The DBH 5091 radial shaft seal is a lip seal that closes off lubricant and blocks the entry of dust, water or particles in equipment with a rotating shaft. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for small misalignments. It is a wear part: when oil loss or dirt ingress appears, it is replaced. MR Accesorios Industriales supplies this brand and advises you so you choose the right size.

This item is a DBH radial shaft seal with designation 5091. Its dimensions are shaft 66.68 mm, housing 112.70 mm and height 11.11 mm, in Lx design. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The shaft dimension defines the diameter where the lip runs; the housing dimension, the seat where it is press-fitted; and the height, the total width of the seal. Check all three values before ordering, because even a minimal difference prevents installation or causes leaks.

It is used in gearboxes, pumps, electric motors, mixers, conveyors and power transmission equipment in general. It also appears in agricultural machinery, process lines and plant equipment where shafts rotate inside an oil-filled housing. In all those cases it performs the same function: retain the lubricant on the inner side and prevent contaminants from the environment from entering. If the equipment works with a lot of dust, pressurized water or high temperature, it is advisable to check the condition of the seal more frequently.

To install it, clean the housing and the shaft, check that there are no burrs or marks that could damage the lip, and lubricate the seal before inserting it. The seal must enter perpendicular, without direct blows to the lip; use a tube or driver that presses on the metal edge. When selecting a replacement, respect all three dimensions and the design: a different lip may not seal the same way. If the shaft is worn in the contact area, consider a wear sleeve or an alternative solution before installing the new seal.

If you cannot find the exact size or need an equivalent, send us code 5091 together with the shaft, housing and height dimensions. With that data we look for a compatible alternative within the lines we supply or indicate the closest option. We can also review whether the Lx design is suitable for your application or whether another type of lip is better. The more complete the equipment information, the more accurate the response.
