NSK Ltd. has completed the acquisition of the global condition monitoring system (CMS) business known as Brüel & Kjær Vibro (B&K Vibro) from Spectris Plc., in line with the initial announcement made on December 10, 2020.

The acquisition will accelerate development of NSK's business platform in the growing CMS market, and further strengthen the company's ability to respond to demand for automation, labor savings, smart technology, and environmentally sustainable solutions.
