Description

Self-aligning ball bearings 11212 TN9

60*110*62mm bearings

11212 TN9 bearings
Self-aligning ball bearings 11212 TN9 have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. The bearings 11212 TN9 are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
11212 TN9 bearings is well suited to applications where considerable shaft deflections or misalignment are anticipated. In addition, the self-aligning ball bearing has the lowest friction of all rolling bearings which enables it to run cooler even at high speeds.
