Dayton Lamina 6-20-48 Bronze Shoulder Bushing 2.5 in Id

Product Description

The DAYTON LAMINA 6-20-48 is a bronze die mold shoulder bushing designed for use in die sets and mold bases where precise, repeatable alignment is required. This demountable, friction-type bushing features a 2.5 inch inside diameter, a bottom outside diameter of 3.659 inches, and a collar outside diameter of 3.814 inches. It is non-self-lubricating, meaning proper lubrication must be applied during assembly and service intervals. Licensed toolmakers, die setters, and mold technicians typically specify this bushing when building or maintaining stamping dies and injection mold tooling.

This bushing is suited for precision tooling applications in industrial and manufacturing environments. The shoulder design provides a positive stop against the die plate, ensuring consistent seating depth during installation. With a length under collar of 2.5 inches and a length above collar of 1.875 inches, it fits die sets requiring a standard shoulder-style guide bushing. The demountable attachment method allows for field replacement without scrapping the die plate or mold base.

Key Features

• Bronze construction provides good wear resistance and machinability in die and mold tooling environments
• 2.5 inch inside diameter for compatibility with matching guide pins or leader pins
• Demountable design allows in-field replacement without plate damage
• Shoulder body type provides a positive, repeatable seating stop against the die plate
• Non-self-lubricating friction type requires scheduled lubrication for optimal service life
• Compatible with clamp style 6-91-1 for secure retention in the die set

Compatibility

Compatible with clamp style 6-91-1. Designed as an OEM-style replacement or new-build component for die sets and mold bases requiring a demountable bronze shoulder bushing with a 2.5 inch inside diameter.

Installation Notes

Installation should be performed by a qualified toolmaker or die technician with the press or molding machine fully de-energized and locked out per OSHA lockout/tagout procedures. Ensure the bushing bore and mating guide pin are clean and properly lubricated before assembly. The demountable design typically requires the appropriate clamp hardware to secure the bushing in the plate. Inspect mating guide pins and the plate bore for wear or damage before installing a replacement bushing.
