MR772 is a two-stage foot-mounted helical gearbox in the M77 group. A 90 mm diameter and 170 mm length define its output-shaft reference. With large transmission components, the location of applied force matters, so include it in the enquiry for shaft and bearing-load assessment.

This is a base model record. Select ratio, motor or input interface and mounting position when ordering. Housing torque is a reference, not a guaranteed configured output. Price, stock and lead time require confirmation.
Is a heavy coupling described by torque alone?
No. Weight and position introduce additional loads that must be assessed separately.
