The DBH 5057 oil seal is a radial shaft seal with a 25 mm shaft diameter, 47 mm housing bore and 10 mm height, in Lx design. It is used to retain lubricant and exclude contaminants on shafts that rotate inside a housing. It is a common wear part in pumps, electric motors, gearboxes and power transmission equipment. At MR Accesorios Industriales we carry it as part of our seals and oil seals line for industrial maintenance.

This item is a DBH radial shaft seal, identified by part number 5057. Its dimensions are 25.00 mm shaft diameter (d), 47.00 mm housing bore (D) and 10.00 mm height (h). The Lx design corresponds to a single sealing lip with a spring, suitable for rotating shafts. The sealing lip, the outer body and the internal spring work together to keep the lubricant inside the assembly and prevent the ingress of dust or water.

Seals such as the DBH 5057 are used in gearboxes, centrifugal pumps, electric motors, compressors, mixers and power transmission equipment. They also appear in machine tools, conveyors and hydraulic systems where there is a rotating shaft and two environments need to be separated. Their main function is to extend the life of the bearing and the lubricant, reducing leaks and premature wear.

To install a seal, check that the shaft and housing are clean, free of burrs and scratches, and lubricate the lip before inserting it. Pressure must be uniform, without striking the lip or the spring. If the shaft shows wear, it is advisable to evaluate a repair sleeve. Selection depends on speed, temperature and the type of lubricant; if in doubt, contact us with the data of your equipment.

If you need a seal equivalent to the 5057, send us the full part number, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for alternatives in other brands or series we carry. We can also advise you if the space allows a seal of greater or lesser height, or if a design with an additional lip is better for environments with more contamination.
