RS PRO Bronze Plain Bushes
RS PROs plain bushes are cylindrical components made from bronze used to support and guide spur gears. Spur gears are a type of cylindrical gear that have straight teeth that run parallel to the axis of rotation and are used to transmit power between two parallel shafts. The primary purpose of a bush is to help the gears rotate smoothly and without excessive friction, while also reducing wear and tear on the gears themselves.

- Sintered bronze bush
- Oil-less
- Suitable for use with Delrin gears
