Spacer

Product

A spacer is a rigid cylindrical part that can have 3 functions. The first is to join two others and keep them at a fixed distance apart. The second is to center or align 2 components, in which case the spacer's outside diameter must be very precise, to the order of ten microns. Finally, the third function, known as compression spacer, is designed to reinforce a component, usually of lesser strength than the spacer, i.e. plastic. In the second and third functions, the spacer is hollow, i.e. a screw passes through its inside diameter, which can also be the case for the first function.
