Solve The Noise Generated By SKF Bearings

    It is a part of SKF bearing, and its damage state usually includes deformation, breakage, abrasion, end face deformation, recessed surface/guide surface wear, etc. In order to avoid cage damage, the installation method, load, rotation and temperature conditions should be carefully checked, vibration should also be reduced, and the lubricant and lubrication method should be changed. The inner ring and outer ring of the bearing are a bit inclined. Caused by disassembly of the bearing. It is also a state of SKF bearing damage and has a certain impact on SKF bearings. In order to avoid the existence of this kind of damage state, proper work must be used when installing or disassembling the bearing. To prevent impact load, a punching machine can be used.


    Bearings are generally composed of inner ring, outer ring, rolling elements and cage. The inner ring is mounted on the journal, which is called the shaft ring in the thrust bearing, and the fit is tight; the outer ring is mounted in the SKF bearing hole of the machine base or part, and the fit is usually loose. There are raceways on the inner and outer rings. When the inner and outer rings rotate relatively, the rolling elements will roll along the raceways. The role of the cage is to evenly separate the rolling elements. In order to meet certain requirements, some SKF bearings can have no inner ring or no outer ring, or with dustproof and sealing rings.


    The SKF bearing body will be printed with brand words, labels, etc. The fonts are very small, but most of the products produced by the factory use steel stamping technology, and they are pressed before heat treatment. Therefore, although the fonts are small, they are deeply concave and very clear. The fonts of counterfeit products are not only blurred. Due to the rough printing technology, the fonts float on the surface, and some of them can even be easily erased by hand.


    Whether there is noise in the bearing body of SKF bearing, hold the inner sleeve of SKF bearing with your left hand, and turn the outer sleeve with your right hand to make it rotate, and listen to whether there is any noise. Due to the backward production conditions of most counterfeit products and the completely hand-made workshop operation, it is inevitable that impurities such as sand will be mixed in the bearing body during the production process, so noise will be generated when rotating. This is the biggest difference from a genuine brand that strictly enforces production standards and operates with machines.


    Whether there are turbid oil stains on the surface of SKF bearings, this should be paid special attention to when purchasing SKF bearings. Since the current domestic anti-rust technology is not very popular, it is easy to leave thick oil stains when anti-rust treatment on the bearing body, which is sticky and sticky on the hand, while it is almost invisible on the original foreign SKF bearings. When it comes to the traces of anti-rust oil, a very careful expert said that SKF bearings smelled a kind of smell, it must be the anti-rust oil, but you can't see it.


    SKF bearing seals are more effective than dust caps and are restricted by flexible rotation and lower speed rotation. When selecting the appropriate seal, the designer must consider the performance of the lubricant, the delivery system and the expected working conditions.

    In view of the high load, strong impact force, water and rust intrusion of roller SKF bearings in use, SKF Bearing has developed a new type of sealed, clean and lubricated roller SKF bearing with ultra-high load capacity. It is said that the SKF bearing can increase the load capacity by 34%, has higher reliability, and can work for a long time under severe lubrication conditions. Its improved sealed SKF bearing performance incorporates optimized mechanical principle design, new materials and patented seal technology, and is easy to operate and install.


    In ordinary sealed roll SKF bearings, the main seal and the width limit the length of the roller, which limits the load capacity of the SKF bearing. Therefore, in the new SKF bearing design for rolls, they included the cage ribs in the gaps of the seals to make the rollers longer, so that the diameter of the cage increases and the rollers are lengthened, while the length of the cage does not increase. 34% of the basic rated load capacity is equivalent to extending the life of SKF bearings by 27 times. The high-quality "T-F" SKF bearing steel selected for this SKF bearing is also the key to improving the performance of SKF bearings, because impurities and uneven lubrication in the material are the main reasons for premature failure of SKF bearings.


    Experience has shown that under contaminated working conditions, it is easy to enter debris in SKF bearings, and these debris particles will damage the raceway and cause stress concentration. In addition, if the lubrication is not uniform, the metal surface is hard to contact, causing small "peeling" damage, and will also cause stress concentration in the contact area. These two results will cause the metal surface of the stress concentration location to crack and ultimately shorten the life of SKF bearings.
