Value Collection SC08180481 Arbor Spacer 7/8 Id

Product Description

The VALUE COLLECTION SC08180481 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 7/8 inch inner diameter and a 1-3/8 inch outer diameter, this spacer measures 3/4 inch thick and provides precise, repeatable axial positioning of cutters and other tooling on milling arbors. The hardened and ground finish ensures dimensional consistency and surface integrity under the load conditions typical in machine tool operations. Weighing 0.31 pounds, it is a solid, single-piece component suitable for shop and industrial use.

This arbor spacer is used in milling machine setups where cutters, collars, or other tooling components must be accurately spaced along the arbor shaft. It is a common shop consumable found in tool rooms, maintenance departments, and production machine shops. Machinists and machine tool technicians select these spacers when configuring horizontal or vertical milling arbor assemblies to achieve correct cutter positioning and minimize runout.

Key Features

• Alloy steel construction, hardened and ground for dimensional accuracy
• 7/8 inch inner diameter for standard milling machine arbor fitment
• 1-3/8 inch outer diameter provides adequate bearing surface
• 3/4 inch thickness for precise axial cutter spacing
• Lightweight at 0.31 pounds, easy to handle and stack in multi-spacer setups

Compatibility

Designed for use with milling machine arbors requiring a 7/8 inch bore spacer. Consult your machine tool documentation to confirm arbor diameter and spacer requirements before installation.

Installation Notes

Installation is performed by qualified machinists or machine tool technicians. Always power down and lock out the milling machine before handling arbor components. Inspect the spacer bore and mating arbor surfaces for burrs or contamination before assembly. Stack multiple spacers as needed to achieve the desired cutter position, and ensure all arbor nuts are secured per the machine manufacturer's torque guidelines.
