Bearings are essential for mechanical operation, but bearings also have their own shortcomings that can not be overcome. Bearing is one of the sound sources that produce mechanical noise. So why are bearings noisy?
Deep groove ball bearings are simple in structure and easy to use. They are the type of bearings with the largest production volume and the widest application range. It is mainly used to bear radial load, but also can bear certain axial load. When the radial clearance of the bearing increases, it has the function of an angular contact bearing and can bear a large axial load.
Rolling bearings often work under high-speed and heavy-load conditions. After long-term use, the rolling elements and raceways will experience wear, ablation, cracking, fatigue spalling, and spots. The inspection of rolling bearings is generally not disassembled. It should be cleaned during inspection, and the quality can be judged through external inspection, idling inspection and internal clearance inspection.
A ball bearing is a low-capacity rolling element that utilizes balls to maintain a unique space between two parts of a rotating system. Ball bearings consist of four main parts. An outer ring, a smaller inner ring, steel balls rolling between the rings, and a cage-like part that keeps the steel balls from banging together during rotation. This structure is so precise and efficient that it has been used for over 500 years.
Bearings with the same appearance under the same working conditions have very different actual life spans. So what effect does the rust prevention of the bearing have on the service life of the bearing?
