Combined Type Needle Roller Bearings

In IKO Needle Roller Bearings with Separable Cage, the inner ring, outer ring and IKO needle roller cage are combined, but they can be separated easily. This type has a simple structure with high accuracy. In addition, the radial clearance can be freely selected by choosing an assembly combination. Because they use needle roller cages, these bearings have excellent rotational performance, and are best suited for massproduction, high accuracy products such as machine tools, textile machinery, and printing machines.

IKO Roller Followers are bearings with needle rollers in the thick outer ring that are designed for outer ring rotation. There are separable and nonseparable models, double row cylindrical, and other models available. Roller Followers are widely used as follower bearings for various cam mechanisms and as guide rollers for linear motion in conveying equipment.

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.

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.
