The DBH 5913 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. With a 120 mm shaft diameter, 150 mm housing diameter and 12 mm height, and Lz design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you on choosing the correct oil seal for the application.

This item is a DBH 5913 radial shaft seal, identified by its designation 5913. Its dimensions are 120 mm shaft diameter (d), 150 mm housing diameter (D) and 12.00 mm height (h). The Lz design corresponds to a single-lip configuration with a spring, intended to retain lubricant and exclude contaminants on rotating shafts. The elastomeric lip bears against the shaft and the spring keeps the contact pressure constant, while the metal body is press-fitted into the housing.

Typical applications for an oil seal of this size include gearboxes, speed reducers, centrifugal pumps, large electric motors and transmission equipment. It is also found in machine tools, compressors and roller systems where oil leaks and the ingress of dust or water must be prevented. In all cases, the oil seal works on a shaft that turns inside a fixed housing, and its function is to separate two environments with different pressure or with the presence of lubricant.

To install a radial shaft seal, verify that the shaft has the right hardness and surface finish, with no burrs or marks that could damage the lip. The housing must be clean and free of deformation, and it is advisable to lubricate the lip before inserting it. The selection depends on the rotation speed, the working temperature and the type of fluid to be retained. If the shaft shows wear, an oil seal with an auxiliary lip can be evaluated, always confirming with the manufacturer.
