Value Collection SC08182321 Arbor Spacer 1-1/4 in Id

Product Description

The VALUE COLLECTION SC08182321 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 1-1/4 inch inner diameter, a 1-3/4 inch outer diameter, and a 1/2 inch thickness, this spacer provides precise axial positioning of cutting tools and accessories on arbors. The hardened and ground finish ensures consistent dimensional accuracy and durability under the repetitive load cycles common in machine tool applications. Machinists and machine tool technicians install this spacer to maintain correct tool spacing and to fill gaps between cutters, collars, and arbor nuts.

This arbor spacer is suited for use on milling machine arbors in both job shop and production machining environments. It is a direct-fit component for horizontal and vertical milling setups where accurate cutter spacing is required. The compact 1/2 inch thickness makes it useful for fine-tuning tool position when standard spacer sets do not provide the exact increment needed. Sold individually, it can be combined with other spacers of varying thickness to achieve the required cutter stack configuration.

Key Features

• Hardened and ground alloy steel construction for dimensional consistency and wear resistance
• 1-1/4 inch inner diameter fits standard milling machine arbors of that bore size
• 1-3/4 inch outer diameter provides adequate bearing surface for cutter and collar contact
• 1/2 inch thickness allows precise axial positioning of milling cutters
• Ground surfaces reduce runout and improve cutter accuracy

Compatibility

Designed for use with milling machine arbors requiring a 1-1/4 inch bore spacer. Suitable for horizontal and vertical milling machine setups where a 1-1/4 inch ID arbor spacer is specified.

Installation Notes

This spacer is installed by licensed machinists or qualified machine tool technicians as part of arbor cutter stack assembly. Power down and de-energize the milling machine before disassembling or assembling arbor components. Ensure all spacers, collars, and cutters are clean and free of burrs before assembly to maintain accurate cutter positioning. Follow the machine manufacturer's torque recommendations for arbor nut tightening.
