The DBH 5818Vit radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With a 12 mm shaft diameter, 22 mm housing diameter and 7 mm height, and Lz design, it is used in gearboxes, pumps, electric motors and transmission equipment to retain lubricant and block the entry of dust or water. MR Accesorios Industriales supplies this official brand and advises you on selection.

This item is a radial shaft seal from the DBH line, identified as 5818Vit. Its dimensions are 12.00 mm shaft diameter (d), 22.00 mm housing diameter (D) and 7.00 mm height (h). The Lz design corresponds to a sealing lip with spring and metal body, intended for rotating lubricated shafts. The lip elastomer works on the shaft raceway and the outer case fits by interference in the housing, so the seal stays firm and centered.

Typical applications for a seal of this size appear in equipment with small-diameter shafts: electric motors, centrifugal pumps, gear reducers, gearboxes, compressors and machine tools. It is also found in agricultural implements and in transmission lines where oil must be contained and dirt kept out. In all cases it performs two functions: retaining lubricant and acting as a barrier against external contaminants.

To install it, check that the shaft has no burrs or wear and that the surface where the lip rests is polished. Lubricate the lip before inserting it and place the seal with a support tube that pushes on the outer diameter, never on the lip. When selecting, take into account the shaft speed, working temperature and the fluid to be retained. If the housing or shaft are damaged, it is advisable to consider a neighboring size or an alternative design.

If you need an equivalent or a nearby size, send us the code 5818Vit along with the shaft and housing dimensions, a photo of the part and the type of fluid. With that data we look for the option available in the DBH line or a compatible alternative. We can also advise you if the original seal has a different height or if the housing accepts a larger-section seal.
