Value Collection SC00617845 Arbor Spacer 2in Id 2-3/4in Od

Product Description

The VALUE COLLECTION SC00617845 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 provides precise axial positioning of cutters and tooling along an arbor shaft. At 3 inches thick and weighing 2.4 pounds, it is built for the dimensional stability and surface finish tolerances that machine tool applications demand. The hardened and ground construction ensures consistent contact surfaces and tight tolerances, minimizing runout and maintaining cutter alignment during cutting operations.

This arbor spacer is intended for use in milling machine setups where precise cutter spacing is required along a horizontal or vertical arbor. It is a standard component in manual knee mills and similar machine tool configurations. Machinists and tool room technicians use arbor spacers to set cutter-to-cutter distance, control chip clearance, and position tooling relative to the workpiece. This spacer is sold individually and suits both production and job-shop environments.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and durability
• 2-inch inside diameter fits standard milling machine arbor shanks
• 2-3/4-inch outside diameter provides adequate bearing surface and rigidity
• 3-inch thickness for precise axial spacing of milling cutters
• Ground surfaces minimize runout and ensure consistent cutter alignment

Compatibility

Designed for use with milling machine arbors. Verify inside diameter, outside diameter, and thickness against your arbor and cutter specifications before installation.

Installation Notes

Arbor spacers are typically installed by a machinist or tool room technician during cutter setup. Always power down and lock out the machine spindle before mounting or removing arbor components. Inspect spacer faces for burrs or contamination before assembly, as surface irregularities can introduce runout. Follow the machine manufacturer's arbor nut torque and draw-in bolt procedures appropriate for your specific machine.
