Mechanical Rotary Indexers

Destaco’s RD Series of roller dial index drives are designed with a robust, flexible design with superior load capabilities.


Roller Dial Index Drives offer superior load capabilities making them ideal for medium to high torque applications. Other features include:
  • Universal mounting including horizontal mounting ideal for trunnion applications
  • Center thru hole facilitates passage of electrical wiring, pneumatic lines or mechanical linkages
  • Short camshaft motion periods are well-suited to continuous running applications or for special motion requirements
  • Available with custom motions such as oscillating motions
