Product News: Johnson Gage Runout and Concentricity Inspection System

Affordable JCR-1 verifies cylindrical runout or concentricity in manufacturing or inspection applications.

Published: Wednesday, July 29, 2009 - 14:00

(Johnson Gage: Bloomfield, CT) -- Recognized as the industry leader in thread inspection systems and technology, Johnson Gage has introduced the affordably priced Centrax Runout and Concentricity Inspection System for verification of cylindrical runout or concentricity in manufacturing or inspection applications. The new JCR-1 model incorporates precision datum rolls, a unique upper tension roll assembly, and integral axial stop pins to assure proper part staging and absolute gauge accuracy. To accommodate both part-specific and universal applications, the unit features infinitely-adjustable indicator mounting arm with fine-adjustment positioning and variable CMM tee-slot mounting stand.

It's equipped with a belt drive to remove operator influence and simplify operation while increasing gauge reliability and repeatability. Typical applications for the Centrax Runout and Concentricity Inspection System include finished and semifinished fasteners and fittings, screw machine products, and high-precision medical parts.

Additional features include system accuracy of less than 2 µm, adjustable from 0.125 in. through 1.0000 in., available with standard Mitutoyo test indicators or digital test with SPC output, standard adjustable articulated indicator mounting arm, and tee-slot mounting for infinite positioning options. Also featured are adjustable axial stops to simplify part positioning and prevent motion during inspection. Easy-to-read permanent etched scales on mounting stand simplify repeat measurement applications. The unit can be used on optical comparators or other measurement systems with optional fixture base. The JCR-1 can be used for adjustable or part-dedicated configurations. The standard Centrax JCR-1 model is priced at $995.
