Self Aligning Ball Bearing (Extended Inner Ring) 11212 TN 60x110x22 mm
Item number:
11212-TN
Item features:
With the swiveling and extended inner ring, the self aligning ball bearing 11212-TN offers excellent alignment error compensation. With the two rings of barrel-shaped rollers, it can absorb high radial forces. The assembly on the shaft is done with a tenon screw. Main dimensions according to DIN 630.

Features
- self-aligning ball bearing with two rows of balls
- pivoting inner ring, misalignments and shaft deflections can be compensated
- extended inner ring for easy installation and axial fixation by means of a tenon screw
- suitable for high radial loads and light axial loads in both directions
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- good fixed bearing property, but can also be used as a floating bearing, each in both directions
- manufacturers of bearings, such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)
