The rapping bearing is the key component connecting the rapping shaft and the rapping hammer. Its core function is to support the vibrating shaft and make it rotate continuously and stably under extremely bad working conditions, so as to drive the vibrating hammer to knock the electrode periodically and complete the ash cleaning action.
Product Description
Bearing seat: usually made of cast iron（HT250）or cast steel（ZG230-450）, it provides structural strength and installation foundation.
Bearing bush: the core of bearing bush in direct contact with the vibrating shaft and bearing wear.
The rapping bearing is a seemingly simple yet crucial component in the dust cleaning system of electrostatic precipitators. Its split-type structure and self-lubricating design perfectly address the challenges of rotational support under extreme operating conditions such as high temperature, heavy dust, low speed, and heavy loads. Its stable operation ensures the reliable year-round performance of the rapping cleaning system, making it one of the unsung heroes behind the electrostatic precipitator's ability to achieve over 99.9% dust removal efficiency. When selecting or replacing rapping bearings, the material, precision, and appropriate fit clearance are essential core factors to consider.
