Value Collection SC08182974 Arbor Spacer 1-1/4 in Id

Product Description

The VALUE COLLECTION SC08182974 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 3 inch thickness, this spacer provides precise axial positioning of cutting tools and accessories on milling arbors. The hardened and ground finish ensures dimensional accuracy and surface integrity under the repeated clamping forces and vibration loads common in machining environments. Machinists, toolroom technicians, and machine tool maintenance professionals install this type of spacer as part of arbor setups on horizontal and vertical milling machines.

This arbor spacer is suited for machine shop environments where accurate cutter spacing is required on milling arbors. It is appropriate for both production floor and toolroom applications. The alloy steel construction and hardened surface resist wear and deformation during extended milling operations. The 3 inch thickness makes it useful when a significant axial gap must be filled between cutters, collars, or other arbor components.

Key Features

• 1-1/4 inch inner diameter for standard milling arbor fitment
• 1-3/4 inch outer diameter provides solid clamping surface contact
• 3 inch thickness fills large axial gaps in arbor setups
• Alloy steel construction for strength and wear resistance
• Hardened and ground finish ensures dimensional precision

Compatibility

Designed for use with milling machine arbors requiring a 1-1/4 inch bore arbor spacer.

Installation Notes

Machinist or machine tool technician installation is typical. Power down and lock out the milling machine before assembling or disassembling arbor components. Inspect mating surfaces for burrs or debris before seating the spacer, as surface contamination can affect runout and cutter alignment. Follow the machine manufacturer's arbor assembly torque and draw-in bolt procedures.
