Oil free sliding bearing manufacturing multi-channel processing process

Oil-free sliding bearings manufacturer of popular multi-channel processing to step through forging, heat processor, turning, grinding and assembly. The reasonableness of the processing technology, advanced, stability will also affect the bearing life. Bearing quality thermal processor and grinding processes, often bearing failure have a more direct relationship. In recent years, research on the bearing surface layer marked transformation, the grinding process is closely related to the bearing surface quality.
Sliding bearings exhibit features advanced fault to a serious failure (usually as axle bearing damage, burns, sand shelf spallation, raceway, wear beads, etc.) Great time not more than a week, the greater the capacity of the device, the faster the speed shorter time intervals. Therefore, in practical bearing fault diagnosis, once found fault with advanced features, it should be decisive to determine the presence of a fault composite bearings, maintenance arrangements as soon as possible.
A period of time after exercise, maintain a certain level of vibration and noise, the spectrum is a single, only for one or two multiplier. Rarely occurs more than three times the frequency spectrum, the composite bearing condition is very stable, into the stable phase. And continue to run into the post-use, bearing vibration and noise begins to increase, sometimes appear abnormal sound, vibration increases but changes more slowly this time, bearing kurtosis values ​​began suddenly reaches a certain value. We believe that at this time sliding bearings that is manifested as initial failure.
