The DBH 5258 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 15.87 mm shaft diameter, 38.07 mm housing bore and 9.52 mm height, and an Lz design, it is press-fitted into the housing and runs against the shaft. It is a key component in pumps, electric motors, gearboxes and equipment where sealing prevents leaks and premature wear.

This DBH 5258 oil seal has a shaft diameter of 15.87 mm, a housing bore of 38.07 mm and a height of 9.52 mm. The Lz design corresponds to a single lip with spring, intended for rotating shafts with lubrication. The 5258 designation identifies the exact size within the DBH line, and the assembly is manufactured with an elastomer resistant to mineral oils and greases, with a metal case for press fitting.

It is used in equipment where the shaft passage through a cover or housing must be sealed: centrifugal pumps, electric motors, gearboxes, compressors, mixers and transmissions. It also appears in machine tools and continuous process equipment. Its function is twofold: to retain the lubricant inside the assembly and to prevent the entry of dust, water or particles that accelerate the wear of bearings and gears.

To select it, verify that the shaft and housing dimensions match those of the original seal. The Lz design tolerates moderate peripheral speeds and low pressures; if the equipment runs at high speed or pressure, another profile should be evaluated. During installation, lubricate the lip with the same oil used in the equipment, insert the seal perpendicular to the housing and avoid striking the lip. A damaged seat or a scratched shaft causes leaks even if the seal is new.
