The DBH 8199 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and stop dust, water or particles from entering. With a 22 mm shaft, 31 mm housing and 7 mm height, and Lz design, it is a commonly used size in pumps, electric motors, gearboxes and power transmission equipment. At MR Accesorios Industriales we carry it as a brand and advise you so you choose the right seal.

This item is a radial shaft seal from the DBH line, identified by the code 8199. Its dimensions are 22 mm shaft diameter (d), 31 mm housing diameter (D) and 7.00 mm height (h). The Lz design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The elastomeric lip bears on the shaft and the outer metal case fits by interference in the housing. It is a wear part: when the lip hardens or gets marked, it starts losing oil and should be replaced.

Typical applications for a 22 x 31 x 7 mm oil seal are small centrifugal pumps, low-power electric motors, gearboxes, compressors, machine tools and belt or chain drive equipment. In all cases it performs the same function: keeping lubricant inside the assembly and preventing contaminants from entering that accelerate wear on bearings and gears. It is also used as a secondary seal on fan and agitator shafts.

To install it properly, check that the shaft diameter and housing diameter match the stated 22 mm and 31 mm, and that the housing width accepts the 7.00 mm height. The shaft must be clean, free of burrs and splines, and lubricated before inserting the seal. Place it perpendicular, with a tube or shim that bears on the case and not on the lip. If the shaft is worn, consider a seal with the lip in a different position.

We can look for an equivalent within the same radial shaft seal category. For that, it helps if you send us the actual shaft diameter, housing diameter and height measured with a caliper, plus the type of application and the fluid to be retained. With that data we review alternatives from the DBH brand and other lines we carry, always confirming against the manufacturer's data sheet before quoting.

At MR Accesorios Industriales we have worked with oil seals, bearings, housings, power transmission, seals, bushings, mounting tools and lubricants since 1945. If you already have code 8199 or the code of the part it replaces, send it by WhatsApp and we will send you the quote. You can also ask us about an equivalent seal.
