OTH sealing

OTH oil sealing
Under the function of apparent force and the centrifugal force brought by rotating, the oil throwing lip leads the lubricant vented from the gap of drogue and lining to the oil-returning groove composed by the bearing box and the sealing cap. The vented oil flows along the oil-returning hole and oil-returning box of the bearing box. The plane edge is to confirm the relative position of the roller, drogue, and OTH/C sealing. Normally 10 half circle oil grooves are designed at the plane, which may let the oil in the middle of rollers and drogue to pass (is blocked by the stationary sealing formed by the main lip and the roller), and then to take back to the oil groove by the oil throwing lip. The splashing oil mist throwed by the oil throwing lip is blocked by the contact type sealing formed by the oil sealing lip and the sealing cap. The oil sealing lip, the water sealing lip and the sealing cap flange form the last maze barrier which has a protection effect to sealing.
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.
