Deep Groove Ball Bearings FAG 6012 -2RSR-C3

The FAG 6012 -2RSR-C3 single-row deep-groove ball bearing combines a 60 mm bore with a ground seal on both sides and increased C3 bearing clearance for demanding radial loads.

The FAG 6012 -2RSR-C3 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 rolling bearing steel, with dimensions of 60 × 95 × 18 mm. Designed to accommodate high radial forces and moderate axial forces, the bearing features a robust sheet steel cage. The factory-fitted sliding seals on both sides protect the bearing interior from contamination. The P0 tolerance class (ABEC 1) ensures standardised fitting accuracy for a wide range of industrial repair and original equipment applications.

In which applications is the 6012-2RSR-C3 deep-groove ball bearing used?

Designs in drive systems, shaft mountings and gearboxes utilise this size where ambient dust or splashing water may be present. With an internal diameter of 60 mm and an external diameter of 95 mm, the unit fits into machine housings with the appropriate installation space. The permissible temperature range is from –20 to +100 degrees Celsius. Typical applications in general mechanical engineering include rotating shafts that require a contact seal and stable guidance accuracy during continuous operation.

What advantages do the seal and C3 bearing clearance offer in the 6012-2RSR-C3?

The designation 2RSR stands for abiding sealing lips fitted on both sides, which retain the lubricant inside the bearing and make it difficult for foreign particles to penetrate. In addition, the slightly increased C3 radial bearing clearance compensates for thermal expansion when the shaft and inner ring heat up during operation. Even with tight fits, the increased bearing clearance prevents internal stresses. The housing dimensions must be checked before installation; furthermore, the bearing does not have an electrically insulating protective coating.
