The DBH 8402Vit radial shaft seal is a lip seal that mounts between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. With dimensions of 36 mm shaft, 50 mm housing and 8 mm height, and an Lx-R design, it is a common replacement part in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this brand as part of its line of industrial seals.

This item is a radial shaft seal from the DBH line, identified by the part number 8402Vit. Its dimensions are 36 mm shaft diameter (d), 50 mm housing diameter (D) and 8.00 mm height (h). The Lx-R design corresponds to a single-lip configuration with a spring, designed for rotating shafts with lubrication. The elastomeric lip runs on the shaft surface and the outer metal case ensures a firm fit in the housing. It is a wear part that is replaced when lubricant leakage or contaminant ingress appears.

Typical applications for a seal of these dimensions include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. It is also used in machine tools, industrial washing equipment and hydraulic systems where oil needs to be separated from the environment. In all cases, the function is the same: keep the lubricant inside the assembly and prevent external agents from entering that accelerate the wear of bearings and gears.

To correctly install a radial shaft seal, verify that the shaft has no burrs, scratches or wear in the contact area; a damaged shaft ruins the lip within a few hours. Lubricate the lip before inserting it and use an installation tube that presses on the case, never on the elastomer. The 8.00 mm height should sit flush or slightly recessed in the housing, depending on the equipment design. If the previous seal failed, also check the shaft play, the operating temperature and the compatibility of the elastomer with the lubricant.

If you need an equivalent or a nearby size, the most practical thing is to send us the part number 8402Vit or the dimensions 36 x 50 x 8 mm via WhatsApp. You can also send a photo of the old seal with the number engraved on the lip or on the case. With that data we verify whether there is a direct alternative in the same DBH line or whether it is better to consider another lip configuration. If the housing is worn, we can advise you on mounting options with adhesive or a sleeve.

MR Accesorios Industriales carries the DBH brand as part of its catalog of seals and oil seals.
