Cyber Week Deal Carr Lane Sf-144-16-1.7344 | 2-1/4" Od X 1" Length Slip/fixed Renewable Bushing Quality Assured [UNHYgzXc]

Slip/Fixed Renewable Bushings (SF)

drill bushings are replaceable bushings generally used with a liner bushing and lockscrew. Use SF bushings when you expect to replace bushings during the tooling's lifetime, or to switch bushings to perform multi-step operations with the same tooling. SF bushings combine the benefits of older S-type slip-renewable and F-type fixed renewable bushings: one side of SF drill bushings feature a lockscrew recess for fixed mounting; the other has a locking recess that allows the bushing to slip down, then rotate to lock in place. S and F types are now obsolete, and combination SF drill bushings will be supplied at no extra charge.

Application Information

No-Counterbore Option on Long Bushings

Extremely long bushings with a small ID size are counterbored according to ANSI standards for proper drill-bearing length to eliminate binding and heat buildup. Add "-NCB" for applications that require these bushings without a counterbore.
