Value Collection SC08183972 Arbor Spacer 1-1/2 in Id

Product Description

The VALUE COLLECTION SC08183972 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 inch thickness, this spacer provides precise positioning of cutters and other tooling components along a milling arbor. The hardened and ground finish delivers tight dimensional tolerances, ensuring accurate and repeatable cutter placement during machining operations. Weighing 1.4 pounds, this is a solid, durable component built for shop-floor conditions.

This arbor spacer is used in horizontal and universal milling machine setups where cutter-to-cutter or cutter-to-support spacing must be maintained accurately. It is typically installed by machinists and tool-room technicians as part of arbor assembly when configuring gang milling setups or spacing side milling cutters. The 3 inch thickness makes it suited to applications requiring a significant standoff between tooling components on the arbor.

Key Features

• Hardened and ground alloy steel construction for tight dimensional tolerances
• 1-1/2 inch inner diameter fits standard milling machine arbors
• 2-1/8 inch outer diameter provides adequate clearance in typical arbor configurations
• 3 inch thickness suits applications requiring substantial cutter spacing
• Ground finish ensures flat, parallel faces for accurate cutter positioning

Compatibility

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

Installation Notes

Arbor spacers are installed by machinists during milling arbor assembly. Power down and lock out the machine spindle before assembling or disassembling any arbor components. Inspect spacer faces and bore for burrs or contamination before installation, as surface irregularities will affect cutter runout and positioning accuracy. Follow the machine manufacturer guidelines for arbor nut torque and support bearing setup.
