The DBH 5078 is a radial shaft seal built to keep lubricant in and contaminants out of rotating shaft assemblies. It measures 15 mm at the shaft, 30 mm at the housing, and 7.00 mm in height. The seal presses into the housing while its flexible lip rides on the shaft. This makes it a wear item commonly found in pumps, electric motors, gearboxes, and transmission equipment. The Lz design and oil-resistant elastomer suit continuous industrial operation.

This single-lip seal carries the designation 5078. Its nominal dimensions break down as shaft 15 mm, housing 30 mm, and height 7.00 mm. The Lz code identifies both the lip geometry and the body material, configured for oil and grease retention on rotating shafts. DBH is a brand that MR supplies, and the replacement is tracked by its original code to prevent mix-ups during changeouts.

Typical installations include centrifugal pumps, electric motors, reducers, gearboxes, transmission shafts, and process equipment. The seal performs two jobs at once: it holds lubricant within the assembly and blocks dust, water, or particles from entering. Under vibration or moderate temperature, the lip stays in contact with the shaft, which helps protect bearings and bushings. Because an early leak can contaminate the surrounding area or harm internal components, this is a key part in preventive maintenance programs.

When selecting a replacement, measure the shaft and housing diameters with a caliper. The lip needs to sit on a surface free of grooves or heavy wear. If the shaft shows marks, consider a new shaft or a seal with an offset lip. During installation, coat the lip with the same oil or grease used in service, insert it square to the shaft, and tap only on the outer ring. Do not strike the lip, and check that the seal is not crooked. Remove any burrs from the housing before fitting.

To request a quote for code 5078, send the code together with the shaft, housing, and height dimensions. That information allows the same size to be matched in another brand or a seal with a similar design. If space permits, a different height or a double lip can also be reviewed. The more complete the details, the faster the response.

For a quote on the DBH 5078 seal or to ask about an equivalent size, send the code by WhatsApp to MR. If you are unsure about installation or the condition of the shaft, include a photo and the dimensions you measured with a caliper. This confirms the correct part before you order it.
