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

The Single Reduction Clamping Gearbox naturally pairs with a Plastic Clamping Bearing Block or VersaBlock to establish a standard drivetrain gear reduction (see the Bearing Block Spacing drawing for details). For those who wish to use a 6" wheel, VEXpro HTD belts & pulleys can be used to achieve the same result. Download the STEP file for this Application Example here.
