1. Dimensions

It has a bore diameter of 1.2 mm, an outer diameter of 4 mm, and a width of 2.5 mm. These compact dimensions make it an ideal choice for applications where space is at a premium.

2. Material

• Inner and Outer Rings: Usually made of high - quality chrome steel, such as AISI 52100. Chrome steel offers excellent hardness, wear resistance, and fatigue strength. This ensures a long - lasting bearing life even under demanding operating conditions. For example, in high - speed rotating applications, the chrome - steel rings can withstand the centrifugal forces and frictional heat generated, maintaining the bearing's integrity.

• Balls: The balls within the MR41XZZ bearing are also crafted from chrome steel. Their spherical shape is precisely machined to a high tolerance level. The use of chrome steel for the balls contributes to smooth rotation and efficient load - carrying capacity.

• Shields (ZZ): The "ZZ" in the bearing's name indicates that it is equipped with two metal shields. These shields are typically made of thin - gauge steel. The steel shields serve to protect the bearing's internal components, such as the balls and the raceways, from dust, debris, and other contaminants. They are designed to fit snugly around the bearing, providing an effective barrier without significantly increasing the bearing's overall size or weight.

3. Performance

• Load - Carrying Capacity: Despite its small size, the MR41XZZ bearing can handle both radial and axial loads. The deep - groove design of the bearing allows it to distribute loads evenly across the balls and raceways. It has a certain rated dynamic load capacity, which enables it to support rotating shafts and withstand the forces generated during operation. For instance, in a small - scale motor, it can effectively support the shaft while the motor is running, ensuring smooth rotation.

• Rotation Speed: It has a relatively high - speed capability. The smooth - surface finish of the raceways and balls, along with the appropriate internal clearance, enables the bearing to operate at high rotational speeds. The bearing can reach up to a certain limit of rotational speed, such as [X] RPM (revolutions per minute), under specific lubrication and operating conditions. However, it should be noted that the actual maximum speed may vary depending on factors like the load applied, lubrication quality, and operating temperature.

• Friction and Wear: Thanks to its high - quality materials and precision manufacturing, the MR41XZZ bearing exhibits low friction during operation. Low friction not only reduces energy consumption but also minimizes wear on the bearing components. This results in a longer service life and more stable operation. For example, in a precision instrument where smooth and continuous movement is required, the low - friction characteristic of this bearing ensures accurate operation over an extended period.

4. Sealing

The double - shielded (ZZ) design provides good protection against external contaminants. The shields prevent dust, dirt, and small particles from entering the bearing, which could otherwise cause abrasive wear and premature failure. Although not completely waterproof, the shields can also resist light splashing and moisture in some environments. This sealing feature helps to maintain the integrity of the internal lubricant, ensuring that the bearing operates smoothly without the need for frequent relubrication in relatively clean environments.

5. Applications

• Miniature Motors: In small - sized electric motors used in applications like model airplanes, small household appliances (such as mini - fans or electric toothbrushes), and precision machinery, the MR41XZZ bearing is often employed. It supports the rotating shaft of the motor, allowing for efficient power transmission and smooth operation.

• Instrumentation and Measuring Devices: Due to its high precision and low - friction characteristics, this bearing is suitable for use in instruments such as medical diagnostic equipment, optical measuring devices, and laboratory analyzers. In these applications, the bearing's ability to provide smooth and accurate movement is crucial for the proper functioning of the equipment.

• Aerospace and Defense (Miniature Components): In some miniature components within aerospace and defense systems, where space is limited and high - performance bearings are required, the MR41XZZ bearing can be found. For example, in certain small actuators or sensors used in unmanned aerial vehicles (UAVs) or missile guidance systems, its compact size and reliable performance make it a suitable choice.

• Precision Watches and Clocks: The MR41XZZ bearing can be used in the movement mechanisms of high - precision watches and clocks. Its small size and ability to operate smoothly with minimal friction contribute to the accurate timekeeping of these timepieces.
