Value Collection SC08181083 Arbor Spacer 1in Id 1.5in Od

Product Description

The VALUE COLLECTION SC08181083 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. It measures 1 inch inside diameter, 1-1/2 inches outside diameter, and 1/8 inch thick. The hardened and ground finish ensures precise, consistent thickness for accurate tool positioning and minimal runout. Machinists and tool room technicians use these spacers to set correct cutter spacing or stack multiple spacers to achieve a required axial position on an arbor. The alloy steel construction provides the rigidity and wear resistance expected in production and toolroom environments.

This arbor spacer is suited for horizontal and vertical milling machine setups where standard arbor tooling is used. It is typically installed between milling cutters, collars, or other arbor-mounted tooling to establish precise lateral positioning. Shops running gang milling operations or setting up multi-cutter arbor assemblies commonly stock multiple spacers of this size. The 1 inch bore fits standard 1 inch diameter milling arbors used in knee mills and horizontal mill setups common in production and job shop environments.

Key Features

• Hardened and ground alloy steel for precise thickness and long service life
• 1 inch inside diameter fits standard 1 inch milling arbors
• 1-1/2 inch outside diameter provides adequate bearing surface between cutters and collars
• 1/8 inch thickness for fine axial spacing adjustments on arbor setups
• Stackable with identical spacers to build up custom spacing increments

Compatibility

Designed for use with milling machine arbors requiring a 1 inch bore spacer. Suitable for horizontal and vertical milling applications where 1 inch arbor tooling is installed.

Installation Notes

Installation is performed by machinists or tool room technicians during arbor assembly. Power down and lock out the milling machine spindle before assembling or disassembling arbor tooling. Slide the spacer onto the arbor in the correct sequence between cutters and collars, then secure the arbor nut to the manufacturer-specified procedure. Inspect spacer faces for burrs or contamination before installation to maintain accurate cutter positioning.
