Taboo and correct operation in the use of rolling bearings
Rolling bearings are precision products, and there are strict specifications in the process of use, especially in some places that need attention, they must not be done. That is the so-called taboo. Strict requirements in all aspects of rolling bearings include: for example, the end face and non-stressed surface of the bearing cannot be directly hammered, and the bearing cannot be installed by the rolling element transmission force when installing the bearing. The bearing should be installed with a pressure block, sleeve or other professional installation tools Install evenly.
In order to make the installation of the bearing smoother, sometimes lubricating oil can be applied to its surface; if there is a large interference fit, the bearing can be placed in mineral oil and heated to 80~90 °C and installed as soon as possible. In the case of heating installation, the control of oil temperature is very strict, and the specified requirements must not be exceeded, otherwise the bearing will not be installed smoothly.
At the same time, the working clearance after installing the bearing is determined to be smaller than the original clearance before installation, because the bearing also bears the specified load when it rotates. The amount of elastic deformation caused by bearing fit and load cannot be forgotten, and corresponding clearance must be reserved for it.
Select a suitable bearing, the bearing carries a suitable load, in this case, the service life of the bearing will generally be slightly longer than the theoretical life of the bearing. Only if there is a problem in a certain link, various problems occur during the use of the bearing, which affects the service life of the bearing. This is also why some users wonder why the bearings I purchased did not reach the lifespan told by the supplier.
