For rotating shafts that need to keep lubricant in and contaminants out, the DBH 5750 radial shaft seal provides a reliable solution. It 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 features a sealing lip with a spring. This seal is press-fitted into the housing and runs against the shaft. It is commonly used in pumps, gearboxes and electric motors, where proper sealing helps extend bearing life and reduce downtime.

The DBH 5750 belongs to the DBH line of radial shaft seals. Its part number, 5750, corresponds to the specific size within that line. The Lz design indicates a lip seal with a spring, intended for retaining oil or grease in continuous rotation applications. Before replacing a seal, always confirm the three critical dimensions: shaft 101.60 mm, housing 142.87 mm, and height 12.70 mm. Small deviations can prevent correct installation or cause leaks.

These seals are found in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In such assemblies, they prevent lubricant from escaping and block dust or moisture from entering the bearing area. The size 101.60 x 142.87 x 12.70 mm fits large-diameter shafts often seen in heavy machinery, mills, conveyor belts and process equipment. A failed seal can lead to lubricant loss, accelerated bearing wear and unplanned downtime.

When selecting a seal, verify shaft diameter, housing diameter and height. Also consider rotation speed, operating temperature and the type of lubricant. The Lz design works well for rotating shafts with moderate eccentricity. During installation, lubricate the lip with the same oil or grease used in the equipment. Press the seal in perpendicularly and ensure the spring faces the lubricant side. Avoid damaging the lip and check that the shaft is free of burrs or marks.

If you need an equivalent size or a variant close to the 5750, send us the full part number and, if possible, a photo of the part and dimensions measured with a caliper. We can search for alternatives within the DBH line or from other brands we supply, always matching the critical dimensions. We can also advise if housing or shaft wear suggests considering a taller seal or a special design.
