Headed Press Fit Bushing Dimensions Table

Headed Press Fit Bushing (Type H) Dimensions according to ASME B94.33. All dimensions are given in inches. Press fit bushings to guide the tool are installed directly in the jig without the use of a liner, and are employed principally where the bushings are used for short production runs and will not require replacement. They also are intended for use where the closeness of the center distance of holes will not permit the installation of liners and renewable bushings. Press fit bushings are made in two types: with heads and without
