Carr Lane HL-64-8 | Head Liner Bushings

Head Liner Bushings

Head Liners  are similar to L bushings, but with a head to resist heavy axial loads. HL liners are permanent bushings used to hold renewable drill bushings. The liner's ID has a precise sliding fit with the renewable bushing's OD. The liner accurately locates the renewable bushing and protects the jig plate from wear and damage caused by frequent bushing replacement.

Application Information
