The DBH 6178 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 30.16 mm shaft diameter, 51.40 mm housing and 11.90 mm height make it suitable for equipment with a defined mounting space. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified with code 6178. Its dimensions are 30.16 mm shaft diameter (d), 51.40 mm housing diameter (D) and 11.90 mm height (h). The Mx design corresponds to a configuration with a sealing lip and metal body, intended for mounting in a cylindrical housing. It is a replacement part for rotating shafts that require lubrication and protection against dust or particles.

Radial shaft seals such as the DBH 6178 are used in gearboxes, pumps, electric motors, drive shafts and industrial equipment in general. Their function is twofold: preventing oil or grease leaks and blocking the entry of dirt, water or chips. In environments with vibration or moderate temperature, a properly selected seal extends the life of bearings and gears. It is commonly found in agricultural machinery, production lines and continuous process equipment.

To install this seal, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. The shaft surface must have a roughness suitable for the lip; a finish that is too rough accelerates wear. Lubricate the lip with the same oil used in the equipment before inserting it and place the seal perpendicular to the shaft, using a tube or press that presses on the outer diameter. Avoid hitting the lip or the spring. If the shaft has a groove or wear, consider a repair sleeve or an alternative size.

If you need a seal equivalent to the DBH 6178 or a nearby size, the most practical approach is to send us the full code, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for a compatible alternative in our line of seals and oil seals. We can also advise you if the Mx design does not suit your mounting and another lip profile or material should be considered. Feel free to ask us about similar options.
