Value Collection SC08200131 Arbor Bushing Alloy Steel

Product Description

The VALUE COLLECTION SC08200131 is an alloy steel arbor bushing designed to reduce or adapt the bore of milling machine arbors. The bushing features a 1.5-inch hole diameter, a 2.75-inch outside diameter, and a 4.25-inch overall length. Manufactured from alloy steel, it delivers the hardness and wear resistance required for sustained use in precision machining environments. A total indicated runout (TIR) of 0.0004 inches makes this bushing suitable for applications where concentricity and minimal vibration are critical. Licensed machinists and toolroom technicians typically install and service this type of component.

This arbor bushing is intended for use with milling machine arbors in toolroom and production machining setups. It is suited for horizontal milling machines where the arbor bore must be adapted to match a specific cutter or toolholder bore size. The 1.5-inch bore and 2.75-inch OD sizing accommodates standard arbor configurations found in both manual and CNC milling applications. Its alloy steel construction holds up under the rotational loads and cutting forces typical of milling operations.

Key Features

• 1.5-inch hole diameter for precise bore adaptation on milling arbors
• 2.75-inch outside diameter for a secure fit within standard arbor bores
• 4.25-inch length provides extended engagement and stability
• 0.0004-inch TIR ensures high concentricity and reduced runout during cutting
• Alloy steel construction resists wear and deformation under machining loads

Compatibility

Designed for use with milling machine arbors as stated by the manufacturer. No additional specific model or system compatibility data was provided in the product input.

Installation Notes

Installation and removal of arbor bushings should be performed by a qualified machinist with the spindle fully de-energized and the machine locked out per applicable safety procedures. Inspect the arbor bore and bushing OD for burrs or surface damage before pressing or sliding the bushing into place. Proper seating is critical to maintaining the rated TIR; do not force the bushing with impact tools that could distort the bore or scoring surfaces.
