1215EKTN Double Row Self-aligning Ball Bearing
Product Application
The 1215EKTN 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.
