The DBH 1011 radial shaft seal is a lip seal mounted in the housing that seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With 25.40 mm shaft, 41.25 mm housing and 7.92 mm height, and Mz design, it is a commonly used size in gear reducers, pumps and transmission equipment. MR Accesorios Industriales carries it as an official brand and quotes it on WhatsApp.

This item is a DBH 1011 radial shaft seal, identified by its designation 1011 and by the dimensions shown in its data sheet: shaft diameter 25.40 mm, housing diameter 41.25 mm and height 7.92 mm. The Mz design corresponds to the construction variant of this seal, with a sealing lip and metal body. It is a component of the seals and oil seals category, intended for shafts that rotate inside a fixed housing and need a continuous barrier against leaks.

Typical applications for a seal of this size appear in gear reducers, centrifugal pumps, electric motors, rollers and power transmission equipment. In these assemblies, the seal protects the bearings and gears from external contamination and prevents oil or grease from escaping through the shaft passage. It is also used in agricultural machinery, conveyors and process equipment where there are rotating shafts with permanent lubrication.

To install it properly, verify that the shaft and housing are clean, free of burrs or marks, and that the shaft surface has the hardness and finish suitable for the lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tool that presses on the outer edge and not on the lip. If the shaft shows wear, consider a neighboring size or a wear sleeve. Selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a different size, send us the full code, the designation and the shaft, housing and height dimensions. With that data we can look for an alternative within the same radial shaft seal category or a neighboring size that fits your equipment. It also helps if you tell us the fluid, the working temperature and the type of mounting, so we can narrow the search and avoid installation errors.
