KOYO Bearings

Koyo is the JTEKT Corporation brand for bearings. JTEKT engineering and manufacturing capabilities range from super large bearings with outer diameters of seven meters to miniature bearings with inner diameters as small as one millimeter.

Koyo offers general purpose ball bearings & roller bearings, bearings for extreme temperatures & environments, machine tools, industrial equipment and more. A full list of Koyo bearing applications can be seen here. National Precision Bearings stocks and services the complete line of Koyo bearings and specializes in Koyo needle bearings, Koyo cylindrical track roller and yoke roller bearings, as well as standard ball bearings.Koyo Cylindrical roller bearings have line contact between the rollers and raceway, therefore radial load capability is high, making this bearing superior in regards to its ability to withstand heavy loads and impact loads. Moreover, mounting and removing is easy due to the inner ring and outer ring being separable.
