## Description

This hole reducer fits over an 8mm OD (or 8mm REX™) shaft and indexes into a 14mm hole. In some assemblies, 14mm bore hub-mount components can get farther away from the hub than is ideal. This hole reducer offers a means to remove the cantilever from your assembly by transferring the force from the 14mm bore down to the shaft.

Another use-case for this hole reducer is to allow you to use M8 hardware in a 14mm hole.
