Introduction
The self-aligning ball bearing was invented by SK. This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. It has two rows of balls and a common sphered raceway in the outer ring.Self-aligning ball bearings are available with either a cylindrical or tapered bore. And it has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
Application
Self-aligning ball bearings are used for commercial ground shafting applications:
Mining machinery,
power machinery,
heavy machinery
textile machinery
