Material
The MR72ZZ bearing is mainly made of high-quality chrome steel (SUJ2). This material has excellent hardness, wear resistance and fatigue strength, which can ensure the bearing has a long service life even under high-speed operation and heavy load conditions.
Characteristics
1. High precision: The bearing is manufactured with advanced processing technology, ensuring high dimensional accuracy and rotational accuracy, which can meet the requirements of precision mechanical equipment.
2. Low noise: The optimized design of the bearing and the high-quality material reduce the friction between the rolling elements and the raceways, thus achieving low noise operation.
3. Good sealing performance: The double metal shields (ZZ) at both ends of the bearing can effectively prevent dust, dirt and other impurities from entering the bearing, and also prevent the leakage of lubricating grease, ensuring the normal operation of the bearing in harsh environments.
4. High speed capability: Due to the excellent material and reasonable structure, the MR72ZZ bearing can adapt to high-speed rotation, making it suitable for equipment that requires high-speed operation.
Applications
1. Micro motors: Such as small DC motors, stepping motors, etc., the MR72ZZ bearing can ensure the stable operation of the motor at high speed.
2. Precision instruments: Like measuring instruments, optical instruments, etc., its high precision and low noise characteristics can meet the strict requirements of these instruments.
3. Office equipment: For example, printers, scanners, copiers, etc., the bearing can reduce the noise of the equipment and improve the working efficiency.
4. Household appliances: Such as electric shavers, hair dryers, small fans, etc., it can ensure the smooth operation of the appliances and extend their service life.
