          Materials for Sealing Ring of Slewing Ring Bearin

          Materials for sealing ring of the slewing ring bearing usually is butadiene-acrylonitrile rubber SN7453, structure is often sealing in lip type. In places with the large discrepancy of climate and temperature, can use zeolite base rubber as the material of sealing ring for the slewing ring bearing, its reaction temperature range is much larger than that of butadiene-acrylonitrile rubber, and its highest reaction temperature can reach to 200 ℃. Regarding to sealing structure, there is special structure of sealing ring is shown as double-lip sealing for the wind turbine slewing ring, this sort of structure can avoid radiation and oxidation gases into the roller path, to guarantee quality of the roller path. In some special wind fields under some conditions, materials and structures of sealing ring of the slewing ring should be specially considered.
