8mm REX Plastic Spacer (12mm REX™ OD, 8mm Length) - 12 Pack

This 8mm length, 8mm REX™ bore spacer is designed for sliding onto an 8mm REX™ shaft to create space between parts. Your choice of spacer length can ensure the correct alignment of drive components, such as gears and sprockets, as well as axially restrain components (such as bearings) to provide for a well-spaced and solid build!
