Value Collection SC08182040 Arbor Spacer 1-1/4 Id 1-3/4 Od

Product Description

The VALUE COLLECTION SC08182040 is a hardened and ground alloy steel arbor spacer used to precisely position or space cutting tools on milling machine arbors. Measuring 1-1/4 inches inside diameter, 1-3/4 inches outside diameter, and 1/16 inches thick, this spacer maintains accurate axial positioning between cutters, arbor collars, and other tooling components. The hardened and ground finish ensures flat, parallel faces that seat firmly without rocking, which is essential when stacking multiple spacers to achieve a specific cutter-to-cutter distance. Machinists and tool-room technicians rely on precision spacers like this to hold tight tolerances during horizontal and vertical milling operations.

This arbor spacer is intended for use with standard milling machine arbors in production, toolroom, and maintenance machining environments. It is well-suited for horizontal milling setups where multiple side-milling cutters, slitting saws, or shell mills must be spaced to a defined dimension along the arbor. The 1/16-inch thickness makes it a fine-increment spacer for applications requiring precise cutter gang spacing or final adjustment when stacking larger spacers and collars.

Key Features

• Hardened and ground alloy steel construction for accurate face parallelism and wear resistance
• 1/16-inch thickness provides fine-increment spacing adjustment on milling arbors
• 1-1/4 inches ID fits standard milling machine arbor diameters
• 1-3/4 inches OD offers adequate bearing surface for stable cutter positioning
• Lightweight at 0.06 pounds, minimizing added mass on precision arbor assemblies

Compatibility

Designed for use with milling machine arbors requiring a 1-1/4-inch bore spacer, consistent with standard horizontal milling arbor tooling setups.

Installation Notes

Installation is performed by qualified machinists during arbor tooling setup. Power down and lock out the milling machine before assembling or disassembling arbor components. Inspect spacer faces and the arbor surface for burrs or contamination before assembly, as any debris between faces will affect cutter positioning accuracy. Torque the arbor nut to the machine manufacturer's specification after final cutter and spacer arrangement is confirmed.
