Extending the service life of needle roller bearings has always been a topic of great concern. Through long-term research, it has been found that the extension of the service life of needle roller bearings is not only a measure, but also a combination of various aspects, including preservation, cleaning, transportation, use, loading and unloading, etc.
In order to prolong the service life of needle roller bearings, first of all, it can not be exposed to the air, must be stored in a clean, dry and suitable temperature warehouse, but also to avoid putting together with acid, alkali and chemical corrosive substances. At the same time, in its handling process, it is necessary to avoid deformation and damage caused by bumping and falling.
In addition to double-sided sealed bearings with caps, the other bearings are added rust-proof oil when they leave the factory, needle roller bearings are no exception. So it must be cleaned before use, the correct way is to immerse it in gasoline mixed with 8-10% mineral oil, wash off the anti-rust agent on the bearing surface, after cleaning, the bearing can no longer rotate.
Installation quality is also a factor affecting the service life of needle roller bearings. The axles or holes matched with needle roller bearings should be smooth and burr-free. It is easy to install needle roller bearings in place as long as the bearing datum is recognized in accordance with the requirements. After the installation of the bearing, it should rotate flexibly and without stillness.
Another key point is to lubricate needle roller bearings properly, select appropriate lubrication system and high quality lubricants. And regular maintenance can avoid needle roller bearing damage caused by lubrication problems.
In order to prolong the service life of needle roller bearings, it is necessary to improve the performance of needle roller bearings, so reasonable adjustment is very important. When assembling or installing, if the internal clearance of the bearing is too large or too small, or in some cases, the preloading load is too high, which may lead to early damage and shorten the life of the bearing.
