IKO bearing


World Leader in Needle Roller Bearings and Linear Motion Rolling Guides

      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 a pioneer in the Needle Roller Bearing field, the experience and achievements amassed are reflected in the Linear series.

      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. has already developed many products related to the linear motion rolling guide units. Its high quality and superior performance are widely acclaimed. has also gained a reputation as a leader in the manufacturing of linear motion rolling guide units. The linear series has achieved significant growth in several advanced technological industries. One example would be in semiconductor manufacturing equipment where precise positioning is needed.

Needle roller bearings are rotational motion bearings in which a thin needle-shaped roller is incorporated into a rolling element. They have a low cross-section height and high load capacity compared with ball bearings. Being small, needle roller bearings contribute to reducing overall machine size, and are thus widely used in various applications such as automobiles, motorcycles, printing presses, industrial robots and construction equipment.
