Value Collection SC08200032 Arbor Bushing Alloy Steel

Product Description

The VALUE COLLECTION SC08200032 is an alloy steel machine tool arbor bushing designed to adapt bore sizes on milling machine arbors. With a 7/8-inch hole diameter, a 1-7/8-inch outside diameter, and an overall length of 3-1/8 inches, this bushing provides a precise, close-tolerance fit between the arbor and cutting tool assembly. It holds a total indicated runout (TIR) of 0.0004 inches, making it suitable for applications where concentricity and dimensional accuracy are critical. Machinists and toolroom technicians working with horizontal or vertical milling setups rely on arbor bushings like this to maintain proper tool alignment and minimize vibration during cutting operations.

This arbor bushing is intended for use with milling machine arbors in shop and toolroom environments. It is a standard fit for horizontal milling operations where shell mills, side milling cutters, or other arbor-mounted tooling require a bore adapter to match the arbor shaft diameter. At 1.94 pounds, the bushing is machined from alloy steel to provide the strength and wear resistance demanded by continuous production or maintenance machining work.

Key Features

• 7/8-inch hole diameter for precise arbor-to-tool bore adaptation
• 1-7/8-inch outside diameter suits standard arbor support and tooling assemblies
• 3-1/8-inch length provides stable, full-contact engagement along the arbor
• 0.0004-inch TIR ensures tight concentricity for accurate cutting performance
• Alloy steel construction delivers hardness and wear resistance under milling loads

Compatibility

Designed for use with milling machine arbors requiring a 7/8-inch bore bushing. Refer to your arbor and tooling manufacturer specifications to confirm dimensional fit before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the milling machine before installing or removing any arbor components. Inspect the bushing bore and arbor shaft for burrs or damage prior to assembly, and clean mating surfaces thoroughly to maintain the specified runout tolerance. Do not force-fit the bushing; use appropriate arbor press tooling if an interference fit is required.
