The DBH 9525/85 radial shaft seal is a lip seal that prevents oil or grease leaks and keeps dust out of rotating shafts. Its Lx design and dimensions of 18 mm shaft diameter, 30 mm housing bore and 7.00/8.00 mm height make it suitable for compact equipment. DBH is a brand that MR carries, with technical support to select the right variant for your application.

This item is a radial shaft seal from the DBH line, identified by part number 9525/85. Its dimensions are 18 mm shaft diameter (d), 30 mm housing bore diameter (D) and a height (h) of 7.00/8.00 mm. The Lx design corresponds to a configuration with a sealing lip and metal case, designed to retain lubricant and exclude contaminants on rotating shafts. The 9525/85 designation makes it easy to locate in the catalogue and cross-check against the manufacturer's product page if you need to confirm tolerances or elastomer material.

It is used in gearboxes, pumps, electric motors, transmission shafts and power transmission equipment in general. It also appears in applications with moderate exposure to dust or chips, such as machine tools, conveyors and agro-industrial equipment. Its compact size makes it common in assemblies with limited space, where efficient sealing is required without increasing the housing volume. If your equipment runs at high peripheral speeds or unusual temperatures, it is advisable to review the selection with a specialist.

To install this seal, check that the shaft has the appropriate hardness and surface finish, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and avoid striking it during installation so as not to damage the seal. The 7.00/8.00 mm height means it can be seated in cavities of variable depth within that range. When selecting, consider rotation speed, operating temperature and lubricant type, as these affect the service life of the seal.

If you need an equivalent seal, the most practical approach is to send us part number 9525/85 or the current dimensions (shaft diameter, housing bore and height). With that data we can look for alternatives within the DBH line or other brands we carry, respecting your equipment's tolerances. We can also advise you if the mounting space allows a different height or if the Lx design is not the most suitable for your application.
