When a pump, motor or gearbox starts weeping oil around the shaft, the DBH 5070Sil is one of the seals maintenance techs reach for. It is a single-lip radial shaft seal in an Lz design, sized 42 mm shaft by 62 mm housing by 10 mm height. Its job is simple: hold lubricant in and keep dust, water and particles out.

Reading the code helps you order the right part the first time. DBH identifies the seal family, 5070Sil is the catalog reference, and the three numbers that matter on the bench are 42.00 mm for the shaft (d), 62.00 mm for the housing bore (D) and 10.00 mm for the height (h). The Lz designation tells you the sealing lip is spring-loaded, which is what you want on a rotating, lubricated shaft.

You will find this seal in centrifugal pumps, electric motors, reducers, gearboxes and other power transmission equipment. In every one of those spots it does the same two jobs: it stops oil or grease from escaping and it blocks contaminants from reaching the bearings and bushings behind it. Keeping it in good shape is one of the cheapest ways to avoid unplanned downtime.

Installation is where most premature failures start. Wipe the shaft and housing until they are clean and free of burrs or score marks, then coat the lip with the same oil or grease the equipment runs on. Press it in evenly against the outer face, never against the lip. Line up shaft and housing carefully. If the shaft itself is worn, an oil seal with an extra lip is worth considering.
