SKF bearings are a kind of central nervous system in dull operation. They work day and night, and keep advancing, like the legendary perpetual motion machine. Perpetual motion machines do not exist at all. A thing always has its life cycle and its own life span. This is a fact that we have to accept, we can only do everything po...

1. The radial load of SKF imported bearings The bearings that mainly bear the radial load are radial bearings. The nominal contact angle of this type of bearing a0=450. Roller bearings with the same gauge rain can withstand greater radial loads than ball bearings. N-type and NU-type cylindrical roller bearings can only bear radi...

NTN bearing pre-tightening force is carried out at room temperature, but in working condition, the drive shaft and bearing pre-tightening force produced by the systems micro-stretching temperature rise will change. Therefore, you should consider this when setting the pre-tightening force. factor. It needs the capacity, speed, an...

1. Vibration of SKF bearings SKF bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, cracks, wear, etc., will be reflected in the bearing vibration measurement, so it can be measured by using a special bearing vibration measurement device (frequency analyzer, etc.) The magnitude of the vibr...

If there are bumps, rust layers, abrasive particles, sand, dust and soil on the assembly surface of the NTN bearing and its mating parts, it is difficult to install the bearing and the assembly position is incorrect; second, these attachments form abrasives, The working surface of the bearing is easy to wear, which affects the a...

Generally speaking, SKF bearings will heat up after starting to run, and after a period of time, they will be at a lower temperature (usually 10 to 40 degrees higher than room temperature). The time to normal depends on the bearing size, form, rotation speed, lubrication method, and changes in the heat release conditions around ...

SKF rolling bearings are one of the indispensable basic components of running machinery. Although the rolling bearing is small in size and low in cost, once the rolling bearing fails, the loss to the running machinery and the entire production equipment is huge. With the rapid development of technology, enterprises have higher a...

SKF bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, cracks, wear, etc. will be reflected in the deep groove ball bearing vibration measurement, so, by using a special bearing vibration measuring device (frequency analyzer, etc.) The size of the vibration can be measured, and the specifi...

Many mechanical failures are related to the FAG rolling bearings in rotation. The quality of the bearings has a great impact on the working state of the machinery. Its defects can cause abnormal vibration and noise in the equipment, and even damage the equipment in severe cases. The correct condition monitoring and diagnosis of ...
