Description
Diamond-Knurl Un-A-Lok Liner Bushings
Knurled liner for cast-in-place or potted installation, incorporating a sturdy locking tab that eliminates the need for a Lockscrew. ULD Un-A-Lok Liners are permanently installed bushings used to hold SF renewable drill bushings. Diamond-knurled OD provides excellent holding strength against both rotational and axial forces. Since the bushing’s OD is not ground, the ID must be accurately located during casting or potting to ensure accuracy in the finished tool.
