Self-aligning Ball Bearings 1210 ETN9
The 1210 ETN9 bearing is a Self-aligning ball bearings with an inner diameter of 50 mm , an outer diameter of 90 mm, a width of 20 mm. It typically uses p6 grade precision tolerances and open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
The self-aligning ball bearing has two rows of balls and a common concave sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
We produces self-aligning ball bearings to several designs.
These are open bearings of the basic design
sealed bearings
open bearings with an extended inner ring

This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.
