The DBH 5818Vit radial shaft seal is a lip seal that closes off 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 dust or water. MR Accesorios Industriales sells this 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 a spring and metal case, intended for rotating shafts with lubrication. The lip elastomer runs on the shaft surface and the outer case fits by interference in the housing, so the seal stays firm and centered.

Typical applications for an oil seal of this size appear in equipment with small-diameter shafts: electric motors, centrifugal pumps, gearboxes, gear cases, compressors and machine tools. It is also found in agricultural implements and transmission lines where oil must be contained and dirt kept out. In every case 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 runs is polished. Lubricate the lip before inserting it and seat the oil seal with a support tube that presses 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 is damaged, it is advisable to consider an alternative design.

If you need an equivalent, send us part number 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 available option in the DBH line. We can also advise you if the original oil seal has a different height or if the housing accepts a seal with a larger section.
