Metallic bore reducers for use with acetal fork type universal joints, adjustable friction clutches, nickel bellows couplers and Uni-lat zero backlash shaft couplers Designed to adapt the bore size, thereby increasing the offering of diameters available. When fitted into hubs with set screws, these reducers function as ring clamps leaving the shafts unmarked Shafts can be removed or re-positioned repeatedly without disturbing the reducers, which remain in the hubs Close tolerance shafts are recommended as grip relies on adequate contact area between shaft and reducer Operating temperature range: -40°C to +85°C
