Gibraltar BHG3740-G Steel Shoulder Bushing 1-1/2 in Id

Product Description

The GIBRALTAR BHG3740-G is a steel die mold shoulder bushing designed to guide and locate components in die, mold, and fixture applications. It features a 1-1/2 inch inside diameter and a 1-3/8 inch overall length, with a 2-3/16 inch head diameter and a 3/16 inch head height. The shouldered head seats flush against a mating plate, providing positive axial positioning. Constructed from steel with a non-self-lubricating, friction-type design, this bushing requires periodic external lubrication in service. It is installed by machinists, tool and die makers, and maintenance technicians working with press tooling, injection molds, and precision fixtures.

This shoulder bushing is suited for use in die sets, mold bases, jigs, and fixture plates where accurate bore alignment and repeatable part location are required. The friction bushing design is appropriate for applications where the bushing is pressed or slip-fitted into a housing bore. It is commonly used in metal stamping, plastic injection molding, and general tooling environments across both job shop and production settings. A single unit is packaged per order.

Key Features

• Steel construction provides durability in high-load die and mold environments
• Shouldered head design ensures positive axial positioning in mating plates
• 1-1/2 inch inside diameter suits standard die set and mold base bore sizing
• Non-self-lubricating friction type requires external lubrication for optimal service life
• Compact 1-3/8 inch overall length fits space-constrained tooling assemblies
• 2-3/16 inch head diameter provides a stable seating surface against the plate face

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard die sets, mold bases, and precision fixture plates requiring a friction-type shoulder bushing with a 1-1/2 inch inside diameter.

Installation Notes

Installation is typically performed by a tool and die maker or machinist. The bushing should be pressed or slip-fitted into a properly sized and finished housing bore; ensure the bore diameter and surface finish meet the bushing fit class before installation. Deburr the bore and apply appropriate lubricant to the bushing bore surface before placing the assembly into service. Never drive the bushing in with impact tools that could distort the head or bore geometry.
