For rotating shafts, the DBH 5122 oil seal keeps lubricant where it belongs and keeps dust, water and other contaminants out. The Lz version uses a sealing lip plus a spring, so the lip stays in contact with the shaft. Its measurements are shaft 28 mm, housing 47 mm, height 10 mm. You will find it in pumps, motors, gearboxes and many other machines, and MR Industrial Accessories can point you to the right size.

The code on this part is 5122, and it comes from the DBH line of radial shaft seals. Reading the size off the box is straightforward: d 28 mm, D 47 mm, h 10 mm. The Lz designation tells you the seal has both a lip and a spring behind it, which is what holds the lip against the shaft. The elastomer body handles oils and greases, while the metal case keeps the seal rigid when it is pressed into place. Units like this are a routine replacement item wherever lubricant has to stay contained.

Centrifugal pumps, electric motors, gear reducers, compressors and machine tools are the usual homes for this seal. In each case it does two jobs at once: it stops oil from escaping and it blocks contaminants from reaching the bearings. Transmission shafts and process equipment also use it where clean lubricant matters.

Before ordering, confirm that the shaft and housing dimensions match the seal. The shaft needs to sit within the recommended tolerance, otherwise the seal may leak or wear out early. A smooth shaft with no burrs and a fine surface finish is what you want. At installation, coat the lip with the same oil used in the equipment and press the seal in with a proper tool so the lip is not damaged. If the shaft is already worn, look at an auxiliary lip seal or a wear sleeve as an option.
