MR62ZZ Micro Ball Bearing Deep Groove For Small Medical Equipment

MR62ZZ Deep Groove Ball Bearing: Micro, Ultra-High Speed, Low Noise & Reliable

I. Product Overview

MR62ZZ deep groove ball bearing is a type of micro precision bearing. With its exquisite design and excellent performance, it plays a key role in small mechanical transmission systems. The bearing has a compact structure, which enables it to operate efficiently in extremely limited spaces, meeting the strict standards of equipment for operation accuracy and stability, and providing a solid guarantee for the stable operation of various small devices. It is widely used in multiple fields, including micro motors, precision instruments and meters, small electronic devices, and small medical equipment, and is an important component to ensure the precise transmission of core parts of small equipment.

II. Structural Design

1. Rolling Elements and Raceways: High-precision steel balls are selected as rolling elements inside the bearing. These steel balls undergo multiple fine grinding processes, with extremely high surface smoothness and extremely precise dimensional accuracy control. They fit closely with the deep groove raceways of the inner and outer rings of the bearing. The radian and depth of the raceways are accurately calculated and designed to ensure uniform contact when the steel balls roll, which can efficiently disperse radial and a certain degree of axial loads. When the equipment is under force during operation, the steel balls roll flexibly in the raceways and smoothly transmit the load through multi-point contact, effectively reducing local wear, maintaining the stability of the bearing operation, and reducing noise.

2. Sealing Structure: The "ZZ" in the model indicates that the bearing is equipped with a double-sided metal dust cover sealing structure. The dust covers are made of high-quality thin metal sheets, formed by precision stamping, and tightly installed on both sides of the bearing to form a tight protective barrier. This structure can effectively block the intrusion of foreign objects such as dust, water vapor, and impurities into the bearing, avoiding contamination and wear of the steel balls and raceways. At the same time, it can protect the pre-filled high-performance grease inside, prevent its loss and deterioration, prolong the lubrication cycle and service life of the bearing, and reduce equipment maintenance costs.

III. Performance Characteristics

1. Excellent High-Speed Performance: MR62ZZ deep groove ball bearing has an extremely low friction coefficient. Thanks to advanced and precise manufacturing processes and the selection of high-quality materials, it can operate stably under high-speed working conditions. In equipment such as micro high-speed motors, it can easily cope with the high-speed rotation of the rotor, achieve efficient power transmission, and generate little heat during operation, greatly reducing the risk of equipment failure caused by overheating.

2. Reliable Bearing Capacity: Although small in size, with reasonable structural design and high-strength materials, the bearing performs excellently in bearing radial loads and can also bear a certain degree of bidirectional axial loads. In small transmission mechanisms, it can not only stably support the rotation of the shaft to cope with radial forces but also effectively resist axial forces generated during equipment operation, ensuring the continuous and stable operation of the equipment.

3. Low Noise and Low Vibration: The precision processing technology ensures the high-precision fit between various parts of the bearing. The rolling trajectory of the steel balls in the raceways is stable and orderly, which significantly reduces vibration and noise. In precision instruments with strict requirements on the operating environment, such as micro measuring instruments, the bearing can ensure quiet operation of the equipment without interfering with measurement accuracy, providing strong support for the accurate work of the equipment.

IV. Application Fields

1. Micro Motor Field: Widely used in various micro motors, such as small fan motors, precision instrument drive motors, and toy motors. As a supporting component of the motor rotor, it can ensure that the rotor remains stable during high-speed rotation, reduce vibration and noise, improve the operating efficiency and reliability of the motor, and extend the service life of the motor.

2. Precision Instrument Industry: In precision equipment such as micro measuring instruments, electron microscopes, and small sensors, MR62ZZ deep groove ball bearing, with its characteristics of high precision and low noise, meets the strict requirements of the equipment for component precision, ensuring the accuracy of instrument measurement data and the stability of operation.

3. Small Electronic Products: Commonly found in the transmission components of small electronic devices, such as the paper feeding mechanism of portable printers and the lens adjustment device of small projectors. Its compact structure and stable performance meet the design requirements of miniaturization and lightweight of equipment, ensuring the normal operation of the equipment.

4. Medical Device Field: In small medical devices, such as micro infusion pumps and portable physiotherapy instruments, the bearing can meet the requirements of the equipment for operation stability and low noise, ensuring the safe and reliable use of medical devices and improving the user experience of patients.

VI. Maintenance Points

1. Lubrication Management: The bearing is pre-filled with an appropriate amount of high-performance grease at the factory, and no frequent addition is required in normal working environments. However, in harsh working conditions such as high temperature, high humidity, or heavy dust, it is necessary to regularly check the state of the grease. If the grease is found to be dry, discolored, or mixed with impurities, the suitable grease should be replaced in time, and the filling amount should be moderate to ensure a good lubrication effect.

2. Regular Inspection: Regularly conduct a visual inspection of the bearing to check whether the dust covers are intact and whether there are any damages, deformations, or looseness. Use professional instruments to monitor the vibration and temperature of the bearing during operation. If the vibration increases abnormally or the temperature exceeds the normal range (usually, the normal working temperature is 10 - 20℃ higher than the ambient temperature), it is necessary to stop the machine immediately for inspection, investigate the cause of the fault, and repair or replace it in time to prevent the fault from expanding.

3. Installation Notes: Ensure a clean environment during installation to avoid foreign objects entering the inside of the bearing. Use appropriate installation tools and operate in accordance with the correct installation method to ensure that the matching accuracy between the bearing and the shaft and bearing seat meets the requirements. Avoid impact damage to the bearing during installation to ensure its normal operation and performance.
