The DBH 5084Sil is a single-lip radial shaft seal sized 20x40x10 mm. It keeps lubricant in and contaminants out of rotating-shaft assemblies, protecting bearings and bushings from premature wear. This seal is a common replacement item in electric motors, pumps, gearboxes, and transmission equipment, and MR Industrial Accessories supplies it as part of its seals and oil seals line.

The code breaks down into three dimensions: 20 mm shaft diameter, 40 mm housing diameter, and 10 mm height. The Lz designation means a single sealing lip with a spring, built for lubricated rotating shafts. Within the DBH line, 5084Sil identifies both the size and the construction type. The seal presses into the housing, and its lip rides on the shaft to hold oil or grease in place.

You will find this size on low- and medium-power electric motors, centrifugal pumps, gearboxes, compressors, and belt- or chain-driven transmission equipment. It also appears in machine tools, conveyors, and hydraulic systems where the lubricant must stay separated from the environment. Because 20x40x10 is common on fan, agitator, and small roller shafts, it tends to be a regularly consumed spare part in plants and factories.

Before ordering, confirm that the shaft diameter, housing bore, and height match the original part. Check the shaft surface: splines, deep scratches, or wear can prevent the lip from sealing. During installation, lubricate the lip with the same oil or grease used in the equipment, press the seal in perpendicular to the shaft, and avoid striking it. If the shaft is worn, an oil seal with an additional lip may be a better choice.
