IKO Roller Bearings are heavy duty bearings with rollers incorporated in a double row. They are nonseparable 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 heavyduty machinery such as construction equipment, and industrial machines.

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.

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.

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.

IKO's Extended Life Specification Machined Type Needle Roller Bearings are treated with a newly developed special heat treatment that enhances the bearing's surface hardness and toughness, and suppresses the generation and growth of damage on the surface. Significant life extension can be achieved under high load or under the condition of lubrication contaminated with foreign substances. In a life comparison test, IKO's special heat treated Extended Life Series products lasted 5 times longer than standard heattreated products.

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 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.

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.

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.

Slim Type Crossed Roller Bearings are slim bearings having a small outside diameter against the bore diameter and a narrow width. In addition, types with cage, types with separator, and full complement types are available, which can be selected according to the intended use. Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings. The orthogonal array of rollers allows the bearing to handle complex loads simultaneously from any direction, which makes assembly possible without needing to worry about load direction.

The Mounting Holed Type High Rigidity Crossed Roller Bearing has an integral structure (nonsplit) for both the inner and outer rings, with mounting holes that allows it to be easily attached to equipment. Further it is less subject to peripheral structures such as housing or pressure plate and realizes high rigidity and highaccuracy guidance. Rollers are arranged by intersecting orthogonally between inner ring and outer ring of the single structure. A separator, which can smoothly rotate rollers, is incorporated between rollers. The mounting holes in both inner and outer rings facilitate installation to your equipment. An open type and a sealed type are available. The sealed type incorporates special synthetic rubber sealing.

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.

Our CLube technology maintains the lubrication performance for an extended period of time, reducing lubrication schedules and the time it takes to manage them.

IKO Machined Type Needle Roller Bearings are bearings with a low cross sectional height and large load ratings. The outer ring has stable, high rigidity and can be used even for light alloy housings. These bearings are available in metric series and inch series, both of which include a caged type and full complement type. They are suitable for a wide range of conditions including heavy load with either highspeed or lowspeed rotation. In addition, bearings are available with or without an inner ring. The type without an inner ring uses a shaft as the raceway surface, making the design compact.

The outer ring of the Standard Type Crossed Roller Bearings is made of two split pieces, which are bolted together to prevent separation during transportation or mounting, enabling easy handling. These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy.

IKO Spherical Bushings are compact selfaligning spherical bushings with inner and outer rings in contact with the sphere, which can support a large radial load and a bidirectional axial load at the same time. There are many models of Spherical Bushings, but they are basically divided into steelonsteel types and maintenancefree types according to the kind of sliding surfaces. Steelonsteel Spherical Bushings have inner and outer rings of highcarbon chromium bearing steel, of which sliding surfaces are phosphatetreated and then drycoated with molybdenum disulfide (MoS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity. They are especially suitable for applications where there are alternate loads and shock loads. They have wide applications mainly in industrial and construction machinery. Maintenancefree Spherical Bushings consist of an outer ring which has a special PTFE liner reinforced

The IKO Super Flexible Nozzle is a compact nozzle used on machine tools to supply and spray cutting oil exactly at a specified location. Since the angle of the nozzle can be easily changed, the oil supply can be concentrated on the working area, and cooling and lubrication can be performed effectively. As a result, cutting resistance is reduced and superior finish is obtained, achieving high machining accuracy. The tool life can also be extended, which can result in cost savings. The Super Flexible Nozzle can be used at the spindle end of machining centers and at the tool holder of an NC lathe.
