Value Collection SC08181323 Arbor Spacer 1in Id 1.5in Od

Product Description

The VALUE COLLECTION SC08181323 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. It features a 1 inch inside diameter and a 1-1/2 inch outside diameter, with a 1/2 inch thickness. The hardened and ground finish ensures precise dimensional accuracy and consistent face-to-face contact, which is critical for maintaining accurate cutter positioning on a milling arbor. This type of spacer is a standard component in machine shop setups, used by machinists and tool and die professionals to set axial spacing between milling cutters or to position cutters along the arbor shank.

This arbor spacer is suited for horizontal milling machine setups where multiple cutters or spacing collars are stacked on a standard milling arbor. The 1 inch bore accommodates common arbor shank diameters found in general-purpose and production milling applications. Its compact 1/2 inch width makes it useful for fine axial adjustments when configuring cutter stacks or gang milling arrangements. Sold individually, it integrates directly into existing arbor assemblies without additional modification.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and wear resistance
• 1 inch inside diameter fits standard milling machine arbor shanks
• 1-1/2 inch outside diameter provides adequate bearing surface for cutter stack support
• 1/2 inch thickness allows precise axial cutter positioning on the arbor
• Ground faces ensure flat, parallel seating contact with adjacent spacers or cutters

Compatibility

Designed for use with milling machine arbors requiring a 1 inch bore spacer collar. Suitable for horizontal milling setups using standard arbor configurations where 1 inch ID spacing collars are specified.

Installation Notes

Installation is performed by machinists during arbor assembly and cutter setup on horizontal milling machines. Power down and lock out the machine before assembling or disassembling arbor components. Inspect spacer faces and arbor surfaces for burrs or contamination before assembly, as surface irregularities will affect cutter runout. Stack spacers and cutters in the intended order before seating the arbor nut.
