Quick-Ship Slip/Fixed Renewable Bushings (SF)

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.

Quick-Ship Drill Bushings are popular bushing sizes that we do our best to keep in stock and ready for same-day shipment 100% of the time. These bushings include most common ID drill sizes. Complete part numbers for all quick-ship P bushings are listed in the tables below.

No-Counterbore Option on Long Bushings*

Extremely long bushings with a small ID size (marked with an asterisk * in the tables below) 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:

SF-20-16-.1250-NCB (Special)
