Gibraltar STB-4506 Die Mold Straight Bushing Steel

Product Description

The GIBRALTAR STB-4506 is a straight-style die mold bushing machined from steel and designed for precision press-fit installation in die and mold tooling applications. With an inside diameter of 1.2505 inches and a body diameter of 1.6255 inches, this bushing provides a consistent, tight-tolerance bore for guiding punches, leader pins, or related tooling components. At 0.5 pounds, the part is compact and suited for benchtop or press installation. The non-self-lubricating construction means external lubrication must be applied during operation, giving the installer direct control over lubrication intervals and lubricant selection.

This bushing is intended for use in die sets, injection molds, stamping dies, and similar precision tooling assemblies. The press-fit attachment method eliminates the need for fasteners, relying on controlled interference fit to hold the bushing securely in the housing bore. Typical installation is performed by toolmakers, die setters, and machining professionals working in manufacturing and fabrication environments where dimensional accuracy is critical.

Key Features

• Straight bushing style for straightforward press-fit installation in die and mold plates
• Inside diameter of 1.2505 inches provides a precision bore for guided tooling components
• Body diameter of 1.6255 inches for interference-fit seating in the housing
• Steel construction for durability under repeated cycling and load
• Non-self-lubricating design allows technician-controlled lubrication schedules
• Compact at 0.5 pounds, suitable for benchtop press installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for straight-style die mold bushing applications requiring a 1.2505-inch inside diameter and press-fit attachment.

Installation Notes

Installation is typically performed by a toolmaker or die setter using an arbor press or hydraulic press to achieve proper interference fit. The housing bore should be inspected and cleaned before pressing the bushing into position to ensure accurate seating. Do not hammer the bushing in directly without a press plate or driver, as this can damage the bore or distort the bushing. Because this bushing is non-self-lubricating, apply an appropriate lubricant to the bore surface before placing guided components into service.
