Value Collection SC08183048 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08183048 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 1.5-inch inner diameter and a 2.125-inch outer diameter, this spacer provides precise axial positioning of cutters, collars, and other tooling on standard milling arbors. At 0.0625 inches thick, it is suited for fine-increment spacing adjustments where dimensional accuracy is critical. The hardened and ground finish ensures consistent thickness across the face, which directly affects cutter runout and surface finish quality. Machinists and tool room technicians working in production or maintenance environments will find this spacer a standard consumable for arbor setups.

This arbor spacer is intended for use on horizontal and universal milling machine arbors in machine shop, tool room, and manufacturing environments. It functions as a precision shim between milling cutters, side milling cutters, or gang milling assemblies to achieve correct cutter spacing and lateral positioning. The compact profile and hardened surfaces make it suitable for both light-duty and production-volume milling operations where repeatable setup accuracy is required.

Key Features

• Hardened and ground alloy steel construction for dimensional consistency and wear resistance
• 1.5-inch inner diameter fits standard milling machine arbors of that bore size
• 2.125-inch outer diameter provides adequate bearing surface for cutter and collar contact
• 0.0625-inch thickness allows fine axial spacing adjustments in multi-cutter arbor setups
• Flat, ground faces minimize runout contribution when stacking multiple spacers

Compatibility

Designed as an OEM-style replacement or supplemental spacer for milling machine arbors requiring a 1.5-inch bore and 2.125-inch outer diameter spacer.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Before assembling or disassembling arbor tooling, ensure the machine is powered down, the spindle is locked, and all stored energy has been released per standard lockout/tagout procedures. Stack spacers with clean, burr-free contact faces to minimize cumulative runout. Inspect spacer faces for nicks or raised edges before use, as surface defects will transfer directly to cutter positioning accuracy.
