Nippon Thompson Co., Ltd. is a bearing manufacturer that launched the technical development of needle roller bearings for the first time in Japan and is proud of the high quality level and abundant varieties of its products. Needle roller bearings are bearings for rotary motion that incorporate needleshaped thin rollers instead of ordinary bearing balls or rollers. Compared with other rolling bearings, they are small-sized and lightweight but have a large load capacity. They are widely used with high reliability in the fields of automobiles, industrial machinery, OA equipment, etc. as resource-saving type bearings that make the whole machine compact.
IKO Linear Motion Rolling Guides are used with satisfactory results for various applications requiring precision positioning such as semi-conductor manufacturing equipment, large sized machine tools, industrial robots, and precision equipment. In contrast to conventional rolling bearings used in rotating parts, Linear Motion Rolling Guides are the products applicable to plane sliding surfaces, and meet the increasing needs for linear motion and precision positioning in machines and equipment. Linear Way and Linear Roller Way of Rail Guide Type, Linear Ball Spline of Shaft Guide Type, and other products, recognized for their high quality and excellent features, are available.
IKO Precision Positioning Table is a product brought out from an integration of the linear motion rolling guide technology, which we have developed for many years, and the state-of-the-art technology in microelectronics. IKO Precision Positioning Table is composed of many leading-edge components carefully chosen to meet stringent needs. In the table guiding parts in particular, IKO linear motion rolling guide, which has been well proven in the fields of super precision machines and machine tools, is incorporated to make full use of their high potentials. IKO Precision Positioning Table has proven its excellent performance through a wide range of applications as a positioning mechanism for the state-of-the-art LCD and semiconductor manufacturing facilities such as a variety of measuring equipments, processing machines, and assemblers.

IKO is a brand known for producing high-quality Needle Roller Bearings, Cam Followers, Linear Motion Rolling Guides, and Precision Positioning Stages.

We specialize in crafting top-quality products that meet the highest standards for quality and performance. Our motion devices are designed to deliver precise, accurate results for extended periods with minimal maintenance.

Our knowledgeable engineering team is here to help you find the right solutions for your unique needs. We'll work with you to design and select the right parts, and can even create custom-designed bearings.



IKO was the first company to successfully developed Needle Roller Bearings in Japan, and used that advanced technology as a foundation for entering into the field of Linear Motion Rolling Guides (Linear Way series and Mechatronics series).

We support the advancement of technology with our innovative C-Lube Maintenance Free Series and a wide range of creative products that cater to diverse customer needs.

Long-term maintenance-free running with oil in "C-Lube" only

The innovative capillary lubrication technology using the capillary action (capillarity) is the IKO's original technology. It enables long-term running of products without additional lubricant supply and maintenance. It can greatly contribute to the environment of the earth, either.
