The DBH 9849 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles. With dimensions of 22 mm shaft, 40 mm housing and 10 mm height, it is press-fitted into crankcases, pumps, electric motors and gearboxes. It is a wear part that should be replaced at the slightest sign of leakage. MR Accesorios Industriales supplies this brand.

This item is a DBH radial shaft seal, designation 9849, with the following dimensions: shaft diameter 22 mm, housing diameter 40 mm and height 10 mm. The A 158 design corresponds to a single-lipped seal with spring, suitable for lubricated rotating shafts. The DBH nomenclature identifies the seal line that MR supplies as a brand. Before mounting, check that the shaft shows no wear or scoring, and that the housing is clean and free of burrs.

Typical applications for this seal include centrifugal pumps, electric motors, gear reducers, gearboxes, compressors and transmission equipment. In all cases, the seal separates the oil or grease from the external environment, protecting bearings and gears. It is also used in machine tools and process equipment where shafts rotate inside a crankcase. Its compact size makes it common in low- and medium-power equipment.

To correctly select a seal, take into account shaft speed, operating temperature, type of lubricant and differential pressure. The A 158 design with spring is suitable for moderate speeds and low pressures. During mounting, lubricate the lip with the same oil used in the equipment, insert the seal perpendicularly and tap gently on the outer circumference, never on the lip. Verify that the spring is on the lubricant side.

If you need an equivalent seal, the most practical approach is to send us the complete part number, a photo of the part and the measurements taken with a caliper. With that data we can look for alternatives in the same series or in other brands we supply. We can also advise you if the housing has a different diameter or if the shaft is worn and a repair size is advisable. Do not improvise: an incorrect size causes leaks.
