The DBH 5031Pol radial shaft seal is a lip seal mounted in the housing that closes against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 28 mm shaft, 40 mm housing and 7 mm height place it in small and medium-sized equipment, where axial space is limited. MR Accesorios Industriales carries it as part of its line of seals and oil seals for maintenance and replacement.

This item is a seal with Lx design, with the dimensions indicated in its designation: 28.00 mm shaft diameter, 40.00 mm housing diameter and 7.00 mm height. The Lx design corresponds to a single-lip seal with a metal body and sealing lip, intended for lubricated rotating shafts. The 5031Pol nomenclature identifies the part within the DBH line and allows it to be ordered without ambiguity when replacing a worn seal.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil or grease must be separated from the environment. It also appears in machine tools, conveyors and washing equipment, where the seal protects the bearings from water and dust. It is a wear part: it is advisable to check it when there is lubricant loss, bearing noise or dirt accumulation around the shaft.

To select it, verify that the shaft diameter, housing diameter and height match the original seal. Check the condition of the shaft surface: a scratched or burred track ruins the new lip within a few hours. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid hitting it with sharp tools. If the housing has burrs, clean them before fitting the part.

If you cannot find part number 5031Pol or need a nearby size, send us the dimensions of the old seal —shaft diameter, housing diameter and height— and a photo of the part. With that data we look for the equivalent in the DBH line or in another brand we carry. We can also advise you if the Lx design is not suitable for your application and a different lip type or material is needed.
