IKO (Nippon Thompson Co.) was founded in 1950 in Tokyo, Japan, and specializes in needle roller bearings, linear motion guides, and cam followers. IKO serves machine tool, semiconductor, medical device, and robotics industries requiring compact, high-precision motion components. IKO part numbers follow their own systematic nomenclature — such as TAF, NA, and RNA series designations — that parallel but do not directly match INA/Schaeffler or Torrington needle bearing numbering conventions.
