Dayton Lamina S1000-27G Shoulder Bushing 1 in Id

Product Description

The DAYTON LAMINA S1000-27G is a die mold shoulder bushing machined from aluminum bronze, a material valued in tooling applications for its strength, corrosion resistance, and natural lubricity. This bushing features a 1 inch inside diameter, a uniform 1.3755 inch outside diameter along both the bottom and top body sections, and a 1.55 inch collar outside diameter. The shoulder design provides a positive axial stop during press-fit installation, ensuring consistent seating depth in die sets, mold bases, and precision tooling assemblies. It is installed by toolmakers, die setters, and maintenance machinists working with injection molds, stamping dies, and similar tooling components.

This bushing is suited for use in die mold bases and precision tooling where controlled alignment and smooth guiding action are required. The self-lubricating aluminum bronze construction reduces the need for external lubrication in continuous or repetitive cycling applications. With a body length above the collar of 3-3/16 inches and a collar height of 3/16 inch, it fits standard die set configurations requiring a 1 inch nominal bore with a press-fit retention method.

Key Features

• Aluminum bronze construction provides self-lubricating, low-friction guiding performance
• Press-fit attachment method for secure, permanent installation in die and mold bases
• Shoulder collar design delivers a positive axial stop at 1.55 inches collar outside diameter
• Uniform 1.3755 inch outside diameter on both top and bottom body sections for consistent bore fit
• 3-3/16 inch length above collar suits deep guide applications in standard tooling assemblies
• Friction bushing type rated for high-cycle sliding contact without additional lubrication

Compatibility

Designed as an OEM-style replacement or original-fit component for die sets and mold bases requiring a 1 inch ID press-fit shoulder bushing in aluminum bronze.

Installation Notes

Installation is typically performed by a toolmaker or die maintenance machinist using an arbor press or hydraulic press to achieve the interference press-fit. The mold or die set must be fully de-energized, depressurized, and cooled before bushing removal or installation. Avoid striking the bushing directly with a hammer; use a properly sized press driver to prevent damage to the collar or bore alignment. Verify bore diameter and surface finish in the receiving plate prior to installation to ensure proper fit.
