Dayton Lamina ME875 Shoulder Ejector Bushing 0.875in Id

Product Description

The DAYTON LAMINA ME875 is a die mold shoulder ejector bushing designed for press-fit installation in injection mold and die casting tooling applications. This self-lubricating bushing features a 0.875 inch inner diameter and an overall length of 1.5 inches, with a body diameter of 1.2505 inches and a collar outer diameter of 1.427 inches. The shoulder design provides a positive stop during installation, with 1 inch of length above the collar and 0.5 inches under the collar. Licensed toolmakers, moldmakers, and die maintenance technicians specify this style of bushing when a guided, self-lubricating ejector interface is required for consistent pin or core alignment throughout the production cycle.

This ejector bushing is suited for use in injection mold bases, die cast tooling, and stamping die assemblies where shoulder-style press-fit bushings are required. The self-lubricating construction reduces the need for manual lubrication at the ejector interface, supporting higher-cycle tooling environments. It is installed directly into a machined pocket in the mold plate or die block.

Key Features

• Press-fit shoulder design provides positive seating and repeatable positioning in the mold plate
• Self-lubricating construction reduces maintenance intervals at the ejector pin interface
• 0.875 inch inner diameter accommodates standard ejector pin sizing
• 1.2505 inch body diameter ensures consistent press-fit engagement in the bored pocket
• 1.427 inch collar outer diameter acts as a positive stop against the mold plate surface
• 1.5 inch overall length with 1 inch above collar and 0.5 inches under collar

Compatibility

Designed as an OEM-style replacement or direct-fit component for die mold and injection mold assemblies requiring a shoulder ejector bushing with a 0.875 inch inner diameter and press-fit body diameter of 1.2505 inches.

Installation Notes

Installation is typically performed by a toolmaker or die maintenance technician. The mold or die assembly should be fully de-energized, de-pressurized, and cooled before bushing removal or installation. A properly sized arbor press is recommended for press-fit seating to avoid cocking or damage to the bore. Verify bore diameter tolerance in the mold plate against the bushing body diameter before pressing to ensure proper interference fit.
