The DBH 5512 radial shaft seal is a lip seal designed for rotating shafts of 25 mm diameter, with a 47 mm housing and 8 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in pumps, electric motors, gearboxes and power transmission equipment operating in factories, plants and agricultural machinery. MR Accesorios Industriales supplies it as part of its seals and oil seals line.

This item is a seal of Mx design, with a 25 mm shaft, 47 mm housing and 8.00 mm height. The Mx design corresponds to a single lip seal with spring, intended for rotating shafts with internal lubrication. The 5512 nomenclature identifies the dimensional combination within the DBH line. The sealing lip works on the shaft and the outer casing is press-fitted into the bore, providing static and dynamic sealing of the assembly.

Typical applications for a seal of these dimensions include centrifugal pumps, electric motors, gearboxes, compressors, mixers and belt or chain transmission equipment. It is also used in agricultural machinery, such as seeders and harvesters, and in road equipment. In all cases, its function is to protect bearings and prevent oil or grease leaks that contaminate the work environment and cause lubricant loss.

For correct installation, check that the shaft has no burrs or wear and that the surface where the lip seats is clean and lubricated. The seal is inserted with a suitable installation tube, applying uniform pressure on the casing, never on the lip. It is important that the spring remains on the lubricant side. If the shaft has a deep groove, consider replacing the shaft or using a seal with an offset lip.
