The DBH 9840 seal is a labyrinth-type radial seal, designed for 100 mm shafts and 128 mm housings, with a height that varies between 15 and 25 mm depending on the installation. Its main function is to retain lubricant and exclude contaminants in rotating equipment, protecting bearings and internal components. It is a key part in the reliability of industrial machinery, and MR Accesorios Industriales sells it as part of its seals and oil seals line.

This DBH 9840 seal is identified by its designation 9840 and belongs to the radial seal category. Its main dimensions are: shaft diameter 100 mm, housing diameter 128 mm and height 15.00/25.00 mm, which indicates that the lip can adapt to different installation depths. The A 088 design corresponds to a specific labyrinth configuration that improves grease retention and particle exclusion. It is a precision part that must be selected according to operating conditions.

Typical applications for this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. In environments with dust, water or chips, its sealing capacity prevents the entry of contaminants and the loss of lubricant, extending the service life of bearings and shafts. It is common in the food, mining, cement and process industries, where reliability and predictive maintenance are critical.

For correct installation, check that the shaft and housing are clean, free of burrs and scratches, and that the tolerances are suitable for radial seals. Lubricate the lip before inserting it and use an installation tool that applies uniform pressure to avoid damage. Selection must consider rotation speed, operating temperature and the type of fluid to be retained. If you have any doubts, our technical team can advise you.
