Description
Competition eligibility
Legal for FIRST Tech Challenge (FTC) and FIRST Robotics Competition (FRC). Eligibility is set by each season's game manual — check the current rules before you compete.
The REX profile is a fusion of Round and HEX profiles which combines the best of both worlds. The six outer points of the hex are clipped to a common diameter so you can run the shafting in a round bore bearing. The flat-to-flat shape provides a positive drive when paired with REX profile components.12mm REX shafting is for those who want to over-build and sleep well at night. The 12mm diameter is still able to pass through the 14mm holes found throughout Sheen Robotics. Such a large diameter calls for a pillow block to support it in a rotating assembly.
