Value Collection SC08183329 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08183329 is a hardened and ground alloy steel arbor spacer designed for precise positioning on milling machine arbors. With a 1-1/2 inch inner diameter, a 2-1/8 inch outer diameter, and a 1/2 inch thickness, this spacer provides consistent axial spacing between cutters, collars, or other tooling components. The hardened and ground finish ensures flat, parallel faces that maintain tight tolerances during heavy milling operations. Licensed machinists and tool room technicians rely on this type of spacer to set accurate cutter positions and maintain repeatable setups on horizontal and vertical milling arbors.

This arbor spacer is suited for use in production machine shops, tool rooms, and maintenance facilities where milling machine arbor setups require precise spacing. It fits milling machine arbors with a 1-1/2 inch diameter bore. The 1/2 inch face width makes it useful for fine-increment spacing adjustments alongside wider spacers or collars in a stacked arbor assembly. It is sold individually and is compatible with standard arbor setups that require hardened, ground spacers for dimensional accuracy.

Key Features

• Hardened and ground alloy steel construction for flat, parallel faces and tight dimensional tolerances
• 1-1/2 inch inner diameter fits standard milling machine arbors of that bore size
• 2-1/8 inch outer diameter provides adequate bearing surface for stable cutter positioning
• 1/2 inch thickness allows precise axial spacing in stacked arbor cutter assemblies
• Lightweight at 0.25 pounds, minimizing added mass on the arbor

Compatibility

Designed for use with milling machine arbors requiring a 1-1/2 inch bore spacer. Consult your machine tool documentation to confirm arbor diameter and spacer stack requirements before ordering.

Installation Notes

Arbor spacers are installed and removed by qualified machinists following machine tool lockout/tagout procedures — always de-energize and secure the milling machine before handling arbor components. Inspect spacer faces for nicks or burrs before assembly; damaged faces can affect cutter runout and surface finish. Use proper arbor support and draw-in bolt torque per the machine manufacturer specifications. Handle hardened components carefully to avoid edge chipping.
