Gibraltar BHG3733-G Steel Shoulder Bushing 1.2505in Id

Product Description

The GIBRALTAR BHG3733-G is a steel die mold shoulder bushing designed for precision alignment and guided motion in tooling and mold assemblies. It features a 1.2505-inch inside diameter, a 2.875-inch overall length, and a press-fit attachment method that locks the bushing securely into a bored hole without fasteners. The stepped shoulder design — with a 1.6255-inch bottom outside diameter and a 1.8020-inch top outside diameter — provides a positive seating surface that controls insertion depth and resists axial pullout. This part is non-self-lubricating, requiring periodic lubrication as part of routine maintenance. Toolmakers, die setters, and mold technicians are the primary installers.

This bushing is suited for use in stamping dies, injection mold bases, and precision jig and fixture assemblies where tight tolerances and repeatable alignment are required. It is commonly installed in die sets to guide punch and die components or to locate mold halves during cycling. The friction bushing design makes it appropriate for lower-speed, higher-load applications where sliding contact occurs under controlled lubrication.

Key Features

• 1.2505-inch inside diameter for precision bore fit
• Press-fit attachment method — no fasteners required
• Stepped shoulder with 1.6255-inch bottom OD and 1.8020-inch top OD controls insertion depth
• 1.8125-inch head diameter with a 0.1875-inch head height provides positive seating surface
• Steel construction for durability in die mold and tooling environments
• Non-self-lubricating friction bushing — compatible with periodic manual lubrication routines

Compatibility

Designed as an OEM-style replacement or direct-fit component for die sets, mold bases, and precision tooling assemblies requiring a shoulder bushing with a 1.2505-inch bore and press-fit installation.

Installation Notes

Installation is performed by qualified toolmakers or die setters using an arbor press to drive the bushing into a properly bored and toleranced hole. Ensure the bore diameter and finish meet the manufacturer press-fit specifications before installation. Power down and de-energize any associated press or machinery before servicing tooling components. Apply appropriate lubricant to the bore contact surface per shop maintenance standards before placing the assembly into service.
