Value Collection SC08183204 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08183204 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 inner diameter and a 2-1/8-inch outer diameter, this spacer provides reliable standoff between cutters, collars, and other arbor-mounted components. The 5/16-inch thickness makes it suitable for fine incremental spacing adjustments during setup. Weighing 0.14 pounds, it is a compact, solid component machined to close tolerances. It is typically installed by machinists and tool room technicians working on horizontal or vertical milling operations.

This arbor spacer is used on milling machine arbors where consistent cutter spacing is required. It is well suited to production machining environments as well as job shop and tool room settings. The hardened and ground finish ensures flat, parallel faces that maintain accurate cutter positioning and minimize runout. This spacer ships as a single unit and is a direct fit for standard arbor setups requiring a 1-1/2-inch bore.

Key Features

• 1-1/2-inch inner diameter fits standard milling machine arbors
• 2-1/8-inch outer diameter provides adequate clamping surface
• 5/16-inch thickness for incremental axial spacing
• Alloy steel construction with hardened and ground finish for flatness and durability
• Lightweight at 0.14 pounds for easy handling during setup

Compatibility

Designed for use with milling machine arbors requiring a 1-1/2-inch bore spacer. Verify arbor diameter and required spacer thickness before installation.

Installation Notes

Installation is typically performed by a machinist or tool room technician during arbor setup. Power down and lock out the machine spindle before placing or removing spacers from the arbor. Ensure arbor nut, spacers, and cutters are free of chips and burrs before assembly to maintain proper face contact and minimize runout. Follow the machine manufacturer's torque and assembly specifications for the arbor nut.
