Value Collection SC08180820 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08180820 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. It features a 7/8 inch inner diameter and a 1-3/8 inch outer diameter, with a 1-1/2 inch thickness. This spacer is used to set precise axial positioning of cutters and other tooling on arbors in machine tool setups. Installation is typically performed by machinists or toolroom technicians working on horizontal or vertical milling machines. The hardened and ground finish provides consistent dimensional accuracy and wear resistance under repeated use.

This arbor spacer is suited for machine shop environments where accurate cutter spacing is required on milling arbors. The alloy steel construction handles the rigidity demands of production milling operations. It is commonly used in both manual and CNC milling machine setups where tooling must be precisely located along an arbor shaft. Individual spacers can be stacked or combined with other spacers to achieve a required total width between cutters or collars.

Key Features

• 7/8 inch inner diameter fits standard milling arbor shaft sizes
• 1-3/8 inch outer diameter provides adequate bearing surface for cutter support
• 1-1/2 inch thickness for precise axial spacing of milling cutters
• Alloy steel construction with hardened and ground finish for dimensional accuracy
• Designed specifically for use with milling machine arbors

Compatibility

Designed as an OEM-style replacement and standard fitment spacer for milling machine arbors requiring a 7/8 inch bore.

Installation Notes

Installation is performed by machinists or toolroom personnel. Power down and lock out the milling machine before handling arbor tooling. Slide the spacer onto the arbor shaft and verify seating against adjacent tooling components before tightening the arbor nut. Inspect the bore and face surfaces for burrs or contamination that could affect spacing accuracy.
