Single Reduction Clamping Gearbox

The Single Reduction Clamping Gearbox achieves versatility through its simplicity. This gearbox uses four bolts to clamp onto a piece of 1" x 2" VersaFrame tube - no precision machining needed. Once mounted, it mounts a CIM-style motor offset from a bearing block on a perfect 84-tooth gear spacing. Use this efficient setup to drive an upper mechanism with ease, or combine multiple gearboxes to create a smooth-running, lightweight VersaChassis.

  • Simple design for quick assembly and maintenance

  • Variety of gearing options

  • Combines with the Plastic Bearing Block for a second stage reduction
