Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures

  • Only 25% of the bearing performance depends on the quality of the bearing. Other factors, such as installation, lubrication and maintenance, actually have a great impact on bearing life.

Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures

  • 16% of the premature failure of various bearings is caused by improper assembly (usually due to excessive force…) and incorrect use of assembly tools. Some equipment requires mechanical, hydraulic or heating methods for correct and effective installation and disassembly.

  • Improper assembly
  • 16% of the premature failure of various bearings is caused by improper assembly (usually due to excessive force…) and incorrect use of assembly tools. Some equipment requires mechanical, hydraulic or heating methods for correct and effective installation and disassembly. 
  • The bearing provides a complete set of tools and equipment based on various professional engineering service technologies, which makes these work simple, fast and more cost-effective. Using special tools and technology for professional assembly is another solution to prolong the running time of the machine to a great extent.
  • Improper lubrication
  • Although various “maintenance free” sealed bearings can be installed, 36% of the premature failure bearings are still caused by incorrect technical application and improper use of grease. Any bearing with improper lubrication will inevitably fail ahead of its normal service life.
  •  Since bearings are usually difficult to load and unload parts in mechanical equipment, problems will occur if they are not lubricated frequently. In the case that manual maintenance cannot be realized, the bearing can formulate a full-automatic lubrication system to achieve the lubrication effect.
  • As long as the bearing grease, tools and technology are used for effective lubrication according to the requirements, it will help to greatly reduce the downtime.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures

contaminated

  • Bearings are precision parts. If bearings and grease are polluted, they will not operate effectively. In addition, since maintenance free sealed bearings that have been filled with grease account for only a small part of all used bearings, at least 14% of all bearings that fail early are caused by pollution. With excellent bearing manufacturing and design capabilities, Koyo can provide sealing solutions for various harsh working environments.
  • fatigue
  • If the machine is overloaded, improperly used or maintained, the bearings will be affected. 34% of the bearings that lead to early failure are caused by fatigue. Because the “advance warning” will be issued when the bearing is improperly maintained or the stress is too large, it can be detected and analyzed by Koyo bearing condition monitoring equipment. Therefore, sudden or unplanned failure can be avoided.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
  • The main task of Koyo bearing service life analysis is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures, prolong the service life of the bearing and avoid sudden early failure of the bearing.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
  • (1) Keep the bearing and its working environment clean.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
  • Even small dust that cannot be seen by the eyes will have a bad impact on Koyo bearings. Therefore, keep the surrounding clean so that the dust will not invade the bearing.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
  • (2) Use with care.
  • Strong impact on the bearing during use will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
  • (3) Use proper operation tools.
  • Avoid replacing with existing tools, and appropriate tools must be used.
  • (4) Pay attention to the corrosion of bearings.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
  • When operating Koyo bearings, sweat on your hands can be the cause of rust. Pay attention to operate with clean hands and wear gloves as much as possible.Causes Affecting the Service Life of Koyo Bearings and Maintenance Measures
