Roller Bearings（Number of Raceway Ring Rows：Single Track）

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.

Tapered Roller Bearing - Single Row

NTN

Tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.

NTN’s pioneering efforts in developing crowned rollers have resulted in greater load-carrying capability and longer bearing life. Crowned rollers under load distribute stress equally along their full length of contact with the raceways, thereby eliminating stress concentration at the roller ends. This design concept also compensates for minor misalignment between shaft and housing bore and deflection under load, thereby reducing stress concentration.

Needle Roller Bearing - Shell Type, TA Series

IKO

IKO Machined Type Needle Roller Bearings have an outer ring made by machining, heat treatment, and grinding. The outer ring has stable high rigidity and can be easily 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.

IKO - Shell Type Needle Roller Bearing - Standard - TLA Type (IKO)

IKO

Shell Type Needle Roller Bearings are lightweight bearings with large load ratings. They employ a shell type outer ring made from a thin special-steel plate which is accurately drawn, carburized and quenched, thus providing the lowest sectional height among the needle roller bearings.

There are two types of bearings available in this series; the caged type and the full complement type. The appropriate type can be selected according to the operating conditions. The caged type has a structure in which the needle rollers are accurately guided by the cage and thrust rings. It is useful for applications at high-speed rotation. The full complement type needle roller bearing, on the other hand, is suitable for heavy-load applications at low-speed rotation.

Since these bearings are press-fitted into the housing, no fixtures for axial positioning are needed. They are ideal for use in mass-produced articles that require economy and have a wide variety of applications.

Needle Roller Bearing - Separable Cage, Inner Ring, NAF 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.

IKO - Needle Roller Bearings With Separable Cage With Inner Ring - NAF Series (IKO)

IKO

In Needle Roller Bearings with Separable Cage, the inner ring, outer ring and Needle Roller Cage are combined, and they can be separated easily. This type has a simple structure with high accuracy. In addition, the radial clearance can be freely chosen by selecting and combining these component parts. As Needle Roller Cages are used, these bearings have excellent rotational performance. These bearings are most suitable for mass-production high accuracy products such as machine tools, textile machinery, and printing machines.

When especially high accuracy is required, it is possible to supply semi-finished inner rings which have a finishing allowance on their outside diameter so that they can be ground after being press-fitted to shafts.

Crossed Roller Bearing - High Rigidity, Mounting Hole, CRBF Series

IKO

IKO Crossed Roller Bearigns are compact bearigns with their rollers alternatively crossed at right angles to each other between inner and outer rings. The rollres make line-contact with raceway surfaces, and, therefore, elastic deformation due to bearing loads is very small. They can take loads from any directions at the same time such as radial, thrust and moment loads. It is possible to make your design compact comparing to the usage of taper roller bearing and combination of two ball bearings. These bearrings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy.
