CAMCO RD Series of Roller Dial Index Drives have a robust, flexible design with superior load capabilities. These models feature short camshaft motion periods, due to oversized roller gear cam design, and are well suited for continuous running applications or for special motion requirements such as oscillating motions. This series of index drives also offer universal mounting – including a horizontal mounting option that’s ideal for trunion applications. The optional center thru-hole facilitates passage of electrical wiring, pneumatic lines, or mechanical linkages. These models are also designed with optional stationary center post with thru-hole to provide mounting for upper tool plates
