The rolling Koyo bearing selection is a precision component, and its use must be carried out with corresponding caution. No matter how high-performance Koyo bearings are used, if they are not used properly, they will not get the expected high performance.
Keep the Koyo bearing selection and its surroundings clean.Even small dust that cannot be seen by the eyes will bring bad effects to Koyo bearings. Therefore, keep the surrounding clean so that dust will not invade the Koyo bearing.
Use carefully.Strong impact on Koyo bearing in use will produce scars and indentation, which will become the cause of the accident. In serious cases, cracks and fractures will occur, so attention must be paid.
Use proper operation tools.Avoid replacing with existing tools, and appropriate tools must be used.
Pay attention to the corrosion of Koyo bearing selection.When operating Koyo bearings, sweat on your hands will become the cause of rust. Pay attention to operate with clean hands and try to wear gloves.In order to maintain the original performance of Koyo bearings in good condition for as long as possible, it is necessary to maintain and repair them in order to prevent accidents, ensure the reliability of operation, and improve the productivity and economy.
Maintain the operation standard of corresponding mechanical operation conditions, and carry out it regularly. The contents include monitoring the running state, supplementing or changing the lubricant, and settingInspection of phase I disassembly.
