The DBH 5249 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and stop dust, water or particles from entering. With 17 mm shaft, 35 mm housing and 8 mm height, it is a common size in pumps, electric motors and low to medium demand gearboxes. MR Accesorios Industriales carries this brand and advises you to choose the correct seal.

This item is a DBH 5249 radial shaft seal, identified by its designation 5249. According to the product page data, it works on a shaft of 17 mm diameter, fits a housing of 35 mm and has 8.00 mm height. The indicated design is Lz, which corresponds to a single sealing lip with spring. It is a standard replacement part, not a special development: it is ordered by code and press-fitted into the housing.

Seals of this size appear in equipment where there is a rotating shaft and two environments must be separated. They are found in small centrifugal pumps, electric motors, gearboxes, compressors, machine tools and transmission equipment. They are also used in agricultural implements and process lines where oil or grease leaks must be avoided. If the equipment works with a lot of dust or water, it is advisable to verify that the lip design is suitable for that environment.

To install a seal, check three things before tapping: that the shaft has no burrs or wear in the contact area, that the housing is clean and free of marks, and that the lip is lubricated. The seal is inserted perpendicularly, with a tube or driver that bears on the outer ring, never on the lip. If the shaft has a groove or shoulder, protect the lip with a sleeve. Once installed, check that it turns freely and is not crooked.

If you need the same seal but in another size, or an equivalent from another brand, send us the code 5249 and the shaft, housing and height dimensions. With that data we search the DBH line or the alternatives we carry. We also tell you whether the Lz design is the one for your application or if another type of lip is better. The more complete the equipment information, the faster the response.
