The DBH 5489Sil is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 49.20 mm shaft, a 63.55 mm housing bore and has a 7.14 mm height. The Lx design uses a single lip with a spring, making it suitable for gearboxes, pumps, motors and transmissions where oil or grease must stay contained.

This seal belongs to the DBH line and is identified by part number 5489Sil. The three dimensions to verify are shaft 49.20 mm, housing 63.55 mm and height 7.14 mm. The Lx configuration means a single lip with a garter spring, intended for rotating shafts with lubrication. The elastomeric lip runs against the shaft while the metal outer case is press-fitted into the housing. As a wear part, the lip can harden or score over time and begin to leak.

You will find seals of this size in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. In each case the job is the same: hold the oil or grease inside the assembly and block dust, water or particles from entering. They also appear in agricultural machinery, material handling equipment and production lines where shafts turn in lubricated bearings.

Before installing, inspect the shaft for burrs or wear and make sure the housing is clean and free of dents. Lubricate the lip, then seat the seal with a flat driver to avoid deforming it. When selecting a replacement, respect all three dimensions and the design type. If the shaft has play or the speed is high, consider a configuration with an additional lip or a different material. Temperature and the working fluid also guide the choice of elastomer.
