The DBH 5479 oil seal is a radial shaft seal with a 148 mm shaft diameter, 170 mm housing diameter and 15 mm height, in the Lx design. It is used to retain lubricant and exclude contaminants on rotating shafts, inside gearboxes, pumps, electric motors and power transmission equipment. Its elastomeric lip runs on the shaft and its metal case is press-fitted into the housing. It is a wear part: choosing the right size and lip material defines the service life of the assembly.

This item is a DBH radial shaft seal, identified by the code 5479. Its dimensions are 148 mm shaft, 170 mm housing and 15.00 mm height, in the Lx design. The Lx design corresponds to a single-lip seal with a metal case and an auxiliary dust lip, suitable for rotating shafts lubricated with oil or grease. The 148 x 170 x 15.00 nomenclature follows the usual reading order: shaft diameter, housing outside diameter and overall width. Always confirm these three dimensions against the housing before installation.

Seals of this size are found in equipment with large-diameter shafts: speed reducers, centrifugal pumps, mills, mixers, medium and high-power electric motors, and belt or chain drives. They are also used in continuous-process machinery, where the seal prevents oil leaks and keeps dust or water out of the bearing. At these points, seal failure shows up as lubricant loss, bearing contamination and, over time, premature wear of the shaft or housing.

When selecting a radial shaft seal, take into account the shaft surface speed, the operating temperature, the type of lubricant and the differential pressure. The Lx design with an auxiliary lip is suitable where there is dust or splashing. Check that the housing is clean, free of burrs and has the correct diameter; the seal is press-fitted with a suitable tool, never by striking the lip. Lubricate the lip before inserting the shaft and avoid installing it on a worn or scored surface.
