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.

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.

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'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.

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.

IKO Needle Roller Cages for Engine Connecting Rods are bearings for use in engine connecting rods. These bearings have superior performance proven in high performance engines of racing motor cycles, and are widely used in small motor vehicles, motor cycles, outboard marines, snow mobiles, highspeed compressors, etc. and also in generalpurpose engines. Bearings for engine connecting rods are used under extremely severe and complex operating conditions such as heavy shock loads, high speeds, high temperatures and stringent lubrication. Needle Roller Cages for Engine Connecting Rods are lightweight, and have high load ratings and high rigidity as well as superior wear resistance to withstand severe conditions.
