Dayton Lamina 5-0813-82 Ball Bearing Guide Post 1 in Od

Product Description

The DAYTON LAMINA 5-0813-82 is a press-fit ball bearing guide post designed for precision die and mold applications. It features a 1 inch outer diameter and a 3.25 inch overall length, constructed from hardened steel for extended wear resistance under high-cycle stamping and forming conditions. The press-fit attachment method allows secure installation into die sets and mold bases without additional fasteners. A 5/16-18 threaded section is included for retention or puller use during service. This component is typically installed by tool and die makers or mold technicians working on metal stamping dies, injection mold bases, or progressive die assemblies.

Ball bearing guide posts are used in metal stamping, blanking, and progressive die sets where precise alignment between upper and lower die shoes is critical. This post is suited for both light-duty and medium-duty press applications where consistent lateral guidance and smooth reciprocating motion are required. Its hardened steel construction makes it appropriate for high-cycle production tooling environments where surface wear and dimensional stability are primary concerns.

Key Features

• Press-fit attachment for secure, tool-free installation into die shoe or mold base bores
• Ball bearing post type provides smooth, low-friction guidance during press stroke
• 1 inch outer diameter for a standard die set fitment
• 3.25 inch overall length suitable for typical die set clearance requirements
• Hardened steel construction resists wear and maintains dimensional accuracy under load
• 5/16-18 thread included for retention or removal during maintenance

Compatibility

Designed as an OEM-style replacement or standard component for press-fit ball bearing guide post applications in metal stamping die sets and mold bases requiring a 1 inch diameter post.

Installation Notes

Installation is performed by tool and die makers using a hydraulic or mechanical press to drive the post into a precision-reamed bore. Ensure the receiving bore is clean and dimensioned to the appropriate press-fit tolerance before installation. Do not hammer the post directly without a proper driver to avoid damaging the ball bearing cage or post surface. Always lock out and tag out the press before servicing die sets.
