Carr Lane SFM-10-25-4.50 | Slip/Fixed Renewable Bushing

Slip/Fixed Renewable Bushings-Metric

Metric version of the popular SF bushing. These replaceable SFM 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. SFM bushings combine the benefits of older S-type slip-renewable and F-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.

Application Information

These replaceable bushings are generally used with a liner bushing and lockscrew.

Counterbore on Small Drill Sizes

Metric bushings with small drill sizes through .80mm are counterbored 1.00mm diameter with 3mm drill-bearing length, according to ANSI standards, to eliminate binding and heat buildup.

Material

1144 Stressproof steel, heat treated to achieve Rc 62-64 ID hardness. DFARS and RoHS compliant.
