The DBH 5750 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering equipment with a rotating shaft. With dimensions of 101.60 mm shaft diameter, 142.87 mm housing and 12.70 mm height, and an Lz design, it is press-fitted into the housing and runs against the shaft. It is a common replacement part in pumps, gearboxes and electric motors, where reliable sealing extends bearing life and reduces downtime.

This DBH 5750 oil seal has a shaft diameter of 101.60 mm, a housing diameter of 142.87 mm and a height of 12.70 mm. The Lz design corresponds to a configuration with sealing lip and spring, intended to retain oil or grease in continuous rotation applications. The 5750 designation identifies the exact size within the DBH line, and it is essential to verify these three values before replacing a seal, since small differences prevent correct installation or cause leaks.

Radial shaft seals like this one are used in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In those assemblies, the seal prevents lubricant from escaping and dust or moisture from entering the bearings. The size 101.60 x 142.87 x 12.70 mm corresponds to large-diameter shafts, common in heavy machinery, mills, conveyor belts and process equipment. If the seal fails, lubricant loss accelerates bearing wear and can cause unplanned downtime.

To correctly select a seal, you must confirm the shaft diameter, housing diameter and height. Rotation speed, working temperature and type of lubricant also play a role. The Lz design is suitable for shafts with rotary motion and moderate eccentricity. During installation, lubricate the lip with the same oil or grease used in the equipment, insert the seal perpendicularly and verify that the spring is on the lubricant side. Avoid hitting the lip and make sure the shaft has no burrs or marks.
