The DBH 9902Pol radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. It works on rotating shafts and prevents leaks to the outside, as well as stopping the entry of dust, water or particles. It is press-fitted into the cavity and its lip rests on the shaft with slight interference. It is a wear part: when the lip hardens or the shaft becomes marked, it starts to lose its sealing ability.

This item is a radial shaft seal from the DBH line, identified with the code 9902Pol. Its dimensions are 47.6 mm shaft diameter, 63.7 mm housing diameter and 10.00 mm height, with a design A 340. That combination defines the seat: the lip must rest on a 47.6 mm shaft and the outer body fits into a 63.7 mm cavity. The 10.00 mm height is the space it occupies inside the housing once mounted.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where there is a shaft rotating inside a lubricated housing. It also appears in applications exposed to dust or water, where in addition to retaining the lubricant it must seal toward the outside. It is commonly found in agricultural machinery maintenance, production lines and plant equipment.

To choose correctly, verify that the shaft diameter and the housing diameter match the part to be replaced, and that the height fits into the cavity without being compressed. Check the condition of the shaft: if it has a groove or wear in the lip area, the new seal will not seal. During assembly, lubricate the lip, seat the seal squarely and tap on the outer edge, never on the lip.

To quote the code 9902Pol, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With those three data points we look for the equivalent in the same line or in another brand we carry. If the shaft is worn, we can also look at alternatives with greater height or with an auxiliary lip.
