The DBH 6734 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 28 mm shaft diameter, 47 mm housing diameter and 8 mm height, and Mz-R-H design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the right oil seal for your application.

The DBH 6734 is a single-lip radial shaft seal with the following dimensions: shaft diameter (d) of 28 mm, housing diameter (D) of 47 mm and height (h) of 8.00 mm. Its Mz-R-H design indicates the lip configuration and body material, intended to retain lubricant and exclude contaminants on rotating shafts. The flexible lip runs on the shaft and maintains contact even with slight eccentricity or misalignment.

This type of oil seal is found in applications where a shaft rotates inside a housing: gearboxes, centrifugal pumps, electric motors, compressors, mixers and belt or chain drive equipment. It is also used in agricultural machinery, washing equipment and conveying systems. Its function is to prevent oil leaks and the entry of dust, water or particles that accelerate wear on bearings and gears.

To install it, check that the shaft is clean, free of burrs and marks, and that the sealing surface has the appropriate roughness. Lubricate the lip before inserting it and place the oil seal perpendicular to the shaft, without striking it directly. If the housing has a chamfer, use it to seat the oil seal without damaging the lip. Selection depends on shaft speed, operating temperature and the fluid to be retained; if you have doubts, ask us.

If you need an oil seal equivalent to the DBH 6734 or a neighboring size, send us the full part number, the shaft, housing and height dimensions, and a photo of the part. With that data we look for alternatives in other brands or series that perform the same function. We can also guide you if the Mz-R-H design does not suit your equipment and a different lip type or material is better.
