Closed filings-removing floating ring oil seal

Disclosed is a closed swarf-removing floating ring oil seal which relates to a bearing lubricating oil seal technique. In the structure of the utility model, a columnar magnet is inlaid on a floating ring which is sleeved on a shaft and forms slit seal or labyrinth seal with the shaft, or an annular magnet is sleeved in connection on the outer circle of the floating ring; the floating ring and the magnet are adsorbed on static seal rings at both ends of the oil seal to form static seal; the magnetic force of line of the magnet is closed by the static seal rings at both ends to avoid magnetic abrasion, and the adsorbing area of the magnet end face is enlarged so that the iron particulates in lubricating oil can be effectively removed; the floating ring can complement the float of the shaft, the clearance between the floating ring and the shaft can be smaller than the general fixed labyrinth oil seal and no abrasion is produced between the floating ring and the shaft. The utility model is characterized by compact structure, simple structure and long service life.
