Part of THK CO., LTD., THK Niigata Co., Ltd. is a specialized manufacturer of precision mechanical components, primarily focusing on the development and production of ball splines—a key linear motion product originally developed by the THK group. The company is based in Agano, Japan. THK Niigata integrates advanced manufacturing processes across multiple dedicated factories, employing skilled technicians and automation technologies, including IT, IoT, and AI, to ensure high precision, efficiency, and rapid response to customer needs. Ball splines produced by THK Niigata enable smooth, accurate transmission of combined rotational and linear motion with high rigidity, load capacity, and durability. The Japanese company's design, featuring rolling grooves and ball circulation, offers advantages over traditional linear bushes, such as increased contact area, reduced vibration, extended service life, and the ability to support compact, lightweight machinery. The company provides a broad product lineup with spline shaft diameters ranging from 3mm to over 100mm, including hollow shafts for high-speed operation and specialized retainers to reduce friction and heat. Optional features like automatic lubrication devices enhance maintenance intervals and reduce downtime. THK Niigata customizes ball splines for challenging environments, offering metal retainers for high-temperature and vacuum applications, as well as stainless steel, plated, or special alloy variants for corrosion resistance. The company's products are used across industries including semiconductor manufacturing equipment, medical devices, machine tools, robotics, logistics, transportation, electric vehicles, and renewable energy sectors. The company emphasizes low wear, low dust generation suitable for cleanroom environments, and non-magnetic options for strong magnetic fields. THK Niigata holds certifications such as ISO 9001, ISO 14001, and JIS Q 9100, and promotes initiatives related to IoT, AI, and sustainable development goals. The company provides product information, technical support, case studies, and recruitment opportunities to expand applications of ball splines.
