Cylindrical roller thrust bearings - Import export

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.

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.

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.

We offer our KIS cylindrical roller bearings in various designs and sizes. In addition to the number of roller rows and the design of the cage, the flanges on the inner and outer rings are also considered. Due to their low friction and high rigidity, our cylindrical roller bearings are the perfect, durable solution for applications with high radial loads. They can also compensate for axial displacements (e.g. due to thermal expansion) and are available in sealed designs. Sealed cylindrical roller bearings are protected from dirt, water and dust. The seal prevents the ingress of contaminants and keeps the lubricant in the bearing. Together with you, we will be happy to develop a customised KIS solution for your requirements.

We supply thrust bearings (bearing plates, end thrust bearing), rolling bearing (combined type) and support bearings (plain journal bearings) made of the following material: tungsten carbide (WC); silicon carbide (SiC), VK8 alloy, etc.
