Value Collection SC08183121 Arbor Spacer Alloy Steel

Product Description

The VALUE COLLECTION SC08183121 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. At 1-1/2 inches inner diameter and 2-1/8 inches outer diameter with a 3/16-inch thickness, this spacer provides precise axial positioning of cutting tools along a milling arbor. The hardened and ground finish ensures tight dimensional tolerances and long service life under the cutting forces typical of horizontal milling operations. Machinists and tool-room technicians use this type of spacer to set cutter-to-cutter spacing or to locate a single cutter at a specific position on the arbor.

This arbor spacer is suited for horizontal milling machine setups where arbor-mounted cutters such as side milling cutters, staggered-tooth cutters, or plain milling cutters need accurate spacing. The 1-1/2-inch bore fits standard milling arbors of that diameter. It is appropriate for production shops, tool rooms, and maintenance environments where close-tolerance spacers are required to maintain consistent cutter positioning across repeat setups.

Key Features

• 1-1/2 inches inner diameter fits standard milling machine arbors
• 2-1/8 inches outer diameter for adequate support surface
• 3/16-inch thickness for precise axial cutter positioning
• Alloy steel construction provides strength and wear resistance
• Hardened and ground finish delivers tight dimensional tolerances

Compatibility

Designed for use with milling machine arbors as an OEM-style spacer for horizontal milling setups requiring a 1-1/2-inch bore arbor spacer.

Installation Notes

Installation is performed by a machinist or toolroom technician during arbor setup. Power down and lock out the milling machine before installing or removing arbor spacers. Ensure all spacers and the arbor bore are clean and free of chips or burrs before assembly to maintain accurate cutter positioning. Torque the arbor nut according to the machine manufacturer specifications.
