314?

The design with a slightly increased radial clearance (C3) serves to maintain the internal operating clearance when the shaft heats up or due to tight-fit seats. If, during operation, the inner ring expands more than the outer ring, the increased bearing clearance compensates for this difference and ensures smooth running of the rolling bearing.

In conjunction with tolerance class P0 or ABEC 1, a standardised component is available for standardised mounting conditions.
