Roller Bearings（Outer Ring Type：With Semicircular Groove）

Roller bearings are bearings with cylindrical rolling elements (rollers) placed between inner and outer rings (called races). They are used in a variety of applications such as general machinery, machine tools, motors and reduction drives. The rolling elements used in roller bearings are cylindrical rollers instead of the balls used in ball bearings. Since roller bearings provide more linear support for the load, they are usually used on shafts receiving higher loads. The types of roller bearings available include cylindrical roller bearings and several others. For example, needle roller bearings are more suited to space-saving applications than cylindrical roller bearings. Conical roller bearings can support a radial load and unidirectional axial load at the same time. Self-aligning roller bearings enable the inner race, rolling elements and retainer to rotate in a tilted posture relative to the outer race, making them suited to use in applications such as machinery with highly flexible shafts.

Needle Roller Bearing - With Inner Ring, Machined, NA49 Series

IKO

IKO Machined Type Needle Roller Bearings are bearings with a low sectional height and large load ratings. The outer ring has high rigidity and can easily be used even for light alloy housings. These bearings are available in metric series and inch series, both of which have the caged type and the full complement type. It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations. In addition, there are bearings with and without an inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.

Needle Roller Bearing - Separable Cage, Without Inner Ring, RNAF Series

IKO

In this series, IKO needle roller bearings are combined with thrust roller bearings to receive thrust loads. Their axial load ratings are greater than those of bearings that are combined with thrust ball bearings. Also, plastic deformation of the rolling contact surfaces under load is minimal. Furthermore, the thrust bearing section is finished to high accuracy, and therefore high rotational accuracy is obtained in the case of both vertical and horizontal shafts.

Like the needle roller bearings with thrust ball bearing, this series also includes bearings with a dust cover and bearings with an inner ring.
