RSO Series

RSO

RSO series is a drop fit model for the RSE series, but with an open housing.

An externally geared slew ring with heated treated teeth meshes with a globoid worm shaft allowing 5 teeth to be contact at any point during rotation. Meshing the slew ring’s straight hardened helical teeth with globoid worm allows for better back holding torque. The open housing model carries less housing material thus resulting in a lighter version than the RSE series while yielding same performance. Recommended for applications where working environment is somewhat controlled to avoid debris from entering between the gear teeth.

Standard imperial drives are designed with a standard 1” 6B spline on the right- hand side of the worm shaft input and a 24mm hex head on the left-hand side for manual rotation. Standard metric drives are designed with a 25mm keyway on the right- hand side of the worm shaft input and a 24mm hex head on the left-hand side for manual rotation.

Worm shaft inputs can be altered during manufacturing to support customer requests for specific motor output shaft dimensions as well right- hand side and left-hand side orientation.
