Product Description

Product Description

The MR105 bearing, as a miniature deep groove ball bearing, plays a crucial role in numerous precision equipment fields. Despite its small size, it possesses powerful performance. 
From the structural composition perspective, the MR105 bearing consists of an inner ring, an outer ring, rolling elements, and a cage. The inner ring usually fits tightly with the shaft and rotates synchronously with it; the outer ring is installed in the bearing housing or related mechanical components, providing support. The rolling elements are made of high-strength steel balls, evenly distributed between the inner and outer ring raceways, reducing friction through rolling instead of sliding, significantly lowering the resistance during operation and ensuring smoother rotation, effectively reducing energy loss. The presence of the cage is crucial as it evenly separates the steel balls, preventing collisions and ensuring the smooth operation of the bearing and maintaining good accuracy. 
In terms of the working principle, when the shaft drives the inner ring to rotate, the rolling elements roll between the inner and outer ring raceways, efficiently transmitting the rotational motion and evenly distributing the load they bear. This design enables the MR105 bearing to maintain high accuracy even at high rotational speeds, ensuring that the related components operate according to the predetermined trajectory. However, if the lubrication conditions are poor or the sealing fails, the friction between the rolling elements and the raceways will increase, generating a large amount of heat, which will shorten the bearing's service life and even cause abnormal wear. 
The MR105 bearing has several remarkable performance advantages. Firstly, it has high speed adaptability, thanks to its precise structure and high-quality materials, it can operate stably at high rotational speeds, meeting the requirements of some equipment with strict rotational speed demands. Secondly, it has high rotational accuracy, with precisely machined raceways and precisely matched rolling elements, which control radial and axial runout within extremely small ranges, ensuring the stability and accuracy of equipment operation. Moreover, in a limited space, it can effectively bear a certain load, providing the possibility for the compact design of equipment. 
The application scenarios of the MR105 bearing are very extensive. In electric motors, it can ensure the efficient and stable rotation of the rotor, achieving efficient conversion of electrical energy to mechanical energy; in dental equipment, its high-precision operation characteristics ensure the precise operation of drill heads and other components, providing reliable support for medical work; in the joints of small robots, it helps the robot to move flexibly, achieving precise motion control; in some high-end remote control model cars, aircraft, helicopters, etc., the MR105 bearing, with its outstanding high-speed performance and rotational accuracy, enhances the control performance and flight stability of the models. If the MR105 bearing fails, the related equipment may experience abnormal noise, increased vibration, unstable rotational speed, and other problems, seriously affecting the normal operation of the equipment. Therefore, regular inspection of its lubrication conditions, sealing status, etc., and timely maintenance and care are important measures to ensure the long-term stable operation of the equipment.
