LM Stroke Die-setting Ball Cage Models KS and BS Models KS/BS
With models KS and BS, a large number of precision steel balls (sphericity in mutual difference: 0.0005 mm) compliant with JIS B 1501 are incorporated in a lightweight, highly rigid ball cage. The balls are arranged along the circumference of the ball cage in spirals so that the ball raceways do not overlap with each other. It enables these models to be used over a long period without wear and to demonstrate high durability.
Basic load rating kN : Basic dynamic load rating 10.3 to 22.5 / Basic static load rating 3.82 to 10.9
