OTH water sealing
The cooling water and ferric oxide pieces that possibly come into the inside of bearing are first blocked by the moving sealing of contact type formed by water seal and roller edge face, which is the first barrier of the water defensive line. The maze loop formed by water seal, aluminum ring and sealing cap is second barrier of the water defensive line. The sealing of contact type formed by water sealing lip and sealing cap functions as the third barrier of the water defensive line. All the barriers are to guarantee the sealing effect, improve the sealing capacity. The overall performance of the sealing structure is excellent. It is convenient to fix and dismantle it. And its service life is long.
