SKF bearing the correct use and common failures - bearing knowledge

There are dozens of rolling cars SKF bearings SKF bearing, large and small almost includes all the common type of SKF bearing, SKF bearing so hit and damage are common. SKF bearing are generally in a body due to the internal, visual inspection, so the inconvenience can only first as general judgment according to the fault phenomena, and then remove the check. Proper use of SKF bearings is to reduce the SKF bearing fault, prolonging the reliable guarantee of SKF bearing life, its content includes the correct installation and reasonable lubrication. The following introduction to the use of SKF bearing requirements. 1. SKF bearing the dismantling of SKF bearing before installation should be clean. When installed, you should use the special tool to auxiliary sell straight uniform pressure into the, don't use hammer percussion, specifically prohibit direct knock on SKF bearing. When the SKF bearing race seat hole cooperate and loose, shall repair or replace the SKF bearing seat hole, do not use on the SKF bearing with surface pitting or pad barely use copper method. SKF bearing removal should be used when appropriate to pull pull the SKF bearing, don't use a chisel, hammer percussion SKF bearing, etc. 2. SKF bearing lubrication SKF bearing two kinds of commonly used lubricants lubricating oil and grease. When the peripheral speed of the shaft is smaller than 4 - 5 m/s, or the car cannot be used lubricating oil, lubricated by grease. Grease lubrication sealing structure of the method is simple, the grease is not easy to drain, little affected by temperature, plus a grease can use a long time. Use grease should pay attention to two questions, one is according to the requirements of the car manual, choose suitable type of grease. Auto water pump SKF bearing, for example, unfavorable choose base grease, due to its poor water resistance. The second is to join in the SKF bearing grease in moderation, generally only 1/2 - filling SKF bearing cavity Too much l / 3 advisable, not only useless, also can increase the running resistance of SKF bearing, warming heat. Special attention should be paid to the wheel bearings SKF bearing, we must promote the 'empty hub lubrication', that is only in the layer of the tu yi on SKF bearing can be just the right amount of grease, otherwise, not only waste and poor heat dissipation, still can make heat grease spillover, may affect the braking performance. Lubricating oil has the advantage of small frictional resistance, and heat dissipation, it is mainly used for high speed and SKF bearing working environment temperature is higher. Brand to choose according to the requirement of the car manual of lubricating oil, and car maintenance cycle change in time, released after the old oil is to add new oil after cleaning of institutions, oil should be added to the line, or refueling and flush ( Depending on the auto specific structure, requirements) , and not more.
