Dayton Lamina 5-1629-82 Ball Bearing Guide Post 2in Od

Product Description

The DAYTON LAMINA 5-1629-82 is a press-fit ball bearing guide post used in metal stamping dies and progressive tooling assemblies. It features a 2-inch body diameter and an overall length of 7.25 inches, making it suitable for medium-to-large die sets that require precise, repeatable alignment. Constructed from hardened steel, the post provides the rigidity and wear resistance required for high-cycle press operations. Installation is accomplished by pressing the post directly into the die shoe, eliminating the need for threaded fasteners in the primary attachment. Thread size is 3/8-10 for any auxiliary retention or accessory hardware.

This guide post is intended for use in industrial press tooling environments, including blanking, forming, and progressive die sets. It is typically installed by tool-and-die makers or press maintenance technicians in manufacturing and metal fabrication facilities. The ball bearing design provides smooth, low-friction guidance between the upper and lower die shoes throughout the press stroke, which helps maintain alignment tolerances during production runs.

Key Features

• Press-fit attachment method for secure, interference-fit installation in die shoe bores
• Ball bearing post design for low-friction, precision alignment during press strokes
• 2-inch body diameter suited for medium-to-large die set applications
• 7.25-inch overall length provides adequate post engagement and clearance
• Hardened steel construction for high wear resistance in high-cycle tooling environments
• 3/8-10 thread size for auxiliary retention hardware compatibility

Compatibility

Designed as an OEM-style replacement or new-build component for medium-to-large industrial die sets requiring press-fit ball bearing guide posts with a 2-inch body diameter.

Installation Notes

Installation should be performed by a qualified tool-and-die maker using a hydraulic or arbor press to achieve the required interference fit without damaging the post or die shoe bore. The die shoe bore must be machined to the correct tolerance to ensure proper press-fit engagement. Ensure the press is fully de-energized and locked out before any die installation or removal work is performed. Consult the die set manufacturer specifications and applicable workplace safety standards before pressing components.
