The DBH 5712 radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts, housed in an 81 mm bore. With dimensions of 55.56 mm shaft, 81 mm housing and 11.90 mm height, and an Lz design, it is a common replacement part in gearboxes, pumps and electric motors. MR Accesorios Industriales supplies it as an official brand and advises you so you can choose the correct seal for your equipment.

This item is a radial shaft seal from the DBH brand, identified with part number 5712. Its standard dimensions are: shaft diameter (d) of 55.56 mm, housing diameter (D) of 81 mm and height (h) of 11.90 mm. The Lz design corresponds to a lip configuration with spring, suitable for retaining lubricant and excluding contaminants in rotating applications. It is a precision part that is press-fitted into the housing and seals against the rotating shaft.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In these systems, the seal prevents oil leaks and the entry of dust or water, extending the life of bearings and gears. It is commonly found in industrial machinery, process equipment and heavy-duty vehicles where reliable sealing is required on shafts of approximately 55 mm.

To correctly install a seal such as the 5712, check that the shaft has no burrs or excessive wear in the contact area, and that the housing is clean and free of deformation. Lubricate the lip with compatible grease before installation and place the seal perpendicular to the shaft, using a suitable installation tube. Selection must consider peripheral speed, operating temperature and the type of fluid to be retained; if in doubt, consult our technical team.
