The DBH 5520 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 34.93 mm shaft, 52.37 mm housing and 11.11 mm height, it is used in gearboxes, pumps and motors where mounting space is limited. Its Mz design combines a main lip with a secondary exclusion lip, which improves protection in dusty or dirty environments. MR Accesorios Industriales sells this official brand so you can maintain the reliability of your equipment.

This DBH 5520 seal has a designation that reflects its dimensions: 34.93 mm shaft diameter, 52.37 mm housing diameter and 11.11 mm total height. The Mz design incorporates a main sealing lip and a secondary exclusion lip, mounted on a metal body with an outer coating. It is intended for rotating shafts and is press-fitted into the housing. It is important to verify that the dimensions match those of the shaft and the cavity before installation.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors and conveyor rollers. In these machines, the seal prevents oil or grease leaks and blocks the ingress of dust, water or particles. Its double-lip design is suitable for environments with contaminants, such as processing plants, workshops and production lines. It is also used in agricultural and road equipment where exposure to the weather is frequent.

To correctly select a seal, take into account the peripheral shaft speed, the operating temperature and the type of lubricant. The Mz design is appropriate when dirt exclusion is required, but it is essential that the shaft has a smooth surface free of burrs. During installation, lubricate the lip and use an installation tool that does not damage the seal. If the housing has a chamfer, verify that the seal seats fully. These precautions extend the service life of the component.
