Value Collection SC08180564 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08180564 is a hardened and ground alloy steel arbor spacer designed for precise positioning and spacing of cutting tools on milling machine arbors. With a 7/8 inch inner diameter, a 1-3/8 inch outer diameter, and a 7/8 inch thickness, this spacer delivers accurate axial control between cutters, collars, and arbor components. The hardened and ground finish ensures consistent face-to-face contact and tight dimensional tolerance, which is essential for maintaining cutter alignment during milling operations. Machine shop technicians and tool room professionals install this type of spacer as part of routine arbor setup and cutter spacing tasks.

This arbor spacer is suited for horizontal and vertical milling machine setups where multiple cutters or collars must be precisely spaced along an arbor. It is intended for use with standard milling machine arbors that accept 7/8 inch bore tooling. The alloy steel construction and hardened ground surfaces make it appropriate for production environments where repeated use and dimensional consistency are required. It ships as a single-piece unit and is cataloged for individual replacement or supplemental addition to an existing spacer set.

Key Features

• Hardened and ground alloy steel construction for consistent dimensional accuracy
• 7/8 inch inner diameter fits standard milling machine arbors
• 1-3/8 inch outer diameter provides adequate bearing surface for cutter spacing
• 7/8 inch thickness allows precise axial positioning of arbor-mounted cutters
• Ground faces ensure flat, parallel contact with adjacent arbor components

Compatibility

Designed for use with milling machine arbors requiring a 7/8 inch bore arbor spacer. Specific machine compatibility depends on arbor diameter and configuration at the installation site.

Installation Notes

Installation is typically performed by a machinist or tool room technician as part of arbor assembly or cutter changeover. Power down and lock out the milling machine spindle before handling arbor components. Inspect spacer faces for burrs or contamination before assembly to ensure proper seating against adjacent collars and cutters. Handle hardened ground components carefully to avoid nicking the precision-ground faces.
