Value Collection SC08181828 Arbor Spacer 1in Id 1-1/2in Od

Product Description

The VALUE COLLECTION SC08181828 is a hardened and ground alloy steel arbor spacer designed for precise axial positioning on milling machine arbors. With a 1-inch inside diameter and 1-1/2-inch outside diameter, the spacer slips over standard arbor shanks to set cutter-to-cutter or cutter-to-collar distances with tight dimensional control. The 1-1/2-inch thickness makes it suited for applications where a single spacer needs to fill a substantial gap. Hardening and grinding deliver the surface finish and dimensional accuracy that production milling work demands. At 0.4 pounds, it is lightweight enough to handle easily without sacrificing rigidity in the arbor stack.

This spacer is intended for use on horizontal and vertical milling machine arbors in toolroom, job shop, and production machining environments. Machinists and machine tool operators use arbor spacers to build up cutter assemblies, maintain cutter spacing, and take up unwanted float between collars and cutters. The SC08181828 fits into any arbor stack where a 1-inch bore spacer with a 1-1/2-inch OD is the correct geometry.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and wear resistance
• 1-inch inside diameter fits standard 1-inch milling machine arbors
• 1-1/2-inch outside diameter provides adequate bearing surface for cutter support
• 1-1/2-inch thickness fills larger gaps in arbor cutter assemblies with a single piece
• Lightweight at 0.4 pounds for easy handling during arbor assembly

Compatibility

Designed as an OEM-style replacement and standard tooling component for milling machine arbors requiring a 1-inch bore spacer with a 1-1/2-inch outside diameter.

Installation Notes

Arbor spacers are installed by qualified machinists or machine tool technicians. Power down and lock out the machine before disassembling or building up an arbor cutter stack. Inspect the spacer bore and faces for burrs or nicks before installation, as surface defects will affect runout. Follow the machine manufacturer guidelines for drawbar torque and arbor nut tightening procedures.
