The DBH 5175 radial shaft seal is a lip seal that mounts in the housing and closes against the shaft to retain lubricant and block the entry of dust, water or particles. With a 40 mm shaft, 55 mm housing and 8 mm height, and an Lx design, it is a commonly used size in gearboxes, pumps and electric motors. MR Accesorios Industriales carries it as part of its line of seals and oil seals.

The DBH 5175 is a radial shaft seal with an Lx design, a single sealing lip and an outer metal body. Its dimensions are a 40 mm shaft diameter, a 55 mm housing diameter and an 8 mm height. The lip runs on the rotating shaft and the outer diameter is interference-fitted into the housing. The 5175 designation identifies this size within the DBH line, and the code lets you order the same item without ambiguity.

It is used in equipment where a shaft rotates inside a housing with lubricant: gearboxes, centrifugal pumps, electric motors, reducers, mixers and conveyors. It also appears in agricultural and industrial applications where oil leakage and the entry of contaminants must be prevented. When the seal fails, loss of lubricant and the entry of dirt accelerate wear on bearings and gears.

To install it, check that the shaft is within tolerance and free of burrs, and that the housing has no dents or rust. Lubricate the lip before inserting it and apply force on the outer edge, never on the lip. If the shaft shows a wear groove, consider shifting the seal a few millimeters or using a repair sleeve. Shaft speed, temperature and the type of lubricant determine the lip material; confirm that data before choosing.

If you need a neighboring size or an equivalent from another brand, send us code 5175 or the dimensions 40 x 55 x 8 mm and the type of application. We can also look for a seal with a lip made of a different material if the environment involves high temperature or contact with special oils. With that data we review the manufacturer's data sheet and bring you a compatible alternative.
