The DBH 9030 oil seal is a radial seal with an 8 mm shaft diameter, 20 mm housing bore and 7 mm height, in the Lx design. It is used to retain lubricant and block the entry of dust or water on rotating shafts. It is a small but critical part: if it fails, it contaminates the lubricant and accelerates wear on bearings and bushings. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

This item is a DBH 9030 radial shaft seal, identified by its designation 9030. Its dimensions are 8 mm shaft diameter (d), 20 mm housing bore diameter (D) and 7.00 mm height (h). The Lx design corresponds to a single sealing lip with a spring, suitable for rotating shafts with lubrication. The DBH brand is an official brand that MR carries, so the product arrives with its factory identification and traceability.

It is used in equipment where an 8 mm shaft rotating inside a 20 mm housing bore must be sealed. It appears in small electric motors, pumps, reducers, fans, machine tools and transmission equipment. Also in applications where the environment contains dust, chips or moisture and the lubricant inside needs to be protected. It is common in industrial equipment maintenance and in the repair of agricultural or process machinery.

To install it, check that the shaft has the right dimensions and surface finish, and that the housing is clean and free of burrs. The seal is installed with the lip facing the lubricant side and with the front face square. It is advisable to lubricate the lip before inserting it and to use a tube or socket that rests on the metal edge, never on the lip. If the shaft shows wear, consider a nearby size or a seal with an offset lip.

If you need an equivalent or a close size, send us the part number 9030 or the shaft, housing bore and height dimensions. With that data we search the DBH line and other brands we carry. We can also advise you if the Lx design is not the most suitable for your application, for example if there is pressure or high speeds. The idea is that you do not buy blindly: first we confirm the part and then we quote.
