The DBH 8216 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles. With dimensions of 42 mm shaft diameter, 53 mm housing diameter and 8 mm height, it is press-fitted into the housing and works on the shaft with a flexible lip. It is a wear part that should be replaced at the slightest sign of leakage.

This item is a radial shaft seal from the DBH brand, identified with part number 8216. Its dimensions are 42.00 mm shaft diameter, 53.00 mm housing diameter and 8.00 mm height. The Mx design corresponds to a seal with a single sealing lip, without an additional dust lip. The 8216 nomenclature follows the manufacturer's designation and should not be confused with the series. It is a standard component within the DBH seals line that MR Accesorios Industriales carries.

Radial shaft seals such as the DBH 8216 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their mission is to confine the oil or grease inside the mechanism and block the entry of contaminants. They are common in applications where the shaft rotates continuously and there is a slight pressure difference between the inside and the outside. They also appear in machine tools, conveyors and food industry equipment, provided the lip material is compatible with the fluid.

To mount a seal, check that the shaft diameter and housing match the indicated dimensions. The shaft must be free of burrs, scratches or wear; a rough surface accelerates lip failure. It is advisable to lubricate the lip with the same grease or oil as the equipment before inserting it, and to use a mounting tube that bears on the metal edge, never on the lip. The 8.00 mm height must fit fully into the housing, without deforming the housing. If the shaft shows a groove or a shoulder, evaluate the lip position so that it works on a healthy track.

If you need a nearby size or an equivalent, the most practical approach is to send us the full seal part number, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the original seal has a special design, such as a double lip or dust lip, so that the replacement does not fail due to a construction difference. Do not improvise with approximate dimensions: a wrongly sized seal leaks at the lip or at the housing.
