The DBH 8201 radial shaft seal is a lip seal designed to block lubricant leakage and prevent contaminants from entering rotating shafts. With its dimensions of 51 mm shaft diameter, 61 mm housing diameter and 5.50 mm height, it is installed in gearboxes, pumps and medium-sized motors. MR Accesorios Industriales supplies this brand and advises you so you choose the right seal for your application.

This item is a DBH 8201 radial shaft seal, identified by its designation 8201. Its main attributes are: shaft diameter (d) 51 mm, housing diameter (D) 61 mm and height (h) 5.50 mm. The Lz design indicates a single-lip configuration with spring, suitable for retaining oil or grease on rotating shafts. The lip elastomer and the outer metal reinforcement are designed to work under continuous lubrication and moderate temperature conditions.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases, its function is to keep lubricant inside the assembly and block dust, water or particles that could damage the bearings. It is a wear part that should be replaced when leaks or abnormal noises appear around the seal area.

For correct installation, verify that the shaft has the proper hardness and surface finish, and that the housing is clean and free of burrs. The seal must enter perpendicular, without blows that deform the lip. Before installing it, lubricate the lip with the same service oil or grease. If the shaft shows wear, evaluate a design with an auxiliary lip. The final selection depends on speed, temperature and the type of fluid.

If you need an equivalent, the most practical approach is to send us the code 8201 or the current dimensions (shaft diameter, housing and height). With that data we can look for alternatives in other brands or configurations within the same radial shaft seal category. We can also advise you if the mounting space allows a taller seal or a different lip design.
