RA Series Worm Speed reducers are enclosed in an aluminum die-cast housing and cover, and are available in about seven different size options. ISM forms the input module that has a solid shaft and BSM module with a back-stop feature that can be flexibly mounted on most of the Varvel gearboxes.

The input shaft of ISM is supported by two 2RS bearings that are sealed and grease-packed, thereby eliminating the requirement for any further lubrication during its lifetime. ISM has half-coupling to facilitate direct coupling to gearboxes. BSM can be mounted to the Varvel gearboxes with flexible coupling via IEC or NEMA flanges.
