Hybrid Angular Contact Ceramic Ball Bearing

China KCOMEL hybrid ceramic angular ball bearings consist of a steel inner and outer ring, a rolling element made of clay material, and a plastic or metal casing. The steel handle is durable and strong enough to withstand heavy loads.

Ceramic and steel elements are used in a combination of circular interior and exterior facing ceramic and steel elements. This will not only improve your weight-lifting skills, but also increase your speed and resistance to damage.

Ceramic rolled parts have high strength, low density, excellent corrosion resistance, chemical resistance, and heat resistance. Compared to conventional metal rollers, ceramic rollers are lighter and have a shorter lifespan. At higher speeds, heat losses due to centrifugal force can be effectively reduced, thus improving engine performance.

Coatings typically include industrial plastics (e.g., polytetrafluoroethylene) and metals (e.g., stainless steel). These industrial plastic coatings are lightweight and have a low coefficient of friction, which can significantly reduce exposure. Steel tubes, on the other hand, are long, strong, and durable, making them ideal for high-speed applications.

The contact angles are 15°, 25°, 40°, and so on.

Ceramic angular hybrid ball bearings have the following characteristics: excellent high-speed performance, load, wear, and corrosion resistance. It has many applications such as aerospace, precision machines, high-speed machines, medical devices and semiconductor devices.

Parameter (Specification)

Suffixes

Material Suffix

H: It indicates ceramic balls. For example, 6205 - H represents a deep groove ball bearing of model 6205 with ceramic balls as the rolling elements.

T: It may indicate a cage made of ceramic materials. If it is the combined suffix "HT", it means the bearing has both ceramic balls and a ceramic cage.

Tolerance Grade Suffix

P4: It indicates that the bearing's tolerance grade complies with the ISO 4 - level standard. It belongs to a high - precision grade and is usually used in equipment with high - precision requirements, such as the spindles of precision machine tools.

P5: The tolerance grade complies with the ISO 5 - level standard. Its precision is slightly lower than that of P4, and it is also widely used in some industrial equipment with certain precision requirements.

Clearance Suffix

C3: It indicates that the radial clearance of the bearing is larger than the standard clearance. It is suitable for situations where the bearing will generate significant thermal expansion during operation, preventing the bearing from seizing due to thermal expansion.

C4: The clearance is larger than that of C3. It is often used in high - temperature, high - speed, or high - load working conditions.

CM: It represents the clearance for motors, which is a special clearance range suitable for equipment such as motors with high requirements for vibration and noise.

Sealing Suffix

Z: It indicates that the bearing has a dust cover on one side, which can prevent dust and other impurities from entering the bearing.

ZZ: It means that the bearing has dust covers on both sides.

RS: It indicates that the bearing has a contact - type rubber seal on one side. The sealing effect is good, which can prevent lubricating oil leakage and the intrusion of external impurities, but it will increase a certain friction torque.

2RS: It means that the bearing has contact - type rubber seals on both sides.

Application

Aerospace: In critical components such as aircraft engines, aircraft flight control systems, and landing gears, the requirements for the performance and reliability of bearings are extremely high. Thanks to their low density and high-performance characteristics, hybrid angular contact ceramic ball bearings can meet these stringent requirements, ensure the stable operation of the equipment, and improve the safety and reliability of aerospace equipment.

Precision Machine Tools: Precision machining imposes strict requirements on the precision, rigidity, and high-speed performance of machine tool spindles. These bearings can improve the machining accuracy and efficiency of machine tools, reduce vibration and thermal deformation, and ensure the machining quality. For example, in precision grinders, boring machines and other equipment, hybrid angular contact ceramic ball bearings can provide high-precision rotational motion to meet the needs of precision machining.

High-speed Motors: With the development of motor technology towards high speed and high efficiency, the high-speed and low-friction characteristics of hybrid angular contact ceramic ball bearings make them an ideal choice for high-speed motors. They help to reduce the energy consumption of motors, improve the operational reliability of motors, and extend the service life of motors. They are widely used in products such as servo motors and high-speed spindle motors.

Medical Devices: In medical devices such as CT scanners and MRI equipment, bearings with high precision, low noise, and no pollution are required. The low-friction, high-cleanliness, and corrosion-resistant characteristics of hybrid angular contact ceramic ball bearings can meet the special requirements of medical devices, ensuring the normal operation of the equipment and the safety of patients.

Semiconductor Manufacturing Equipment: During the semiconductor chip manufacturing process, the requirements for the precision and stability of the equipment are extremely high. These bearings can provide high-precision rotational motion. At the same time, their corrosion-resistant and low-pollution characteristics can meet the strict requirements of the semiconductor manufacturing environment, ensuring the smooth progress of the production process. They are widely used in equipment such as lithography machines and wafer cutters.
