Value Collection SC08183642 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08183642 is a hardened and ground alloy steel machine tool arbor spacer designed for precise axial positioning on milling machine arbors. With a 1-1/2 inch inside diameter, a 2-1/8 inch outside diameter, and a 1 inch thickness, this spacer provides consistent, repeatable cutter placement during milling operations. The hardened and ground finish ensures tight dimensional tolerances and long service life under the cyclic loads common in machine shop environments. Machinists and toolroom technicians install this spacer to control cutter spacing, stack multiple cutters, or fill unused arbor length on horizontal milling setups.

This arbor spacer is suited for horizontal milling machine arbors where cutter-to-cutter or cutter-to-support spacing must be maintained accurately. It is a standard shop consumable stocked in toolrooms, maintenance departments, and production machine shops. The 1-1/2 inch bore is the nominal arbor diameter this spacer fits, making it applicable to a wide range of standard milling arbors of that size. It is sold individually and weighs approximately 0.34 pounds.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and wear resistance
• 1 inch thickness provides precise axial cutter positioning on milling arbors
• 1-1/2 inch inside diameter fits standard milling machine arbors of that nominal size
• 2-1/8 inch outside diameter compatible with standard arbor support and cutter stack configurations
• Lightweight at 0.34 pounds — easy to handle and stock in quantity

Compatibility

Designed as an OEM-style replacement or supplemental spacer for use with milling machine arbors having a 1-1/2 inch nominal diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians during arbor cutter setup. Power down and lock out the milling machine before assembling or disassembling the arbor stack. Spacers should be slid onto the arbor in the intended sequence and secured by the arbor nut torqued to the machine manufacturer's specification. Inspect spacer faces for burrs or contamination before assembly to maintain accurate cutter positioning.
