Bearing the dustproof sealing ring adopted the edge structure, compared with the existing technology has the following advantages:

Its good seal performance, and its seal high strength. The reasons for its skeleton hooked the edge structure effective elastic sealing ring increased, the maximum compensation scattered the effect of poor threaded size, it can not only by sealing the elastomer elasticity, and roll edge structure effects of elastic and strength action to improve the box cover qualified rate, and machine pressure, can effectively pressure.

 
Seal bearing life greatly depends on the seal performance, now commonly used for sealing ring of bearing ruffled skeleton type, it is often pressed cover by hand, the main drawback is: elastic strength is poorer, assembly and performance is bad, sealed performance is also relatively poor.
