Value Collection SC08182081 Arbor Spacer 1-1/4 in Id

Product Description

The VALUE COLLECTION SC08182081 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. Measuring 1-1/4 inches inner diameter, 1-3/4 inches outer diameter, and 1/8 inches thick, this spacer provides precise axial positioning of cutting tools and arbor components. The hardened and ground finish ensures dimensional accuracy and surface integrity under the load and vibration conditions common in machining environments. At 0.12 pounds, it is a compact, single-piece component suited for shop floor and production use by machinists and tool room technicians.

This arbor spacer is used in milling machine setups where controlled spacing between cutters, collars, or arbor components is required. It is appropriate for both manual knee mills and horizontal milling arbor assemblies where consistent tool positioning and rigid cutter support are critical. The 1/8-inch thickness makes it a standard shim-style spacer for fine axial adjustments in multi-cutter arbor configurations common in production and job shop environments.

Key Features

• Hardened and ground alloy steel construction for dimensional precision and wear resistance
• 1-1/4 inches inner diameter fits standard milling machine arbors
• 1-3/4 inches outer diameter provides adequate clamping surface
• 1/8 inches thickness for fine axial spacing adjustments
• Lightweight at 0.12 pounds for easy handling and tool setup

Compatibility

Designed for use with milling machine arbors as an OEM-style spacing component for axial cutter positioning applications.

Installation Notes

Installation is performed by machinists or tool room technicians during arbor assembly or cutter setup. Power down and lock out the machine spindle before servicing the arbor or adjusting spacer positions. Ensure mating surfaces are clean and free of burrs before seating the spacer to maintain squareness and prevent runout. Follow the machine manufacturer's arbor assembly torque and draw-bar procedures.
