RKO Series

RKO

RKO series is a drop fit model for the RKE series, but with an open housing. An oxi-nitrocaurbarized externally geared slew ring meshes with a straight worm shaft allowing a teeth contact ratio of 1.8. Meshing the slew ring’s internally curved helical teeth with a straight worm allows for high tolerances and better backlash control when compared with other slew drives of the same size. The open housing model carries less housing material thus resulting in a lighter version than the RKE 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.
