The DBH 5131 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With an 11 mm shaft diameter, 30 mm housing diameter and 10 mm height, and Lx design, it is a compact size widely used in low and medium power equipment. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified with code 5131. Its dimensions are shaft (d) 11 mm, housing (D) 30 mm and height (h) 10.00 mm, with an Lx design. The Lx design corresponds to a seal with a single sealing lip and metal body, intended for rotating shafts where a reliable barrier against oil or grease leaks is needed. The 5131 designation makes it quick to locate in cross-reference tables and seal catalogs.

Typical applications for a seal of this size include small electric motors, reducers, centrifugal pumps, compressors, gearboxes and transmission equipment. It is also used in agricultural machinery, power tools and lubrication systems where radial space is limited. Its function is twofold: retaining lubricant inside the assembly and preventing contaminants from entering that accelerate wear on bearings and bushings.

To install it correctly, check that the shaft has the proper hardness and surface finish, and that the housing is clean and free of burrs. The seal is inserted with the lip facing the lubricant side, using an installation tube or press that presses on the outer diameter, never on the lip. Before installing it, lubricate the lip with the same oil or grease used in the equipment. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
