Product Description
Separable Self Aligning Ball Bearing 25mm Low Friction For Semiconductors
Description:
The self-aligning ball bearing was invented by SKF. It has two rows of balls and a common sphered raceway in the outer ring. The bearings are consequently self-aligning and insensitive to shaft deflections and angular misalignment of the shaft relative to the housing. Additionally, self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.Self-aligning ball bearings are available with either a cylindrical or tapered bore. Bearings with a tapered bore can be mounted directly on a shaft or on an adapter or withdrawal sleeve.
Feature:Open self aligning ball bearings of basic design. Sealed self aligning ball bearings
Open self aligning ball bearings with an extended inner ring.
