Deep Groove Ball Bearings FAG 6012 -2Z-C3

The FAG 6012 -2Z-C3 single-row deep groove ball bearing combines main dimensions of 60 × 95 × 18 mm with cover plates on both sides and increased C3 bearing clearance for shaft mountings subject to thermal stress.

The 6012 -2Z-C3 deep groove ball bearing is a single-row radial ball bearing with a 60 mm bore, 95 mm outer diameter and 18 mm width. FAG manufactures this rolling bearing from standard 100Cr6 bearing steel for combined radial and axial loads in mechanical and plant engineering. Fitted with a robust sheet steel cage and metal lip seals on both sides, the design protects the interior against coarse dirt particles. This version is suitable for operating temperatures ranging from -30 to +120 degrees.

What is the 6012 -2Z-C3 deep groove ball bearing suitable for in industrial applications?

The 6012 -2Z-C3 deep groove ball bearing is primarily designed to accommodate combined radial loads and axial forces in both directions. Thanks to its low-friction operation, the bearing drives rotating shafts at higher speeds. Compared to sliding seals, the non-contacting cover plates do not generate any additional frictional heat. This design is suitable for applications where protection against solid particles and dirt is required without the sealing effect of the seal.

What is the function of the C3 bearing clearance in the 6012-2Z-C3 deep groove ball bearing?

The designation C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance between the balls and raceways compensates for thermal expansion when temperature differences occur between the inner and outer rings during operation. Furthermore, the radial clearance is reduced by tight press fits on the shaft or in the housing. With tolerance class P0 (ABEC 1) and the cylindrical outer ring without a flange, the bearing can be fitted into standardised housing bores.
