Value Collection SC08180978 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08180978 is a hardened and ground alloy steel arbor spacer designed for use on milling machine arbors. It features a 7/8 inch inner diameter and a 1-3/8 inch outer diameter, with a 3 inch thickness. The hardened and ground finish provides consistent dimensional accuracy and a precise fit on arbor assemblies. This type of spacer is used to position and separate cutters, collars, or other tooling components at fixed intervals along a milling arbor. Machinists and tool room technicians are the primary installers of this component.

This arbor spacer is suited for use on horizontal and vertical milling machine arbor setups where precise cutter spacing is required. Its 3 inch length makes it appropriate for applications where a longer standoff between tooling components is needed. The hardened and ground alloy steel construction resists wear and maintains dimensional stability under the loads and vibration typical in milling operations. It is a single-piece unit packaged individually.

Key Features

• 7/8 inch inner diameter and 1-3/8 inch outer diameter for standard milling arbor fitment
• 3 inch thickness provides substantial cutter separation along the arbor
• Alloy steel construction with hardened and ground finish for dimensional accuracy and wear resistance
• Designed specifically for milling machine arbor applications
• Single-piece unit, sold individually

Compatibility

Designed for use with milling machine arbors requiring a 7/8 inch bore spacer. Verify arbor diameter, required spacer thickness, and cutter spacing requirements before installation.

Installation Notes

Installation is performed by machinists or tool room technicians during arbor assembly or cutter setup. Power down and lock out the milling machine before handling arbor components. Inspect the arbor bore and spacer bore for burrs or damage before assembly to ensure proper seating. Follow the machine manufacturer guidelines for arbor assembly torque and draw-in bolt procedures.
