Value Collection SC08180408 Arbor Spacer 7/8 Id 1-3/8 Od

Product Description

The VALUE COLLECTION SC08180408 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. It features a 7/8-inch inner diameter and a 1-3/8-inch outer diameter, with a thickness of 5/8 inch. The spacer is manufactured from alloy steel and carries a hardened and ground finish, providing the dimensional stability and surface quality required for precision toolroom and production milling setups. Machinists and tool room technicians install this spacer to set cutter position and maintain correct axial spacing along a milling arbor.

This arbor spacer is intended for use with standard milling machine arbors in both horizontal and vertical milling applications. It is suited for production shops, toolrooms, and maintenance environments where precise cutter spacing is required. The hardened and ground construction ensures consistent stack height when multiple spacers are used together to position face mills, side and face cutters, or other arbor-mounted cutting tools.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and wear resistance
• 7/8-inch inner diameter sized for standard milling arbors
• 1-3/8-inch outer diameter for adequate bearing surface
• 5/8-inch thickness for precise axial cutter positioning
• Designed for use with milling machine arbors per UNSPSC code 27112800

Compatibility

Designed as an OEM-style replacement or standard service spacer for milling machine arbors requiring a 7/8-inch bore.

Installation Notes

Installation is performed by machinists or tool room technicians during arbor setup or cutter changeover. Power down and lock out the milling machine before handling arbor components. Inspect the arbor bore and spacer faces for burrs or debris before assembly to maintain accurate stack height. Stack multiple spacers only when faces are clean and free of nicks to avoid compounded positioning error.
