Carr Lane H-10-5-.0310 | 5/32″ OD x 5/16″ Length Head Press-Fit Bushing

Description

Head Press-Fit Bushings (H)

H Bushings are similar to P bushings, but with a head to resist heavy axial loads. Type H bushings are permanently pressed into the jig plate. H bushings are generally used for single-operation drilling or reaming, when you do not expect to replace bushings during the tooling’s lifetime. The head of type H bushings can be left exposed, or recessed by counterboring the installation hole.

Application Information

H bushings are permanently pressed into the jig plate. The head can be left exposed, or recessed by counterboring the installation hole.

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.
