Series SR

The SR Series gearboxes are supplied pre-lubricated with synthetic oil in view of a maintenance-free lifetime without any need of oil replacement. The pre-reduction stage can also be used as a single-stage helical gearbox. To ensure a high standard of noise-free performance, efficiency and a long lifetime, gears are case-hardened, quenched and stress-relieved, and are ground on the profile of the involute.
