Char-Lynn S-Series Hydraulic Motors

The new improved Char-Lynn S Series Motors with optimized Geroler geometry offers enhanced performance with reduced drive-running angle, while retaining the overall package size of the original S series. Design improvements include upgraded steel end cap, O-Ring section seals and optimized Geroler set.

The Geroler set has precision-machined rollers in the outer ring which provide support with rolling contact between the star and ring. This improves mechanical efficiency, especially at start-up and at low speed conditions. Improvements incorporated into the latest S Series motor provide reliable leak-free performance and smooth operation at start-up conditions.
