Thrust Roller Bearings

These bearings consist of a cage made from a steel plate, which is precisely press formed and surfacehardened, and needle rollers with a diameter variation within 2μm. They have a rigid structure and a high lubricantretaining capacity. As they have the lowest sectional height compared with other thrust bearings, they can be used instead of conventional thrust washers and can withstand highspeed rotations with a low coefficient of friction.

IKO Thrust Bearings consist of precisely machined cages and rollers. They have high rigidity and high load capacity and can be used in small spaces. Thrust Needle Roller Bearings use needle rollers, while Thrust Roller Bearings use cylindrical rollers. Various types of raceway rings are available, and can be selected according to the operating conditions. When the bearing mounting surface of a machine is heattreated and finished by grinding, Thrust Bearings can be used without raceway rings, making the machine more compact. They are best suited for applications where high accuracy is required at high speeds and under fluctuating heavy loads, such as the drive mechanisms for automobiles, machine tools, and highpressure pumps.

IKO Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing. Caged Needle Roller Bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings. They are compact and very economical, and can be subjected to radial loads and axial loads simultaneously. They are widely used for machine tools, textile machinery, and industrial machinery.

IKO Cam Followers are bearings with a stud that incorporates needle rollers in a thick walled outer ring. These bearings are designed for outer ring rotation and provide superior rotational performance, a low coefficient of friction and high load capacity. In order to effectively increase the loading zone, this bearing is designed to have a smaller radial clearance than general needle roller bearings, so the shock load is lessened and stable long life can be obtained. Since the studs already have threads or steps, they are easy to mount. Cam followers are follower bearings for cam mechanisms and linear motion and have high rigidity and high accuracy. They are used mostly for machine tools, industrial robots, electronic devices, and OA equipment. Stainless steel cam followers have superior corrosion resistance and are suitable for use in cleanrooms and environments where oil cannot be used or where water might splash.
