The DBH 5078 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 15 mm shaft diameter, 30 mm housing and 7 mm height, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a common wear part in pumps, electric motors, gearboxes and transmission equipment, where it prevents leaks and protects bearings. Its Lz design and oil-resistant elastomer make it suitable for continuous service in industrial conditions.

The DBH 5078 is a single-lip radial shaft seal with designation 5078. Its nominal dimensions are 15 mm shaft diameter (d), 30 mm housing diameter (D) and 7.00 mm height (h). The Lz design indicates the lip configuration and body material, intended for oil and grease retention on rotating shafts. DBH is a brand that MR carries, so the replacement part is identified by its original code to avoid confusion when replacing it.

These seals are used in centrifugal pumps, electric motors, reducers, gearboxes, transmission shafts and process equipment. Their function is twofold: retain the lubricant inside the assembly and block the entry of dust, water or particles. In environments with vibration or moderate temperature, the lip maintains contact on the shaft and extends the life of bearings and bushings. It is a critical part in preventive maintenance, since an early leak can contaminate the surroundings or damage internal components.

To select the correct seal, check the shaft and housing diameters with a caliper. The lip must rest on a surface free of grooves or excessive wear; if the shaft is marked, it is advisable to evaluate a new shaft or a seal with an offset lip. During installation, lubricate the lip with the same service oil or grease, insert it perpendicular to the shaft and tap only on the outer ring. Avoid hitting the lip and verify that it is not crooked. If the housing has burrs, clean it before installing.

To quote code 5078, the most practical approach is to send it along with the shaft, housing and height dimensions. With that data, the same size can be found in another brand or a seal with a similar design. If space allows, a seal with a different height or a double lip can also be evaluated. The more complete the information, the faster the response.
