Deep Groove Ball Bearings FAG 6412 -C3

The 6412-C3 deep groove ball bearing from FAG Rolling Bearings features a 60 mm bore, a 150 mm outer diameter and increased radial clearance for industrial applications subject to thermal stress.

The 6412-C3 deep-groove ball bearing is a single-row radial ball bearing conforming to standard tolerance class P0/PN or ABEC 1. It features a sheet steel cage and is made from standard 100Cr6 rolling-element bearing steel. As this is an open design without seals, the bearing is particularly suitable for designs with external housing seals and a targeted lubricant supply. With dimensions of 60 × 150 × 35 mm, this design can accommodate both radial and moderate axial forces.

What is the 6412-C3 deep groove ball bearing suitable for in industrial applications?

Design engineers and maintenance technicians primarily use this rolling bearing in gearboxes, industrial drives or general mechanical assemblies with cylindrical shaft seats. The open design allows for free circulation of lubricant – oil or grease – within the housing. Thanks to its wide operating temperature range of –20 to +150 degrees, the component is also suitable for thermally demanding conditions. The standardised main dimensions also facilitate replacement during repairs and integration into existing designs.

What are the advantages of the C3 bearing clearance in the 6412-C3 deep groove ball bearing?

The C3 designation indicates increased radial bearing clearance. This internal clearance between the raceway and the balls compensates for thermal expansion during operation when the inner and outer rings reach different temperatures. Furthermore, the C3 bearing clearance prevents seizing in the case of tight fits on the shaft or housing. The open bearing requires a clean installation environment. Additional protection against dirt and moisture is provided by the surrounding housing.
