Linear guides

In DIN ISO 10285, the dimensions, tolerances and terms of sleeve type linear ball bearings are described in the series 1, 3 and 5.

ISO Series 1: Compact range. In relation to the shaft diameter, the outer diameter and length are smaller than ISO series 3. The load rating is also lower. This range is normally used only in closed design.

ISO Series 3: Medium Range. In relation to the shaft diameter, the outer diameter and length are larger than ISO series 1. The load rating is also higher. This range is the most commonly used, in closed design and also in open design.

ISO Series 5: Rarely used range. Depending on the shaft diameter, the outer diameter and/or length are larger, same or smaller than ISO series 1 or 3. And at some sizes, the grooves for retaining rings and their distances to each other are differents.
