Summary: The Timken Company (NYSE: TKR) today announced it has signed an agreement to sell the assets of its Needle Roller Bearings business, which primarily serves customers in the automotive original-equipment sector, to Japan's JTEKT Corporation in a cash transaction.
Roller bearings on the moving platen reportedly reduce friction up to 80% versus a sliding-support design.
Their design is less sensitive to misalignment than traditional roller bearings and contributes to longer service life, higher reliability, and quieter performance, according to the manufacturer.
