Deep Groove Ball Bearings FAG 6212 -Z

The FAG 6212-Z deep-groove ball bearing, with dimensions of 60 × 110 × 22 mm and a single-sided sheet metal cover, offers a robust solution for rotating shafts.

The 6212-Z deep groove ball bearing is a single-row radial ball bearing with a bore of 60 mm, an outside diameter of 110 mm and a width of 22 mm. Manufactured from standard roller bearing steel 100Cr6, the design accommodates radial forces as well as axial loads in both directions. This version has standard radial clearance and is designed for a temperature range of -30 to +150 degrees Celsius.

In which bearing arrangements is the 6212-Z deep groove ball bearing used?

This design is suitable for bearing arrangements subject to combined loads and rotating shafts in general mechanical engineering. The integrated sheet steel cage ensures uniform guidance of the rolling elements at both normal and elevated speeds. A typical application is where the open bearing side allows lubricant to be supplied via the housing cavity, whilst the cover shield protects the raceway from the ingress of particles.

What is the function of the single-sided Z cover plate?

The suffix ‘Z’ denotes a non-contacting cover ring made of profiled sheet steel on one side of the bearing. Designed as a gap seal, the ring does not generate any additional frictional torque on the rotating components. The opposite side remains open to allow for lubricant exchange within the housing. In accordance with tolerance class P0 (ABEC 1), the rolling bearing is suitable for standard fits on cylindrical shaft seats.
