Value Collection SC08200123 Arbor Bushing Alloy Steel

Product Description

The VALUE COLLECTION SC08200123 is an alloy steel machine tool arbor bushing designed for use with milling machine arbors. It features a 1-1/4 inch hole diameter, a 2-3/4 inch outside diameter, and a 4-1/4 inch overall length. The bushing holds a total indicated runout (TIR) of 0.0004 inches, making it suitable for precision milling operations where concentricity is critical. Machined from alloy steel, it delivers the strength and wear resistance required in production and job-shop environments. Installation is handled by machinists and toolroom technicians setting up horizontal or vertical milling arbors.

This arbor bushing is used to adapt or support milling machine arbors in toolroom, production machining, and maintenance applications. It fits into setups where the arbor requires a bushing to fill a bore or support a cutting tool assembly. The 4-1/4 inch length provides adequate support for arbor-mounted cutters in both light and moderate-duty milling operations. Typical installations occur in horizontal milling machines where arbor support bushings are standard components of the tooling setup.

Key Features

• 1-1/4 inch hole diameter for precise arbor fitment
• 2-3/4 inch outside diameter for standard arbor support bore compatibility
• 4-1/4 inch length for extended arbor support
• 0.0004 inch TIR for high-concentricity milling applications
• Alloy steel construction for strength and wear resistance

Compatibility

Designed for use with milling machine arbors. Verify hole diameter, outside diameter, and length against your specific arbor and machine specifications before installation.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the milling machine before removing or installing arbor components. Ensure the bushing bore and mating arbor surfaces are clean and free of burrs before assembly to maintain the specified runout tolerance. Handle alloy steel bushings carefully to avoid surface damage that could affect concentricity.
