Value Collection SC00617761 Arbor Spacer 2in Id

Product Description

The VALUE COLLECTION SC00617761 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 2-inch inside diameter and a 2-3/4-inch outside diameter, this spacer measures 1/2 inch thick and weighs 0.3 pounds. It provides precise axial positioning of cutters, collars, and other tooling components along a milling arbor. The hardened and ground finish ensures consistent dimensional accuracy and surface quality, which is critical for maintaining cutter alignment and minimizing runout during milling operations. This is a utility-grade precision spacer suited for machine shop environments and toolroom applications.

This arbor spacer is used in horizontal and universal milling machine setups where cutters must be spaced or positioned at specific intervals along the arbor. It is a common consumable in production machine shops, toolrooms, and maintenance departments that run milling arbors with multiple cutter configurations. Licensed machinists and CNC setup technicians routinely use spacers of this type when building arbor assemblies for face milling, slab milling, and gang milling operations.

Key Features

• Hardened and ground alloy steel construction for dimensional consistency and wear resistance
• 2-inch inside diameter sized for standard milling machine arbors
• 2-3/4-inch outside diameter provides adequate bearing surface for cutter and collar seating
• 1/2-inch thickness allows precise axial positioning of tooling along the arbor
• Ground surfaces minimize runout and support accurate cutter alignment

Compatibility

Designed for use with milling machine arbors requiring a 2-inch bore spacer. Verify arbor diameter, spacer thickness stack, and keyway requirements before assembly.

Installation Notes

Installation is performed by machinists during arbor assembly or cutter changeover on horizontal or universal milling machines. Power down and lock out the machine spindle before handling arbor components. Inspect the arbor, spacer bore, and mating surfaces for burrs or contamination before assembly, as surface defects will affect cutter alignment. Handle hardened components carefully to avoid edge chipping, which can compromise fit and runout performance.
