16018 Deep Groove Ball Bearing 90x140x16mm - High Speed For Industry & Automotive

I. Basic Product Information​

16018E belongs to the category of deep groove ball bearings and is a key component widely used in industrial and civil equipment. The "160" in its model represents a specific size series, and "18" corresponds to the inner diameter of the bearing. This bearing can be accurately adapted to numerous devices, meeting the installation and operation requirements under different working conditions. For example, in the transmission systems of some small to medium-sized mechanical equipment, its size specifications can precisely provide stable support for the shafting.​

II. Structural Design​

1. Rolling Elements and Raceways: High-precision steel balls are used as rolling elements. The steel balls undergo a special grinding process, resulting in extremely low surface roughness and minimal roundness error. In the deep groove raceways of the inner and outer rings, the steel balls can roll smoothly, effectively reducing frictional resistance. The design curvature of the raceways is carefully calculated to perfectly match the steel balls. When bearing loads, the contact stress between the steel balls and the raceways can be evenly distributed, greatly improving the bearing capacity and service life of the bearing.​

2. Cage: Equipped with a cage made of J steel plate stamping. This kind of cage has a lightweight structure and good toughness, which can accurately guide the movement trajectory of the steel balls and prevent collision and friction between the steel balls. Under high-speed operation, the cage can stably separate the steel balls, ensuring that each steel ball can run efficiently on its own track, thus ensuring the high-speed stability and low-noise performance of the bearing. For example, in the high-speed rotating parts of motors, this cage can make the bearing run stably, reducing vibration and noise caused by steel ball collision.​

III. Material Selection​

1. Bearing Steel Material: The inner and outer rings as well as the steel balls of the bearing are made of high-quality bearing steel. This kind of bearing steel has the characteristics of high hardness, high strength and good wear resistance. After strict heat treatment process, its hardness can reach HRC 60-65. When bearing large radial and axial loads, it is not easy to deform and wear, and can maintain the accuracy and performance of the bearing stably for a long time. In equipment such as vibrating screens of construction machinery, even in the face of frequent impact and vibration loads, the 16018E bearing can still operate reliably by virtue of its high-quality bearing steel material.​

2. Cage Material: As mentioned earlier, the cage is made of J steel plate stamping. J steel plate has good stamping performance and can be processed into complex and precise shapes to meet the strict requirements of the cage for guiding the movement of steel balls. At the same time, it has certain strength and toughness. During the long-term operation of the bearing, it can bear the impact and centrifugal force of the steel balls, not easy to break or deform, ensuring the stable guiding effect of the cage on the steel balls.​

IV. Performance Advantages​

1. Low Frictional Resistance: Due to the high-precision cooperation between the rolling elements and the raceways and good lubrication performance, the 16018E bearing has extremely low frictional resistance. This enables the equipment to transmit power more efficiently during operation and reduce energy loss. When applied in small-power motors, it can significantly improve the operating efficiency of the motor, reduce energy consumption and achieve the effect of energy saving.​

2. High Rotational Speed Capability: With its precise structural design and high-quality materials, this bearing can adapt to high-speed working environments. At high-speed rotation, the movement of the steel balls and the cage remains stable without jumping or jamming. For example, in the spindle system of machine tools, the 16018E bearing can support the spindle to run at a relatively high speed, thereby improving the processing efficiency and precision of the machine tool.​

3. Good Load-Bearing Capacity: It can not only bear radial loads, but also bear axial loads to a certain extent. When subjected to radial loads, the steel balls are evenly distributed on the raceways, sharing the load together and effectively dispersing the stress. When bearing axial loads, the structural design of the bearing can ensure a reasonable contact mode between the steel balls and the raceways, so that the bearing can still work stably. In equipment such as automobile and tractor gearboxes, the 16018E bearing needs to bear forces from different directions at the same time, and its good load-bearing capacity can ensure the normal operation of the gearbox.​

V. Application Fields​

1. Industrial Machinery: In the transmission systems of various industrial machinery, the 16018E bearing plays an important role. For example, in the gearbox of machine tools, it provides stable support for the gear shaft, ensuring the accuracy and stability of the gear during high-speed operation and power transmission. On the motor shaft of fans, this bearing can adapt to the long-term continuous operation of fans and ensure the efficient operation of fans.​

2. Transportation: It is widely used in the gearboxes of automobiles and tractors to help realize power transmission and speed change between different gears. Its reliable performance can adapt to frequent shifting operations during vehicle driving and vibration and impact under complex road conditions. In the propulsion systems of some small ships, the 16018E bearing is also used to support the transmission shaft to ensure stable power transmission of the ship.​

3. Household Appliances: In the field of household appliances, such as motors of air conditioners, washing machines and other equipment, the 16018E bearing makes the motor run more smoothly and quietly with its low-noise and low-friction characteristics. In air conditioning compressors, it can bear the high pressure and high speed during the operation of the compressor, ensuring the refrigeration or heating effect of the air conditioner.​

4. Instruments and Meters: In some instruments and meters with high precision requirements, the high precision and stability of the 16018E bearing can ensure the accurate operation of the precision components inside the instruments. For example, in the focusing mechanism of optical microscopes, this bearing can make the focusing process smooth, ensuring that the microscope can accurately focus on the target object.​

VI. Installation and Maintenance Points​

1. Installation Points: During installation, it is necessary to ensure the cleanliness of the installation environment to avoid dust, impurities, etc. from entering the bearing. The matching accuracy of the shaft and the bearing seat is crucial. It is recommended to select m6 for the shaft tolerance and J7 for the bearing seat hole tolerance to ensure a good interference fit and prevent the bearing from loosening during operation. During the installation process, professional installation tools such as a press or hot mounting equipment should be used. When using the hot mounting method, the heating temperature should be strictly controlled between 80℃ and 120℃ to avoid the performance degradation of the bearing material due to excessive temperature. After installation, professional tools should be used to detect the radial and axial clearance of the bearing to ensure that they are within the specified range, so as to ensure the normal operation of the bearing.​

2. Lubrication Points: Select appropriate lubricants according to different application scenarios and working conditions. Under general working conditions, NLGI Grade 2 lithium-based grease can be used, which has good lubricating performance and water resistance. When filling grease for the first time, the filling amount should be 1/3-1/2 of the internal space of the bearing. Under high temperature, high speed or heavy load conditions, it is recommended to use synthetic lubricating oil and equip with a complete lubrication system. Regularly check the oil quality and quantity of the lubricating oil, and timely replenish and replace it to ensure sufficient and effective lubrication of the bearing. For example, in equipment used in high-temperature environments such as steel plants, the frequency of checking and replacing lubricating oil should be increased.​

3. Maintenance Points: Establish a regular maintenance and inspection system, and timely detect potential early faults of the bearing through vibration analysis, temperature detection and other means. It is generally recommended to carry out vibration detection once a week and temperature monitoring once a month. If abnormal increase in bearing vibration or excessive temperature is found, stop the machine immediately for inspection, analyze the cause and take corresponding maintenance measures. At the same time, keep the equipment operating environment clean to prevent dust, impurities, etc. from entering the bearing, affecting the normal service life of the bearing. In dusty mining environments, the sealing protection of the equipment should be strengthened to reduce the damage of dust to the bearing.​
