Dayton Lamina 5-0817-826 Ball Bearing Guide Post 1 in Od

Product Description

The DAYTON LAMINA 5-0817-826 is a demountable ball bearing guide post used in precision die sets and mold bases to maintain accurate alignment between upper and lower die components. With a 1 inch outer diameter and an overall length of 5-7/16 inches, this post is manufactured from hardened steel for wear resistance and long service life. A 1-5/16 inch collar OD positions the post at installation, with 1-3/16 inches of post length extending above the collar into the working zone. Mounting hardware, including clamps and screws, is included. This component is installed and serviced by tool and die makers and precision metalworking professionals.

This guide post is suited for use in stamping dies, progressive dies, and mold base assemblies where repeatable, accurate alignment is required. The demountable design allows field replacement without scrapping the die set, making it a practical choice for maintenance and repair operations in industrial toolrooms and production environments. The 5/16-18 thread and press fit length of 4-1/4 inches allow secure retention in the die shoe.

Installation Notes

Installation and replacement should be performed by qualified tool and die makers or machining professionals.

Ensure the die set is fully de-energized and removed from the press before servicing guide posts. Verify bore diameter and press fit length compatibility with the existing die shoe before installation.
