With dimensions of 46.43 mm shaft diameter, 69.78 mm housing bore and 12.30 mm height, it is used in gearboxes, pumps, electric motors and industrial equipment where reliable sealing is critical. Its Lx design combines a sealing lip with an auxiliary exclusion lip, offering double protection in demanding environments.

This DBH 5345 oil seal has a shaft diameter of 46.43 mm, a housing bore of 69.78 mm and a height of 12.30 mm. Its Lx design incorporates a main sealing lip and a secondary exclusion lip, which improves grease retention and prevents the ingress of dust or water. The lip elastomer is formulated to resist mineral and synthetic oils, and the internal spring maintains contact pressure on the shaft. It is a key component for extending the service life of bearings and gears.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In these systems, the seal prevents lubricant leaks and the entry of abrasive particles that accelerate wear. It is also used in agricultural machinery, mining equipment and process lines where lubricant cleanliness is essential. Its double-lip design is suitable for environments with dust or splashing.

For correct installation, verify that the shaft has adequate surface hardness and controlled roughness, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and use an installation tool that applies uniform pressure on the outer diameter. Selection must consider rotation speed, operating temperature and the type of fluid to be retained. If the original seal shows premature wear, check the alignment and the condition of the shaft.
