These Roller Followers are lubricated with CLube, a thermosetting solidtype lubricant which fills the inner space of the bearing. CLube is lubricant made of a lot of lubrication oil and fine particles of superhigh molecular polyolefin that are solidified by heat treatment. As the bearing rotates, the lubricating oil oozes out onto the raceway surface in proper quantities, maintaining the lubrication performance for a long period of time.

These bearings are full complement type bearings incorporating double rows of full complement cylindrical rollers in the outer ring. They can withstand large radial loads. Additionally, the outer ring is guided by the outer ring shoulder and the end face of the cylindrical rollers to the axial direction.

Stainless steel roller followers have superior corrosion resistance. They are suitable for use in cleanrooms and environments where oil cannot be used or where water might splash.

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.

Separable Roller Followers are assembled by combining an outer ring, inner ring and needle roller cage. They can be separated from one another, so handling is easy. Oil lubrication is also easy, making them suitable for highspeed rotations. Two types are available without inner ring RNAST and with inner ring NAST. The inner ring type includes open, shield, and sealed types.

New concept! Maintenancefree track surface! Track surface doesn't require lubrication over long term use! IKO CLube Unit for Cam Followers is a lubrication part to mount into Cam Followers. Regular lubrication is not required as lubrication oil is supplied onto the outside diameter surface of the cam follower outer ring and track surface. Long term maintenance free track surface achieved.

These bearings are full complement type bearings incorporating double rows of full complement cylindrical rollers in the outer ring, and can withstand large radial loads. Additionally, the outer ring is guided by the outer ring shoulder and the end face of cylindrical rollers to the axial direction.

These bearings are compactly designed, incorporating very thin needle rollers in an outer ring with a small outside diameter relative to the stud diameter. They are used in electronic devices, OA equipment, and small index devices, etc.

These Cam Followers are lubricated with CLube, a thermosetting solidtype lubricant which fills the inner space of the bearing. CLube lubricant is made from lubrication oil and fine particles of superhigh molecular polyolefin that are solidified by heating. As the bearing rotates, the lubricant oozes out onto the raceway surface in proper quantities, maintaining the lubrication performance for a long period of time. Since the lubrication oil inside CLube maintains the lubrication performance for a long time, it reduces annoying lubricating management work.

These bearings have a stepped tapered portion on the stud, making mounting easy by fixing a set screw to the stepped portion thus they are optimal for applications such as pallet change.

As a tapped hole is prepared for the centralized piping on the stud head, this is optimal for applications where centralized oil piping is necessary.

Since the stud is eccentric, it can be aligned by rotation, and can be easily adjusted so that the load distribution on the outer surface of the outer ring is uniform. These are eccentric cam followers with a onepiece stud that can be mounted in the same mounting holes as those for Standard Type Cam Followers. The eccentricity is 0.25 mm to 0.6 mm.

Cam Followers are bearings with a stud incorporating needle rollers in a thick walled outer ring. These bearings are designed for outer ring rotation with superior rotational performance, a low friction coefficient and high load capacity. CFKRE has a structure with hexagon holes at the end of each stud, making it possible to mount from any location. With an eccentric collar, it also enables easy height positioning adjustment by rotating the stud.

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.

In this series, the caged cylindrical rollers, AZK, and the complete bearings, AZ, in which AZK are combined with an inner ring (WS) and an outer ring (GS) are available. The cage has a special precise structure which is highly rigid. The cylindrical rollers are outwardly arranged and guided by the cage with exact precision to enable them to withstand heavy loads, even at high rotation speeds.

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.

These bearings are doublerow, full complement with a low cross sectional height designed for use in sheaves. There are two types, sealed and shield type. They can withstand heavy radial loads and shock loads at comparatively lowspeed rotations, and can also withstand axial loads. It is easy to fix them axially to sheaves using the stop rings of the outer ring. The width of the inner ring is designed to be larger than that of the outer ring, so they require no spacer between sheaves. The structure is stable because the doublerow of rollers can withstand the moment loads caused by rope transition. The surfaces of these bearings are also treated to provide high corrosion resistance.

The cage is made of synthetic resin, which helps reduce the weight of the device in which the needle roller cage is incorporated. In addition, by optimizing the shape of the cage, the number of needle rollers has increased compared to high carbon steel cages of the same diameter, increasing the load capacity.

IKO Needle Roller Cages for General Usage are bearings that provide excellent rotational performance. Their specially shaped cages, with high rigidity and accuracy, precisely guide the needle rollers. Since needle rollers with extremely small dimensional variations in diameter are incorporated and retained in this needle roller cage, they utilize the machining accuracy of the way and are useful in small spaces when combined with shafts and housing bores that are heat treated and accurately ground as raceway surfaces. In addition, since they are lightweight and have high rigidity as well as a large lubricant holding capacity, they can withstand severe operating conditions such as high speed rotation and shock loads, and they are used in a wide range of applications.

IKO Shell Type Needle Roller Bearings are lightweight bearings with large load ratings. They employ a shell type outer ring made from a thin specialsteel 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 highspeed rotation. The full complement type needle roller bearing, on the other hand, is suitable for heavyload applications at lowspeed rotation. Since these bearings are pressfitted into the housing, no axial positioning fixtures are required. They are ideal for use in massproduced articles that require economy, and have a wide variety of applications.
