The DBH 9169/85 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and water in rotating equipment. It mounts on a 25 mm shaft and in a 40 mm housing, with a total height of 8.20 mm. It is a common wear part in motors, pumps, gearboxes and transmission cases, where it seals the shaft exit and protects the bearings. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal.

This item is a seal of A 016 design, with the following dimensions: shaft diameter 25 mm, housing diameter 40 mm and height 8.20 mm. The A 016 design corresponds to a single-lip seal with spring, suitable for rotating shafts with lubrication. The 9169/85 nomenclature identifies the geometry and the lip material, which is usually nitrile rubber (NBR) for service with mineral oils and greases. Always verify that all three dimensions match the housing and shaft of your equipment before replacing.

Typical applications include electric motors, centrifugal pumps, gearboxes, compressors, machine tools and power transmission equipment. In all these cases, the seal keeps the lubricant inside the assembly and prevents abrasive particles from entering that accelerate wear on bearings and gears. It is also used in industrial washing machines, mixers and conveyors, where dust or water is present. It is an inexpensive part whose periodic replacement extends the service life of the equipment.

To install a seal, work with a clean shaft free of burrs, lubricate the lip with the same grease or oil used in the equipment and press perpendicularly until it seats at the bottom of the housing. Do not strike the lip or deform the spring. When selecting, in addition to the dimensions, take into account the shaft speed, working temperature and type of fluid. If the original seal has a special design, such as double lip or dust guard, it is best to respect it so as not to lose sealing.
