Gibraltar BHG3745-G Steel Shoulder Bushing 1.5in Id

Product Description

The GIBRALTAR BHG3745-G is a steel die mold shoulder bushing designed for precision alignment and guidance applications in mold and die assemblies. This friction-type, non-self-lubricating bushing features a 1.5-inch inside diameter and an overall length of 3.875 inches, making it suited for applications requiring accurate bore-to-bore alignment under moderate load cycles. The head diameter measures 2.1875 inches with a head height of 0.1875 inches. Fabricated from steel, this bushing provides the structural integrity needed in demanding tooling environments. Licensed machinists, toolmakers, and die maintenance technicians are the typical installers for this component.

This shoulder bushing is intended for use in die sets, mold bases, and precision tooling fixtures found in metalworking and plastics manufacturing environments. It seats into a bored receiver hole and provides a replaceable wear surface for guided punch or leader pin assemblies. The non-self-lubricating design requires periodic external lubrication during service intervals. Typical applications include progressive die tooling, injection mold bases, and stamping die assemblies where controlled clearance fits are maintained between mating components.

Key Features

• 1.5-inch inside diameter for precise bore alignment in die and mold assemblies
• 3.875-inch overall length accommodates deep-set tooling configurations
• 2.1875-inch head diameter with 0.1875-inch head height for positive shoulder seating
• Steel construction provides durability under repetitive load and press cycling
• Friction bushing type with non-self-lubricating design requires scheduled lubrication
• Sold individually as a single-unit package

Compatibility

Designed as an OEM-style replacement or direct-fit component for die sets and mold bases requiring a shoulder bushing with a 1.5-inch inside diameter and 3.875-inch overall length in friction-type bushing configurations.

Installation Notes

Installation is performed by toolmakers or die maintenance technicians during die set assembly or component replacement. The die set or mold base should be fully de-energized and press equipment locked out before servicing any bushing. Bushing bores should be cleaned and inspected for wear or damage before pressing in the replacement component. Because this is a non-self-lubricating friction bushing, apply appropriate tooling lubricant to the bore and mating pin surface prior to assembly and at regular maintenance intervals.
