Types of anti-friction bearings in SKF bearings:
Anti-friction bearings are divided into two main types. They are the Skf bearings and roller bearings. At the same time we also know that, due to the manufacturer and the specific use of double row tapered roller bearings of different, according to which the fundamental structure and evolution of many different kinds.
Lubrication features:
Anti-friction lubricants has the following major features
1. lubricate with 352220e retainer bearing sliding contact to other parts.
2. lubricate washer with not really any contacts between rolling rolls.
3. Lubricate rollers and sliding contact between boot in 352220e bearings.
4. lubricate all the truly rolling contact in bearing.
5. protection of the highly delicate surfaces from corrosion.
6. assist the sealing cap defense foreign material. Greases have magnetic features.
7. provide a thermal (cold) means.
Double row tapered roller bearings are lubricated with oil in the anti-up consists of the following factors: design and load for Skf bearings; oil viscosity, the amount and speed of the bearing.
When oil consumption just at the time of exposure to form a thin film on the surface of friction torque is minimal. But too much oil, friction increases when the oil viscosity is too high. However, in order to maintain a safe lubrication and less friction and loss of attention desire, usually by the majority position. This means that there is more oil is usually heavier oil, will be used in order to reduce the loss due to evaporation or leakage.
However, in general it should be borne in mind that overloading of double row tapered roller bearings and low speed bearings often require heavy oil. Light and fast 352220e bearing need to no lesser degree of oil.
