Thrust Needle Roller Bearing (NTB)

• 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 2micrometer.
• 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.
• Specially designed thin inner rings (WS) and outer rings (GS), and especially thin (1 mm thick) thrust washers (AS), are available for use in various applications.
• These bearings are generally used by utilizing their inner surface as the guide surface.

About Thrust Bearing

• Thrust Bearings consist of the precisely made cage and rollers and can receive axial loads.
• They have high rigidity and high load capacities and can be used in small spaces.
• Thrust Needle Roller Bearings use needle rollers, while Thrust Roller Bearings use cylindrical rollers.

About Structure and Features

• Thrust Bearings consist of precisely made cage and rollers. They have high rigidity and high load capacities and can be used in small spaces.
• Thrust Needle Roller Bearings incorporate needle rollers, while Thrust Roller Bearings incorporate cylindrical rollers.
• Various types of raceway rings are available, and suitable bearings can be selected according to the operating conditions.
• When the bearing mounting surfaces of a machine are heat-treated and finished by grinding as raceways,
• Thrust Bearings can be used without raceway rings allowing the machine to be made more compact.
• They are most suited to applications where high accuracy is required at high speeds and under fluctuating heavy loads, such as driving mechanisms for automobiles, machine tools, and high-pressure pumps.
