The DBH 8885 is a radial shaft seal built to keep lubricant inside a housing and keep dust, water and other particles out. Its dimensions are shaft 30.00 mm, housing 50.00 mm and height 8.00 mm, and it comes in the Lx design. Sizes like this one turn up often in pumps, gearboxes and electric motors. MR Industrial Accessories supplies the DBH brand as part of its seals and oil seals line.

Reading the code is straightforward. The 8885 identifies the item, and the three figures that follow on the product page describe where it fits: d = 30.00 mm for the shaft, D = 50.00 mm for the housing bore and h = 8.00 mm for the height. The Lx design means a single lip with a spring, positioned so the lip faces the lubricant. In service the seal turns with the shaft while its lip rubs against the bore, which is how it holds oil or grease in and keeps contaminants out.

You will find this size on equipment that runs a 30 mm nominal shaft: centrifugal pumps, gearboxes, electric motors, reducers, mixers, and belt or chain drives, as well as machine tools, washing equipment and conveyors. Any assembly that separates a lubricated cavity from the surrounding environment is a candidate. A single-lip Lx seal works well at moderate speeds and low pressures, as long as the shaft surface is in good shape.

Selection comes down to a few operating details: how fast the shaft turns at the lip, the temperature the seal will see, and which lubricant is in use. The lip needs a running surface that is hard enough, has the right roughness and shows no burrs, scratches or wear. Coat the lip with the same oil or grease used in the unit before pressing it in, and make sure the spring is seated. The bore should be clean and free of dents, and the driver you use has to push straight so the lip is not cut or the seal distorted.

Looking for a replacement? Send the code 8885 or the full designation together with the shaft, housing and height measurements. It also helps to name the equipment, the brand of the seal being replaced and a photo of the part. From there we can search for an alternative from DBH, from another brand in our range, or a seal that suits the housing. Depending on what the housing accepts, seals come with or without a spring and in different lip materials.
