Roller Bearings（Outer Ring Type：With Retaining Ring Grooves）

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.

Cylindrical Roller Bearing - Single or Double Row

NSK

Cylindrical roller bearings are suitable for applications involving high-speed rotation because the friction between the rolling elements and the flange of the track wheel is small.

Roller Bearing for Sheaves - NAS Series

IKO

IKO Roller Bearings are heavy duty bearings with rollers incorporated in a double row. They are non-separable bearings with a high load rating. They can withstand not only radial loads but axial loads as well, which are supported at the contacts between the shoulders of the inner and outer rings and the end faces of the rollers. They should be used at the fixing side of a shaft. Like needle roller bearings, they are also compact. Roller bearing types include: caged, full complement and the type for sheaves, and they can be selected based on the operating conditions. These bearings are used in heavy-duty machinery such as construction equipment, and industrial machines.
