Sealed Four-row Taper Roller Bearing with Good Heat Resistance and High Chemical Stability
Advantages of four row taper roller bearing with seal ringCompared with open type bearing structure without seal ring, four row taper roller bearing with seal ring has many following advantages: They can reach longer service lifeCompared with open type structure without seal ring, consumption of lubricating grease of bearing is obviously decreasedCertain period can be prolonged for interval time for maintenance of bearingThey can use same installation size to replace current open structural bearing without seal ringSeal ring is cast from reinforced thin steel plate framework and fluororubberIts clamping spring can guarantee certain pressure of lip of seal ringWhen work slid speed is less than 35m/s, seal ring has good heat resistance and high chemical stability and work temperature can approximate -20 to 150°C
