The DBH 5145Sil is a radial shaft seal sized for a 48 mm shaft, a 72 mm housing bore, and a 10 mm width. Its Lz configuration pairs a primary sealing lip with a secondary outer lip, so lubricant stays where it belongs and outside contamination has a harder time getting in. You'll find this seal in gearboxes, pumps, motors, and other power transmission equipment where keeping oil or grease contained matters for bearing life.

This seal belongs to the DBH line and carries the code 5145Sil. The 48 x 72 x 10 mm dimensions tell you the shaft diameter, housing bore, and overall width. The Lz designation means there are two lips: the main one runs against the shaft to hold lubricant in, while the outer lip acts as a barrier against dust and dirt. The elastomer lip does the dynamic sealing, and the outside diameter presses into the housing for a static seal. It's a wear part that maintenance teams replace routinely.

Seals in this size range show up in gearboxes, centrifugal pumps, electric motors, compressors, and belt- or chain-driven transmission systems. The job is always the same: keep the lubricant inside and keep particles out, which protects the bearings and bushings nearby. You'll also see them in machine tools, conveyors, and process equipment where shafts turn at moderate speeds and oil or grease is present.

When you install one, start by checking the shaft and housing for burrs, scratches, or leftover old seal material. Put a light coat of the same oil or grease used in the equipment on the lip. Press the seal in squarely, using a tube or spacer that contacts only the outer diameter, and never hit the lip directly. If the housing has a chamfer, let it guide the seal into place. After installation, rotate the shaft by hand to make sure nothing rubs.
