Reduce the inside diameter of a bearing to fit a particular axle size. Also known as spanner bushings, they also reduce wear on the axle when used in plain bores and with straight roller bearings. All have a hole for lubrication.

Washers slide over the bushing and add 3/32" to the hub length of your wheel. Multiple washers can be used to match the length of the bushing.
