High Throughput Roundness Measurement

New AMETEK Taylor Hobson Surtronic R-Series Roundness Tester Is Suitable for Shop Floor and Inspection Room

WEST CHICAGO, IL—An affordable, high-throughput roundness measuring system robust enough for the shop floor and accurate enough for the inspection room has been introduced by AMETEK Taylor Hobson (

The new Surtronic R-Series Roundness and Form Testers use a proprietary orientation mechanism that allows the operator to easily position a part for measurement in as little as 20 seconds – one third the time required for traditional instruments. Throughput is further enhanced by the fact that there is no need to re-center when measuring a series of similar parts by using the patented centering attachment.

The instruments are designed for measuring high volume bearing parts (including raceway, ball, needle and roller bearings) and for a wide range of quality control applications in automotive, aerospace, optics and process control of grinding, turning, milling and honing.

High throughput is achieved with no loss of precision or accuracy. Full ISO compliant measurements can be taken with ±25 nm accuracy and 6 nm gauge resolution. Results are displayed on the robust touch-screen interface using the intuitive X-sight software delivering ease of use with no operator training required.

Crafted of durable materials, the instruments are designed for dependable 24/7 operation in demanding environments. Modular construction allows easy on-site servicing. A full range of accessories and standards is also available.

Taylor Hobson is a leading manufacturer of ultra-precision measurement instruments for a wide range of markets including optics, semiconductors, manufacturing and nanotechnology research. It is a unit of AMETEK, Inc., a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of more than $3 billion.
