The company is a manufacturer specializing in the production of tapered roller bearings; The tapered roller bearings produced have a full range of standard sizes and favorable prices. Below we will talk about the causes of bearing scuffing, hoping that it will be useful to readers. The so-called damage to a tapered roller bearing in the form of scuffing (burning) means that the raceways of the rings, the rolling elements and the cage of the tapered roller bearing become intensely heated during rotation until they change color, soften, set and break. The main cause of seizure in tapered roller bearings is poor lubrication of the bearing: perhaps poor quality lubricant was used, or too much or too little lubricant - both incorrect.
Secondly, the cause may be excessive load (too much preload), too high a speed, too little clearance, water or other foreign matter. If neither of the two above cases occurs, then the reason is insufficient accuracy of the shaft and bearing housing, large deformation (deflection) of the shaft. What is the solution? First of all, it is necessary to study the lubricant and lubrication method, select the correct bearing lubricant and quantity, and adjust the choice of tapered roller bearing. It is necessary to examine the fit, bearing clearance and preload, as well as improve the sealing device and check the accuracy of the shaft and bearing housing. When operating tapered roller bearings, it is recommended that care be taken to ensure that steps such as mounting, lubrication and clearance are carried out as accurately and correctly as possible.
