For maintenance and purchasing teams, the DBH 1011 radial shaft seal is a lip seal that sits in the housing and runs against the rotating shaft. It keeps lubricant in and keeps dust, water and particles out. The size is shaft 25.40 mm, housing 41.25 mm, width 7.92 mm, with Mz design. MR Industrial Accessories supplies this seal and quotes it by part number.

The DBH 1011 is identified by its 1011 designation and by the three dimensions that matter at the bench: shaft 25.40 mm, housing 41.25 mm, width 7.92 mm. The Mz design refers to the construction variant, with a sealing lip and a metal case. This is a common size in gear reducers, pumps and transmission equipment, where a shaft turns inside a fixed housing and needs a continuous barrier against leaks.

You will find seals of this size in gear reducers, centrifugal pumps, electric motors, rollers and power transmission assemblies. In those positions, the seal protects bearings and gears from outside contamination and stops oil or grease from escaping along the shaft. It also appears in agricultural machinery, conveyors and process equipment with lubricated rotating shafts.

Correct installation starts with clean, burr-free shaft and housing surfaces, and a shaft finish and hardness suited to the lip. Lubricate the lip before pressing the seal in, keep it perpendicular to the shaft, and use a tool that pushes on the outer edge rather than the lip. If the shaft is worn, a wear sleeve is an option. Selection depends on speed, temperature and the fluid being retained.

If you need an equivalent or a different size, send the full code, the designation and the shaft, housing and width dimensions. With that information we can search the radial shaft seal range for a match or a suitable alternative. Details on the fluid, working temperature and mounting type help narrow the options and reduce installation errors.
