Bearing dust-proof sealing ring by hook rolled edge structure, compared with the existing technique has the following advantages:
Good sealing performance, high sealing strength, reasons for the skeleton hooked edge structure effectively increases the sealing ring is elastic, the maximum size of compensation and dispersion effects, it depends not only on the seal elastomer elasticity, elasticity and strength and volume effect edge structure, improve the qualified rate of the cover, and machine pressure, can effectively.
