The DBH 5271 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 25 mm shaft diameter, 40 mm housing and 10 mm height make it suitable for compact gearboxes, pumps and electric motors. MR Accesorios Industriales supplies this brand and advises you so you choose the correct seal for your application.
This item is a radial shaft seal from the DBH line, identified with the part number 5271. It corresponds to a shaft seal with the following dimensions: shaft diameter (d) of 25 mm, housing diameter (D) of 40 mm and height (h) of 10 mm. The Lz design indicates a single-lip configuration with spring, intended for applications where axial space is limited and reliable sealing against oil or grease leaks is required.
Radial shaft seals such as the DBH 5271 are used in equipment where a shaft rotates inside a fixed housing: gearboxes, centrifugal pumps, electric motors, compressors, mixers and belt or chain drives. Their function is twofold: prevent lubricant from escaping and block the entry of dust, water or particles that accelerate wear of bearings and gears. In industrial plants, they are commonly found in process lines, pumping equipment and motion machinery.
To mount an oil seal, verify that the shaft has no burrs or deep marks, lubricate the lip before inserting it and seat it perpendicular to the shaft. The selection depends on rotation speed, working temperature, type of lubricant and differential pressure. If the original oil seal has a different design, it is advisable to compare the lip profile and the elastomer material, since a dimensional replacement is not always equivalent in service.
If you need a neighboring dimension or an equivalent from another brand, send us the complete part number engraved on the oil seal or the shaft, housing and height dimensions. With that data we can look for an alternative within the same category or suggest an oil seal with similar characteristics. We can also advise you on the type of elastomer and spring according to the fluid and temperature of your equipment.
