Value Collection SC08200149 Arbor Bushing 2in Hole Alloy Steel

Product Description

The VALUE COLLECTION SC08200149 is an alloy steel machine tool arbor bushing designed to precisely adapt milling machine arbors to spindle or toolholder bores. It features a 2-inch hole diameter, a 2-3/4-inch outside diameter, and measures 4-1/4 inches in length. Manufactured from alloy steel for rigidity and wear resistance, this bushing holds a total indicated runout (TIR) of 0.0004 inches, making it suitable for applications where concentricity and accuracy are critical. Machinists and machine tool technicians install this bushing to achieve a precise fit between arbor and spindle, reducing vibration and maintaining cutting accuracy during milling operations.

This bushing is intended for use with milling machine arbors in machine shop environments, both production and toolroom settings. It is sized for applications requiring a 2-inch bore with a 2-3/4-inch OD interface. The 4-1/4-inch length provides adequate engagement for stable support along the arbor. Typical installations involve horizontal or vertical milling machines where arbor support and runout tolerance are primary concerns. Machine tool technicians and machinists performing arbor setups or spindle tooling changes are the primary installers of this component.

Key Features

• 2-inch hole diameter for direct arbor fitment
• 2-3/4-inch outside diameter for precise bore interface
• 4-1/4-inch length provides stable arbor engagement
• Alloy steel construction for rigidity and long service life
• 0.0004-inch TIR for high concentricity and accurate cutting performance
• Designed for use with milling machine arbors

Compatibility

Designed for use with milling machine arbors requiring a 2-inch bore bushing with a 2-3/4-inch outside diameter.

Installation Notes

Installation is performed by qualified machinists or machine tool technicians. Power down and lock out the milling machine at the main disconnect before handling arbor components. Inspect mating bore and arbor surfaces for burrs or debris before seating the bushing. Handle alloy steel bushings with care to avoid nicking precision ground surfaces, which can affect runout and concentricity.
