Gibraltar BHG3693-G Steel Shoulder Bushing 0.5in Id

Product Description

The GIBRALTAR BHG3693-G is a steel die mold shoulder bushing designed for precision tooling and mold applications. This friction-type bushing features a 0.5-inch inside diameter and an overall length of 2.875 inches, making it suited for guided components in die sets and mold bases. The stepped shoulder design provides a 0.875-inch top outside diameter that seats against a mating surface, while the 0.7505-inch bottom outside diameter fits into the bore. It is non-self-lubricating, requiring periodic lubrication during service. Toolmakers, machinists, and die maintenance technicians typically install and maintain this style of bushing in production tooling environments.

This bushing is used in die mold assemblies where controlled guidance and precise bore alignment are required. Typical applications include injection molds, die casting tooling, stamping dies, and other precision fixture work where a shouldered bushing must locate and retain a moving component. The part is sold individually and is appropriate for both original tooling builds and maintenance replacement in existing die sets.

Key Features

• Stepped shoulder design with 0.875-inch head diameter and 3/16-inch head height for positive seating
• 0.7505-inch bottom outside diameter for controlled press or slip fit into tooling bores
• 0.5-inch inside diameter provides a consistent guided bore for punch pins or leader pins
• Non-self-lubricating friction bushing — compatible with applied lubricants used in die maintenance
• Steel construction for durability under repetitive load cycles in production tooling
• Sold as individual piece for single-unit replacement or new tooling builds

Compatibility

Designed as an OEM-style replacement or new-build component for standard die mold assemblies requiring a shoulder bushing with 0.5-inch inside diameter and 2.875-inch overall length.

Installation Notes

Installation is typically performed by a toolmaker or machinist during die build or maintenance. The die set or mold should be fully de-energized, depressurized, and secured before bushing removal or installation. A press fit may require an arbor press and properly sized driver to seat the bushing without distorting the bore. Inspect the mating bore for wear or damage before installing a replacement bushing, and apply appropriate lubrication per the tool design requirements before returning the assembly to service.
