The DBH 1203 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 contaminants, such as dust or water, which accelerate wear on bearings and bushings. With dimensions of 58 mm shaft diameter, 70 mm housing diameter and 7.50 mm height, and an A 391 Bidi design, it suits applications requiring sealing in both directions of rotation. It is a common replacement part in industrial equipment operating in demanding environments.

This DBH 1203 oil seal has a shaft diameter of 58 mm, a housing diameter of 70 mm and a height of 7.50 mm. Its A 391 Bidi design indicates that it is prepared to seal in both directions of rotation, with two lips working on the shaft. The typical construction of these seals combines an elastomer resistant to oil and heat with a metal reinforcement that gives it rigidity and ensures a firm fit in the housing. It is a reliable solution for shafts rotating at moderate speeds and exposed to splashes or dust.

The most common applications of this type of seal include gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal protects bearings and gears from the entry of particles and prevents oil or grease leaks. It is also used in agricultural, road and process machinery, where a clean environment is not always guaranteed. Its bidirectional design makes it suitable for shafts that can rotate in both directions or for assemblies where internal pressure can reverse.

To correctly select a seal such as the DBH 1203, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The shaft surface must be clean, free of burrs or deep marks, and lubricated before assembly. The seal must be inserted perpendicular to the shaft, with a press or a tube of suitable diameter that rests on the outer ring, never on the lip. If the housing shows wear, evaluate the use of a seal with a sleeve or a retaining adhesive. Correct alignment and adequate lubrication extend the service life of the seal.
