(24) These are very high precision quality bearings use in instruments requiring minimal runout, eccentricity, and wobble during rotation. They can replace back-to-back or face-to-face mounted angular contact bearing pairs allowing for a compact design where space is limited. You will find these in rotary stage applications where you wish to move an object in a very precise circular or oscillating motion.
Special features:
Integral tapped mounting holes for ease of mounting to flat surfaces.
Designed for low height using 4 point contact ball bearing to support load
The bearings are manufacturered in two quality classes Normal or Precision ...
