  • A Review of Feature Extraction Methods in Vibration

    2017-9-27 · Analyzing the vibration signatures of slew bearings that operate at a very low speed is more complex than that of typical rolling element bearings. Slew bearing signals have low energy. They are also non-stationary, non-linear, chaotic and practically hard to analyze. Due to their low energy, the signal is masked by a higher background noise level.

  • - The Latest in Slewing Ring Bearing Technology

    Sliding slewing ring bearings have excellent vibration-dampening ability. When tested, our PRT slewing ring bearings outperformed roller bearings in atmospheric conditions at 5G’s. The vibration caused the balls in the roller bearing to fly out, while the sliding slewing bearing absorbed the vibration and remained completely intact.
