The DBH 1240Vit radial shaft seal is a lip seal that mounts on the 55 mm shaft and seals against a 72 mm housing. Its stepped height of 8.00/13.30 mm and the A 400 design make it suitable for housings with a deep bore, where the lip must sit properly on the shaft. It is used in rotating equipment to contain lubricant and stop the entry of dust, water or particles. MR Accesorios Industriales carries it as an official brand.

This item is a radial shaft seal from the DBH line, identified as 1240Vit. Its nominal dimensions are 55 mm shaft, 72 mm housing and 8.00/13.30 mm height. The A 400 design corresponds to a construction with a sealing lip and metal body that fits into the housing under pressure. The double height indicates that the seal has a deeper section, intended for housings with a shoulder or to improve the stability of the lip during rotation.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment with continuous rotation. In all cases it performs the function of retaining the oil or grease inside the assembly and preventing contaminants from entering from the outside. It is a wear part: over time the lip hardens or becomes marked and lubricant loss appears.

To mount it, verify that the 55 mm shaft has no burrs or deep marks on the sealing surface, and that the 72 mm housing is clean and free of deformation. Lubricate the lip with the same grease or oil as the equipment before inserting it, and tap evenly on the outer ring, never on the lip. If the shaft shows wear, evaluate a neighboring size or a seal with an offset lip so as not to repeat the failure.
