Value Collection SC08183402 Arbor Spacer 1.5in Id

Product Description

The VALUE COLLECTION SC08183402 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. It provides precise axial positioning of cutters, collars, and other tooling components along a milling arbor. The spacer measures 1-1/2 inches inner diameter, 2-1/8 inches outer diameter, and 5/8 inches thick. The hardened and ground finish ensures consistent thickness tolerances and flat, parallel faces — critical for maintaining cutter alignment and minimizing runout during milling operations. Machinists and tool room technicians install this type of spacer as part of standard arbor tooling setups.

This arbor spacer is suited for horizontal and universal milling machine setups where multiple cutters or spacing elements must be positioned on a standard milling arbor. It is commonly used in production machining, tool and die work, and general machine shop environments. The 1-1/2 inch bore accommodates standard arbor diameters, and the 2-1/8 inch outer diameter provides adequate support surface for adjacent tooling components. Sold individually.

Key Features

• Alloy steel construction with hardened and ground surfaces for consistent thickness and parallelism
• 1-1/2 inches inner diameter fits standard milling machine arbors
• 2-1/8 inches outer diameter provides broad cutter-support contact area
• 5/8 inches thickness for precise axial spacing of milling cutters and collars
• Hardened construction resists wear under repeated clamping and machining loads

Compatibility

Designed as an OEM-style replacement or supplemental spacer for milling machine arbors requiring a 1-1/2 inch bore and 2-1/8 inch outer diameter spacer element.

Installation Notes

Installation is performed by qualified machinists or tool room personnel during arbor tooling setup. Ensure the milling machine spindle is fully stopped and locked out before assembling or disassembling arbor tooling. Inspect spacer faces for burrs or contamination before installation — any debris between mating surfaces can introduce runout. Torque arbor nut to machine manufacturer specifications only.
