NTN Open Bearing 6304 C3 20x52x15

NTN started its activity in 1918 when investor Noboru Niwa, his sales company Tomoe Trading Co. and engineer Jiro Nishizono teamed up to design and manufacture the first NTN ball bearings. In 1954 NTN became the first Japanese industrial manufacturer to be awarded the prestigious Deming Prize for Statistical Quality Control. NTN continued to grow as additional factories were built and NTN's sales operations expanded into Europe. Today, NTN operates more than fifty factories worldwide and is the third largest bearing manufacturer in the world.
