Value Collection SC08182966 Arbor Spacer 2in 1-1/4in Id

Product Description

The VALUE COLLECTION SC08182966 is a hardened and ground alloy steel arbor spacer designed for precision positioning on milling machine arbors. At 2 inches thick with a 1-1/4 inch inner diameter and 1-3/4 inch outer diameter, this spacer provides accurate axial spacing between cutters, collars, and other tooling components. The hardened and ground finish ensures consistent dimensional accuracy and surface flatness, both critical in milling setups where runout and cutter positioning directly affect cut quality. Machinists and toolroom technicians use this type of spacer to set cutter spacing or fill arbor length without affecting rigidity or tool alignment.

This arbor spacer is intended for use with standard milling machine arbors in horizontal and universal milling applications. It is suited for toolroom, production, and maintenance environments where repeatable cutter positioning is required. The alloy steel construction and hardened finish make it appropriate for demanding machining conditions where softer spacer materials would deform or wear prematurely. It ships as a single piece and is ready for immediate use without additional preparation.

Key Features

• Hardened and ground alloy steel construction for dimensional consistency and long service life
• 2 inch thickness provides substantial axial spacing for cutter and collar positioning
• 1-1/4 inch inner diameter fits standard milling machine arbor shanks
• 1-3/4 inch outer diameter suits common arbor collar configurations
• Ground surfaces ensure flatness and minimize runout contribution in assembled tooling stacks

Compatibility

Designed for use with milling machine arbors requiring a 1-1/4 inch bore spacer. Verify arbor diameter, spacer stack length, and draw-in bolt clearance before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the milling machine spindle before assembling or disassembling arbor tooling. Inspect arbor, spacers, and collars for burrs or debris before stacking, as contamination on mating faces introduces runout. Torque the draw-in bolt according to the machine manufacturer specifications for the arbor size in use.
