The DBH 9303 is a radial shaft seal with a single lip, sized for a 50 mm shaft, a 62 mm housing bore and a 7 mm width. Its Lx configuration combines a sealing lip with a metal outer case, making it suitable for rotating shafts that run with oil or grease. This seal keeps lubricant in place and blocks dust, water and other particles from reaching the bearings. It is a common replacement item in gearboxes, pumps, motors and transmissions.

The code 9303 follows the DBH numbering logic: the first two digits give the shaft diameter and the last two the housing bore, both in millimeters. The Lx design indicates a lip seal with a metal body. When you read the code, you can quickly confirm the dimensions: shaft 50 mm, housing 62 mm, width 7 mm.

Typical installations include gear reducers, centrifugal pumps, electric motors, transmission shafts and machine tools. The seal also appears in agricultural and general industrial equipment where shaft speed is moderate and operating temperature stays within the limits of the standard elastomer. In these positions, it protects bearings from contaminants and prevents lubricant loss.

Before fitting the DBH 9303, clean the shaft and housing bore and remove any burrs or scratches. Apply a thin film of the same oil or grease used in the machine to the lip, then press the seal in evenly until it seats against the housing shoulder. If the shaft shows wear, an auxiliary lip version may be worth considering. Final selection depends on speed, temperature and the fluid being sealed; with those details we can confirm whether the 9303 fits your application.

If you need a cross-reference, send the complete code from the old seal along with the shaft, housing and width measurements and a photo. A drawing or equipment data sheet also helps. From there we can check our seal and oil seal line for a match or point you to the closest option in the series.
