Product Description

The Single Direction Thrust Ball Bearings of KOMEL Company are composed of three parts: the housing washer, the shaft washer, and the ball and cage assembly. The part that cooperates with the shaft is called the shaft washer, and the part that cooperates with the housing is called the housing washer. The balls roll between the shaft washer and the housing washer. Single Direction Thrust Ball Bearing is used to maintain the position of the balls to prevent them from colliding with and rubbing against each other. These bearings can bear a single-direction axial load and can only limit the axial displacement of the shaft and the housing in one direction. They have a wide range of application fields and are mainly used in crane hooks, vertical water pumps, vertical centrifuges, jacks, and low-speed reducers.

Suffixes

1.Accuracy Classes

P0: Ordinary tolerance, which is the most commonly used tolerance grade for thrust ball bearings. It is suitable for general industrial application scenarios and is used in most ordinary mechanical equipment to meet basic accuracy requirements.

P6: One level higher than P0, usually used for equipment with certain requirements for rotation accuracy, such as the feed system of machine tools, etc., which can make the operation of the equipment more stable and reduce vibration and noise.

P5: The accuracy is higher than P6, and is often used in high-precision mechanical equipment, such as the spindle of precision machine tools, measuring instruments, etc., which can ensure the high-precision operation of the equipment.

2.Clearance Classes

C1: Indicates that the radial clearance of the bearing is smaller than the ordinary group, which is suitable for occasions with strict requirements on clearance and close fit, such as some high-precision spindle systems.

C2: The clearance is smaller than the ordinary group, but larger than the C1 group, and is used in some application scenarios with certain restrictions on clearance, but not as strict as C1.

C3: The clearance is larger than the ordinary group. It is often used in situations where the bearing will change greatly in size due to the increase in temperature during operation. It can avoid the bearing from getting stuck due to thermal expansion.

3. Cage Materials

M: Indicates that the cage material is brass. Brass cages have good strength and wear resistance and are suitable for working conditions with high speeds and medium loads.

F: Indicates steel solid cages, rolling element guided

TN: Usually indicates nylon cages. Nylon cages are light in weight, good in self-lubrication, and low in noise. They are suitable for high-speed thrust ball bearings.

Application

Crane hook: When the crane lifts heavy objects, the hook is subjected to a large axial tensile force. The thrust ball bearing can ensure the axial positioning and rotation flexibility of the hook.

Vertical water pump: The shaft of the vertical water pump is mainly subjected to axial force during operation. The thrust ball bearing can support the weight of the shaft and withstand the axial thrust generated by the impeller.

Vertical centrifuge: It is used to separate solid particles in liquid or liquids of different densities. Its shaft is subjected to a large axial load when rotating at high speed. The thrust ball bearing can ensure the stable operation of the shaft.

Jack: When lifting heavy objects, the jack needs to withstand huge axial pressure. The thrust ball bearing can make the lifting action of the jack more stable and can withstand axial load.

Low-speed reducer: In some low-speed transmission devices that need to reduce the speed and increase the torque, the thrust ball bearing can withstand the axial force and ensure the smoothness of the transmission.
