Gibraltar BHG3741-G Steel Shoulder Bushing 1-1/2 in Id

Product Description

The GIBRALTAR BHG3741-G is a steel die mold shoulder bushing designed to guide, align, and support mold components in die and mold tooling applications. Built as a friction-type, non-self-lubricating bushing, it relies on proper lubrication during installation and service. The part features a 1-1/2 inch inside diameter, a head diameter of 2-3/16 inches, a head height of 3/16 inch, and an overall length of 1-7/8 inches. It is constructed from steel for durability under load and repeated cycling. Toolmakers, mold technicians, and machine shop professionals are the primary installers of this component.

This shoulder bushing is suited for use in die sets, injection molds, stamping dies, and similar precision tooling assemblies. The shoulder head seats against the mold plate to provide positive axial location, while the body provides a precision bore for guide pin or leader pin engagement. It is used in both production tooling and toolroom maintenance and repair scenarios where accurate component alignment is critical to part quality and die life.

Key Features

• Steel construction for strength and wear resistance under repeated cycling
• Friction bushing type — requires external lubrication for proper operation
• 1-1/2 inch inside diameter for guide pin fitment
• Shoulder head diameter of 2-3/16 inches provides positive axial seating in mold plate
• Compact 1-7/8 inch overall length suits standard mold plate thicknesses
• 3/16 inch head height for low-profile shoulder seating

Compatibility

Designed as an OEM-style replacement or direct fitment component for die sets and mold bases requiring a friction-type shoulder bushing with a 1-1/2 inch inside diameter and 1-7/8 inch overall length.

Installation Notes

Installation is typically performed by toolmakers or mold technicians using a press fit into the mold plate bore. The mold or die set should be fully de-energized and secured before any bushing removal or installation. Because this is a non-self-lubricating friction bushing, apply the appropriate lubricant to the bore and mating guide pin before assembly and at regular service intervals. Verify bore tolerances in the mold plate match the bushing outer diameter before pressing to avoid galling or damage to the tooling.
