Lamina Guided Retainers are precision guide pin & bushing/retainer assemblies that occupy much less space in the die than traditional pin and retainer combinations.
Guide and retain the pad or stripper plate in progressive stamping dies, or use on stock rails and stock dies with a lifter plate. Lamina Guided Retainers reduce machining cost and save space within your die.

Lamina's advanced design offers the following features:
Tight Assembly Tolerances
- Superior guiding, with the same assembly clearance as traditional pins and bushings
- Greater positional accuracy
Strength at the Pad
- Accomplished with steel retaining clips
- No SHCS threaded into the pin
Strength at the Pin Head
- Unique one piece construction
Bronze Graphite-Plugged Bushing
- Longer life
- Self lubricating
- No galling
Greater Static Shear Load
- Pin Head
- Pin Pad Fastening End
Optional Mounting of Bushing
- Can be mounted on either side of the plate for additional clearance, solving design issues
- Greater strength
Lamina Guided Retainers are available in 5 pin diameters, ranging in 1/8 inch increment lengths from 3.50 to 16.00 inches. Two bushing lengths are offered for each pin diameter.

This table is for reference only. Design considerations should be based on your own calculations.
Table is based on average speed of around 25-35 SPM.
At least three units should be used, and they should be equally spaced and not in line.
If there is excessive side load on the pad, heel blocks should be added.
