Only 25% of bearing performance depends on the quality of the bearing. Other elements such as installation, lubrication and maintenance have the greatest impact on bearing life in theory.
1. Improper assembly
16% of the early failures of various bearings are caused by improper assembly and incorrect use of assembly tools. Some equipment implores the use of mechanical, hydraulic or heating methods to stop correct and effective installation and removal. Bearing provides a full set of tools and equipment based on various professional engineering service technologies, making these tasks simple, fast and more cost-effective. The use of special tools and technology to suspend professional assembly is another way to achieve the maximum extension of machine operating time.
2. Improper lubrication
Although it is possible to install various "maintenance-free" sealed bearings, 36% of early failure bearings are still caused by incorrect technical application and improper use of grease. Any improperly lubricated bearing will inevitably fail prematurely before its normal service life. Since bearings are usually the most difficult parts of mechanical equipment to be assembled and disassembled, infrequent lubrication will cause problems. In the case that manual maintenance cannot be completed, the bearing can be equipped with a fully automatic lubrication system to achieve the best lubrication effect. Simply use bearing grease according to the request, tools and technology to stop effective lubrication, will help greatly reduce downtime.
3. Pollution
Bearings are precision parts. If the bearings and grease are contaminated, they will not operate effectively. In addition, since the maintenance-free sealed bearings that used to be greased accounted for only a small part of all bearings in use, at least 14% of all bearings that failed prematurely were caused by pollution problems. With excellent bearing manufacturing and design capabilities, it can provide sealing solutions for various harsh working environments.
4. Tiredness
Assuming that the machine is overloaded, used or maintained improperly, the bearings will be affected, and 34% of the bearings that cause premature failure are caused by fatigue. Because the bearing will issue an "early warning" when the bearing is improperly maintained or the stress is too high, the bearing condition monitoring equipment can be used to suspend the detection and analysis, so sudden or unplanned failures can be avoided.
The main task of bearing service life analysis is to find out the main elements of bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures to extend the decommissioning period of the bearing and avoid sudden occurrence of bearing Early failure of sex.
(1) Keep the bearing and its working environment clean.
Even small dust invisible to the eyes can have a bad effect on the bearing. Therefore, it is necessary to keep the surroundings clean to prevent dust from entering the bearing.
(2) Use carefully and carefully.
Severe impact on the bearing during use will cause scars and indentations, which will be the cause of the accident. In severe cases, it may crack or break, so be careful.
(3) Use appropriate operating tools.
Avoid replacing with existing tools, you must use appropriate tools.
(4) Pay attention to the corrosion of the bearing.
When handling bearings, sweat on your hands can become a cause of rust. Be careful to operate with clean hands, it is best to wear gloves as much as possible.
