The DBH 8440 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of external contaminants such as dust or water. With dimensions of 30 mm shaft diameter, 52 mm housing and a height of 8.00/10.00 mm, it is used in industrial equipment that requires a reliable barrier. MR Accesorios Industriales supplies this official brand so you can keep your machines running.

This DBH 8440 oil seal has a designation that corresponds to its numeric code. Its main attributes are: shaft diameter (d) of 30 mm, housing diameter (D) of 52 mm and height (h) of 8.00/10.00 mm. The A 135 design corresponds to a specific lip and case configuration, which ensures a precise fit in the cavity. It is a direct replacement part for applications where axial space is limited and efficient sealing is required.

Radial shaft seals such as the DBH 8440 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their ability to withstand moderate speeds and low pressures makes them suitable for environments with oil or grease. In the food, chemical or manufacturing industry, they serve to protect bearings and extend the service life of the assembly. If your equipment has a 30 mm shaft and a 52 mm housing, this seal is the right one.

To install the seal correctly, verify that the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The 8.00/10.00 mm height allows some tolerance in the housing depth. When selecting a replacement, consider the rotation speed, operating temperature and the type of fluid to be retained. The A 135 design is a reference that helps you compare with other options on the market.
