1/4" ID Stainless Steel Shim (0.01" Thickness) - 12 Pack

A shim goes on a shaft up against a bearing. It's outer diameter is small enough that it does not touch the outside race of the bearing. Its purpose is to prevent a hub, gear, collar, sprocket, or pulley from contacting both the inner and outer race of the bearing. This shim has a 1/4" ID to fit on a 1/4" shaft.
