Oil-free bearing is an important part of contemporary mechanical equipment. The main function of oil-free bearing is to support the mechanical rotating body, reduce the friction coefficient during the movement, and ensure its rotation accuracy. So, how to extend the service life of oil-free bearings? Let's take a look at it together! 1. Fatigue failure of oil-free bearings is a common damage method for bearings, and...
More detailsThin-walled bearing bushes are not allowed to be scratched. The wear-resistant alloy coating on the main bearing of the crankshaft and the connecting rod bearing of the modern vehicle engine is very thin, the dimensional accuracy of the machining is very high, and the surface roughness value is very low. Generally, scratching is not allowed. It can only be selected according to the corresponding size; if there is no ...
More detailsSliding bearings are generally referred to as plane bearings. They have a simple form and a large contact area. If the lubrication is kept well, the anti-wear performance will be very good, and the bearing life will be very long. Sliding bearings have large bearing capacity, high rotation accuracy, and lubricating film with impact resistance, so they are widely used in engineering.The main reasons for the failure of ...
More detailsAccording to the different friction properties in the bearing, the bearing is divided into rolling bearing and sliding bearing. The two types of bearings have their own characteristics in structure and advantages and disadvantages in performance. So, what is the difference between the performance of rolling bearings and sliding bearings? Let's take a look at it together!1. Comparison of structure and movement modeThe...
More detailsComparison of structure and movement modeThe most obvious difference between rolling bearings and plain bearings is the presence or absence of rolling elements. Rolling bearings have rolling elements (balls, cylindrical rollers, tapered rollers, needle rollers), which rotate to support the rotating shaft, so the contact part is a point, and the more rolling elements, the more contact points.Sliding bearings have no r...

Assembly of sliding bearingsSliding bearing is a kind of sliding friction bearing, which is characterized by stable operation, reliability and low noise, and can withstand heavy loads and large impact loads.(1) Assembly of Self-lubricating BearingsIntegral sliding bearings, commonly known as bushings, are also the simplest form of sliding bearings. They are mainly assembled by pressing and hammering. Hot-loading i...
