FEATURES: Knurled liner for cast-in-place or potted installation, incorporating a special locking tab that eliminates the need for a Lockscrew. ULD Un-A-Lok® Liners are permanent bushings used to hold SF renewable drill bushings (on the "slip" side only, not the "fixed" side). 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.
