The Model B-20 Concentricity Gaging System is a precision inspection platform engineered for accurate measurement of concentricity, runout, and total indicator reading (TIR) on medium diameter cylindrical components.

Designed to bridge the gap between compact and large-capacity systems, the B-20 accommodates parts from 3/8 inch to 2 inches in diameter and up to 6 inches in length.

Its modular construction, adjustable clamping system, and smooth rotation drive provide consistent and repeatable results in both quality laboratories and production environments.

The B-20 is ideal for manufacturers requiring greater diameter flexibility while maintaining bench-top efficiency and high accuracy.

KEY BENEFITS

• Diameter capacity up to 2 inches

• Extended part length capacity up to 6 inches

• Less than 2 micron accuracy under proper setup conditions

• Smooth, constant part rotation

• Adjustable clamping pressure for part stability

• Modular platform for flexible inspection configurations
