Vortex Shaft - 20DP Gear - 7T

Maximum Purchase:
50 units

The Vortex Shaft - 20DP Gear - 7T is compatible with the REV ION System and offers users the unique ability to achieve substantial gear reductions directly from the motor. This gear features a 7T 20DP design that is typically too small for an 8mm keyed input. However, it becomes possible when integrated into the motor shaft.

The Vortex Shaft - 20DP Gear - 7T is addendum shifted to an 8T pitch diameter. This allows you to calculate center-to-center distances as if it were an 8T gear rather than a 7T. This feature streamlines your gear reduction calculations and ensures precision in your designs.

Featuring a 1/2in hex section that drives the shaft and a built-in taper for effortless self-centering, much like a milling machine. When you secure the shaft using a #10-32 Shaft End Screw, the taper keeps your shaft perfectly centered as it's drawn in and locked into place within the NEO Vortex.
