8mm Pitch Press-Fit Pinion Sprocket (8mm REX Bore, 8 Tooth) - 2 Pack

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.

This pinion sprocket lets you drive your 8mm pitch chain in an assembly. It press-fits onto an 8mm REX shaft. The snug fit means you do not need to axially constrain the sprocket in most cases. The built-in shims on either side of this sprocket allow it to be pressed right up against a bearing without binding the inner and outer races or needing a separate shim. The acetal makeup of this part means it will be low-friction with excellent wear characteristics.

Supplied as a pack of 2.
