IKO ST122332B ST - Series

Rotary and linear motion Steel balls held in a retainer are assembled into an outer ring having a cylindrical raceway on the inside, so linear motion as well as rotary movement can be achieved. Extremely accurate The outer ring and shaft are precisely super-finished after heat treatment. The assembled set, which consists of an outer ring, shaft and very precise steel balls held in a retainer, is set to zero or minimal preload. So extremely accurate operation can be achieved both in rotary and linear motion. Extremely compact size Very small diameter steel balls are assembled in a very thin walled outer ring. So the assembled set is extremely compact in sectional height. Very smooth movement All parts are precisely finished and assembled to obtain an optimal preload. This series offers very smooth and stable movement as well as high accuracy with low frictional resistance.
