Value Collection SC08180069 Arbor Spacer 7/8 in Id

Product Description

The VALUE COLLECTION SC08180069 is a hardened and ground alloy steel arbor spacer designed for precise positioning and spacing of cutters, collars, and tooling on milling machine arbors. With a 0.875-inch inner diameter and a 1.375-inch outer diameter, this spacer provides a secure, close-tolerance fit on standard arbors. At 3/32 inch thick and weighing just 0.02 pounds, it is a compact, precision-ground component built to maintain consistent cutter placement during milling operations. Licensed machinists, tool-and-die technicians, and shop maintenance personnel regularly stock these spacers as consumable tooling room hardware.

This arbor spacer is suited for use on horizontal and vertical milling machine arbors in both production and maintenance machine shop environments. The hardened and ground finish ensures flat, parallel faces that resist wear and maintain dimensional accuracy under the clamping forces typical of arbor-style milling setups. It is appropriate for shops running standard arbor tooling that requires precise axial spacing between cutters or supporting collars.

Key Features

• Hardened and ground alloy steel construction for wear resistance and dimensional stability
• 0.875-inch inner diameter fits standard milling machine arbors
• 1.375-inch outer diameter for broad cutter-collar compatibility
• 3/32-inch thickness for fine axial spacing adjustments
• Parallel ground faces for accurate, repeatable cutter positioning
• Lightweight at 0.02 pounds for easy handling and stacking

Compatibility

Designed for use with milling machine arbors requiring a 7/8-inch bore spacer in standard arbor tooling setups.

Installation Notes

Installation is performed by machinists or tool-and-die technicians during arbor tooling assembly. Always de-energize and lock out the machine spindle before handling arbor components. Inspect spacer faces for nicks or burrs prior to installation, as surface irregularities will affect cutter alignment. Stack multiple spacers only when combined thickness matches the required axial dimension for the cutter layout.
