Value Collection SC08182826 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08182826 is a hardened and ground alloy steel machine tool arbor spacer used to precisely position and separate cutters on milling machine arbors. With a 1-1/4 inch inner diameter and a 1-3/4 inch outer diameter, it slips over standard arbor shanks and locks cutter assemblies at the correct axial location. At 1-1/2 inches thick, it provides meaningful standoff distance for tooling setups that require exact spacing. The hardened and ground finish ensures tight dimensional tolerances and a flat, parallel seating surface, both critical for accurate, vibration-free milling operations. Machinists and machine tool maintenance technicians install this spacer as part of horizontal and universal milling arbor assemblies.

This arbor spacer is suited for use in production and job-shop machine tool environments. It is designed for milling machine arbors where cutter spacing must be controlled precisely. Typical applications include gang milling setups where multiple cutters are mounted on a single arbor and positioned with spacers to hit required part dimensions. The alloy steel construction with hardened and ground surfaces holds up under the clamping forces and vibration loads of continuous milling operations.

Key Features

• Hardened and ground alloy steel construction for tight dimensional tolerances and long service life
• 1-1/4 inch inner diameter fits standard milling machine arbor shanks
• 1-3/4 inch outer diameter provides adequate bearing surface for cutter and spacer stacking
• 1-1/2 inch thickness delivers precise axial cutter positioning
• Flat, parallel ground faces seat evenly against cutters, collars, and adjacent spacers
• Designed for use with milling machine arbors in horizontal and universal milling setups

Compatibility

Designed for use with milling machine arbors requiring a 1-1/4 inch bore arbor spacer. Verify arbor shank diameter, spacer OD clearance, and stack length before installation.

Installation Notes

Arbor spacers are installed by qualified machinists or machine tool technicians during arbor assembly or cutter changeover. Power down and lock out the milling machine before handling any arbor components. Inspect the spacer faces and bore for burrs or damage before assembly, as surface defects will transfer runout error to the cutter. Follow the machine manufacturer's torque and drawbar tightening procedures for the specific arbor in use.
