Value Collection SC08200057 Arbor Bushing Alloy Steel

Product Description

The VALUE COLLECTION SC08200057 is an alloy steel machine tool arbor bushing designed to reduce bore diameter on milling machine arbors, providing a precise fit between the arbor and cutting tool. With a 1-1/4 inch hole diameter, 1-7/8 inch outside diameter, and 3-1/8 inch overall length, this bushing maintains a total indicated runout (TIR) of 0.0004 inch for accurate, vibration-minimized cutting operations. The alloy steel construction resists wear and deformation under the radial and axial loads common in milling applications. Machinists and toolroom technicians working on horizontal or vertical milling setups rely on this type of precision bushing to match arbor and cutter bore sizes.

This arbor bushing is intended for use with milling machine arbors where the cutter bore is larger than the arbor diameter. It is a standard fit in toolroom and production machining environments, both light industrial and heavy manufacturing. Installation requires no specialized equipment beyond a press or mallet and proper arbor tooling. The close-tolerance fit supports repeatable cutter indexing and consistent surface finish results across production runs.

Key Features

• 1-1/4 inch hole diameter for direct fit to standard milling arbor shanks
• 1-7/8 inch outside diameter accommodates larger-bore cutter mounting
• 3-1/8 inch length provides full contact and support along the arbor
• 0.0004 inch TIR for high-precision, low-runout cutter operation
• Alloy steel construction for durability under continuous milling loads

Compatibility

Designed for use with milling machine arbors as an OEM-style precision reducer bushing. Compatible with milling machine arbors where the stated hole and outside diameters match the arbor and cutter bore specifications.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down and lock out the milling machine before installing or removing arbor bushings. Ensure mating surfaces on the arbor and bushing bore are clean and free of burrs before pressing the bushing into position. Do not force-fit a bushing that does not match the arbor diameter, as this can damage the bushing seat and affect runout.
