IKO Bearing is famous for their high quality, extremely precise linear motion rolling guides.  IKO's linear motion rolling guides are indispensable for reducing linear motion friction in the positioning mechanisms of machinery.  


IKO was the first company in Japan to initiate technical developments on the Needle Roller Bearing. It is now a leading manufacturer with many remarkable achievements in this field. The Needle Roller Bearing, which encompasses a thin needle-shaped roller has transformed the conventional image of a bearing employing round balls. As compared with the ball bearing and other roller bearings, it is small in size and light, but yet has a great load capacity. Needle Roller Bearings help to make the overall equipment more compact, thus saving money and resources. They are used in a wide range of applications such as motorcycles, industrial machines and office automation equipment where they have proven to be extremely reliable.


As opposed to the standard rotational way of using bearings, the linear series has extended its area of application to level sliding devices. A completely new product to make the linear motion rolling guide units more precise. IKO has already developed many products related to the linear motion rolling guide units. Its high quality and superior performance are widely acclaimed. IKO has also gained a reputation as a leader in the manufacturing of linear motion rolling guide units. The IKO linear series has achieved significant growth in several advanced technological industries. One example would be in semiconductor manufacturing equipment where precise positioning is needed.
