Value Collection SC08183485 Arbor Spacer 1.5in Id 2.125in Od

Product Description

The VALUE COLLECTION SC08183485 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 1-1/2 inch inner diameter, a 2-1/8 inch outer diameter, and a 3/4 inch thickness, this spacer provides precise positioning and secure axial location of cutters, collars, and other tooling components on arbor setups. The hardened and ground finish ensures consistent dimensional accuracy and resistance to wear under the repetitive loading typical of milling operations. It weighs 0.36 pounds and is sold individually. Machinists, tool-and-die makers, and machine shop technicians are the primary installers.

This arbor spacer is suited for standard milling machine arbor assemblies where precise cutter-to-cutter or cutter-to-collar spacing is required. It is commonly used in horizontal milling setups to position shell end mills, side milling cutters, and straddle milling arrangements. The hardened and ground construction makes it appropriate for production environments where repeated arbor teardowns and reassembly demand consistent stack-up tolerances. It fits milling machine arbors with a 1-1/2 inch bore diameter.

Key Features

• Hardened and ground alloy steel construction for dimensional consistency and wear resistance
• 1-1/2 inch inner diameter for standard milling arbor fitment
• 2-1/8 inch outer diameter provides adequate bearing surface without interfering with cutter geometry
• 3/4 inch thickness allows precise axial positioning in arbor stack-ups
• Lightweight at 0.36 pounds for easy handling during arbor assembly

Compatibility

Designed as an OEM-style replacement and standard-fit spacer for milling machine arbors with a 1-1/2 inch bore diameter.

Installation Notes

Installation is performed by qualified machinists or machine tool technicians. Power down and lock out the milling machine spindle drive before disassembling or assembling any arbor components. Inspect the arbor bore and spacer surfaces for burrs or contamination before stacking components. Follow the machine manufacturer's arbor assembly procedure and torque requirements as specified in the machine documentation.
