From its Plymouth headquarters, Interlube employs 90 people and generated $13.1 million in 2012 revenue; it produces lubrication systems for commercial vehicles, construction, mining and heavy and industries, with operations in Ohio and a joint venture on mainland China. The purchase includes Cheltenham-based MSP Distributors Ltd., which was acquired by Interlube in 2007. Timken’s “global reach will provide enhanced investment in the Plymouth facility,” said Interlube Managing Director Mike Cusack.
