Steel thrust bearings NTB

high-speedrigid

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 heat-treated 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 high-pressure pumps. These bearings consist of a cage made from a steel plate, which is precisely press formed and surface-hardened, and needle rollers with a diameter variation within 2μm. They have a rigid structure and a high lubricant-retaining 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 high-speed rotations with a low coefficient of friction.
