The joint ventures were originally set up for the manufacture of sintered-alloy fluid dynamic bearing (FDB) units used in electric motors for hard disk drives. They had been created to assemble FDB units in China and Thailand, respectively, through the establishment of NTN-Nidec (Zhejiang) Corporation in 2002 and NTN-Nidec (Thailand) Co Ltd in 2005. Currently, both joint venture companies are 60% owned by NTN and 40% by Nidec.

The companies said that for ‘profit enhancement’ reasons they decided that FDB-unit assembly lines should be designed and operated in a closer alignment with Nidec's motor assembly operations going forward.
