Single Direction Thrust Ceramic Ball Bearing

KOMEL Company high quality Single Direction Thrust Ceramic Ball Bearings are made up of shafts, shafts, sleeves and shaft groups. Seat rings are usually attached to a fixed part of the engine, while shaft rings are used to attach rotating shafts. The seat ring race and shaft ring are designed so that they are suitable for moving the ceramic ball to effectively resist vibration.

Our products have a good price advantage and we have exported our bearings to many markets. We look forward to become your long-term partner in China.

The seat ring and shaft ring materials can be ductile steel, or ceramic materials that can be manufactured according to specific performance criteria to further improve bearing performance, such as high friction, friction, and so on.

These bearings have characteristics such as high performance, load-bearing capacity, toughness, and corrosion resistance, and are widely used in fields such as mechanical engineering, automotive, chemical equipment, aerospace, and medical 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

Machine Tool Industry: In the spindle system of machine tools, single direction thrust ceramic ball bearings can be used to bear axial loads, ensuring the axial positioning accuracy and stability of the spindle, and improving the machining accuracy and efficiency of the machine tool. For example, they are widely used in equipment such as precision grinders and boring machines.

Motor Industry: In motor products such as high-speed motors and servo motors, single direction thrust ceramic ball bearings can adapt to the high-speed operation of the motors, bear axial loads. Meanwhile, their low friction and electrical insulation properties help to improve the efficiency and reliability of the motors.

Chemical Equipment: Due to the presence of a large number of corrosive media in the chemical production environment, the corrosion resistance of single direction thrust ceramic ball bearings makes them an ideal choice for bearings in chemical equipment. For instance, in equipment such as pumps and compressors, they can ensure the normal operation of the equipment and reduce failures caused by bearing corrosion.

AerXspace: In the aerospace field, the requirements for the performance and reliability of bearings are extremely high. The characteristics of single direction thrust ceramic ball bearings, such as low density, high performance, and corrosion resistance, enable them to meet the needs of key components such as aircraft engines and aircraft landing gears, ensuring the safe operation of the equipment.

Medical Devices: In some medical devices, such as the rotating components of dental hand pieces and CT scanners, bearings with high precision, low noise, and no pollution are required. The low friction, high cleanliness, and corrosion resistance of single direction thrust ceramic ball bearings can meet the special requirements of medical devices, ensuring the normal operation of the equipment and the safety of patients.
