Deep Groove Ball Bearings FAG 6015 -C3

The FAG 6015-C3 single-row deep-groove ball bearing, with its increased C3 clearance and dimensions of 75 × 115 × 20 mm, offers reliable running characteristics under thermal loads.

The FAG 6015-C3 deep groove ball bearing is an open, single-row radial ball bearing to standard tolerance class P0/PN (ABEC 1). The rings and rolling elements are made from standard roller bearing steel 100Cr6. A sturdy sheet steel cage guides the balls evenly along the raceways. As it does not feature integrated sealing washers, this model is suitable for designs with external housing seals and targeted lubricant circulation within a temperature range of –20 to +150 degrees Celsius.

What is the 6015-C3 deep groove ball bearing suitable for in industrial applications?

This rolling bearing primarily accommodates radial forces as well as moderate axial loads in both directions. Design engineers use the 6015 size primarily in rotating machine components and industrial shaft bearings with a shaft diameter of 75 mm. As there are no seals to create frictional resistance, the open design ensures smooth running. The bearing can be suitably incorporated into enclosed machine housings with continuous oil or grease lubrication.

What characterises the increased C3 bearing clearance in this bearing?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This additional clearance is required when temperature differences arise between the inner and outer rings during operation. If the shaft expands more than the housing, the increased radial clearance helps to prevent the rolling elements from becoming stressed. Tight fits on the shaft or housing also reduce the operating clearance after press-fitting, which effectively compensates for the C3 classification.
