Value Collection SC08180960 Arbor Spacer 2in Alloy Steel

Product Description

The VALUE COLLECTION SC08180960 is a hardened and ground alloy steel machine tool arbor spacer designed for precise axial positioning on milling machine arbors. At 2 inches thick with a 7/8-inch inner diameter and a 1-3/8-inch outer diameter, this spacer provides a rigid, dimensionally consistent interface between cutter assemblies and arbor shoulders. The hardened and ground finish ensures tight tolerances and a flat, burr-free seating surface, which is critical for maintaining cutter runout within acceptable limits during machining operations. Weighing approximately 0.5 pounds, the piece is solid and durable for repeated use in production environments.

This arbor spacer is intended for use on horizontal and universal milling machine arbors where cutters, collars, and other tooling components must be spaced at controlled intervals. It suits tool room, production, and maintenance machining applications. Machine operators and tool room machinists install these spacers when setting up gang milling operations or when repositioning cutters along the arbor to match a required cut location or workpiece geometry.

Key Features

• Hardened and ground alloy steel construction for consistent dimensional accuracy and long service life
• 2-inch thickness provides substantial axial spacing between arbor-mounted cutter assemblies
• 7/8-inch inner diameter fits standard 7/8-inch milling machine arbors
• 1-3/8-inch outer diameter is sized to clear typical arbor nut and support yoke clearances
• Ground faces ensure flat, parallel seating to minimize cutter runout

Compatibility

Designed as an OEM-style spacer for use with milling machine arbors requiring a 7/8-inch bore diameter.

Installation Notes

Installation is performed by machinists or tool room technicians during arbor setup. Always power down and lock out the machine spindle before handling arbor components. Inspect spacer faces for nicks or debris before assembly, as any contamination on the ground surfaces can introduce cutter runout. Follow the machine manufacturer guidelines for arbor nut torque and support yoke positioning.
