The DBH 5252 radial shaft seal is a lip seal designed to close off the passage of oil, grease or contaminants on rotating shafts. It is mounted in cylindrical housings and works on the shaft with a flexible lip that maintains sealing during rotation. It is a common wear part in gear reducers, pumps, electric motors and transmission equipment, where it prevents leaks and protects bearings from the entry of dust or water. Its 5252 designation corresponds to a standard size of 20 mm shaft, 35 mm housing and 10 mm height.

This item is a radial shaft seal from the DBH line, identified with the code 5252. Its nominal dimensions are 20 mm shaft diameter (d), 35 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip configuration with a spring, suitable for lubricated rotating shafts. DBH is a brand that MR carries, so the product arrives with its original factory designation and dimensions.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases it fulfills the function of retaining lubricant inside the assembly and preventing external particles from entering. It is also used in machine tools, industrial washing equipment and hydraulic systems where the shaft rotates continuously or intermittently.

For correct installation, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal with an installation tool that rests on the outer diameter, never on the lip. Selection depends on rotation speed, working temperature and the type of fluid to be retained; if you have doubts, consult us with your equipment data.

If you need an equivalent or a nearby size, send us the complete part number of the original seal, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for an alternative within the same DBH line or from another brand we carry. We can also advise you if the mounting space allows a different height or a design with an additional lip for greater protection against contaminants.
