RS PRO Plain Bush, 3mm Shaft Diameter, 5mm Outside Diameter

RS PRO Bronze Plain Bushes

RS PRO’s 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.
