FEATURES: Carbide version of our popular SF bushing, for high-production applications. Replaceable SFC bushings are generally used with a liner bushing and lockscrew. Use when you expect to replace bushings during the tooling's lifetime, or to switch bushings to perform multi-step operations with the same tooling. SFC bushings combine the benefits of older SC-type slip-renewable and FC-type fixed renewable bushings: one side has 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. Carbide bushings are available in all three types: SFC, SC, and FC.
