The DBH 9565 radial shaft seal is a lip seal designed for rotating shafts with a 40 mm diameter, a 55 mm housing and a 7 mm height. Its function is to retain the lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, so the quality of both surfaces defines its service life. It is a common replacement part in pumps, electric motors and gearboxes.

This item is a radial shaft seal from the DBH line, identified by code 9565. Its dimensions are 40 mm shaft diameter, 55 mm housing diameter and 7 mm height. The Lx design corresponds to a seal with a single sealing lip and an outer metal case, intended for press fitting into a cylindrical housing. The 9565 designation groups these standardized dimensions, so any cross-reference inquiry must start from that exact combination.

Typical applications for a seal of this size include centrifugal pumps, low- and medium-power electric motors, speed reducers, transmission shafts and process equipment with rotating shafts. In all cases it performs the dual function of containing the oil or grease and preventing the entry of contaminants. It is also found in machine tools, conveyors and food industry equipment, where cleanliness of the working environment is critical.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the available height. The shaft surface must be ground and free of burrs; excessive roughness wears the lip prematurely. The housing must have a suitable entry chamfer so the lip is not damaged during installation. It is recommended to lubricate the lip before inserting it and to use an installation tube that bears on the metal case, never on the lip.

If you need an equivalent from another brand, the most practical approach is to send us code 9565 along with the shaft, housing and height dimensions you have on the equipment. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also advise you if the original seal has a special geometry, such as a double lip or an additional spring, so that the replacement is the correct one.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals.
