The DBH 8402Vit radial shaft seal is a lip seal mounted 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 Lx-R design, it is a common replacement part in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand as part of its industrial seals line.

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 drive equipment. It is also used in machine tools, industrial washing equipment and hydraulic systems where oil must 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 would accelerate the wear of bearings and gears.

To install a radial shaft seal correctly, check 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 shaft play, working temperature and the compatibility of the elastomer with the lubricant.

If you need an equivalent, the most practical approach is to send us the part number 8402Vit or the dimensions 36 x 50 x 8 mm by 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 will indicate the direct alternative in the same DBH line or whether another lip configuration should be evaluated. If the housing is worn, we can advise you on mounting options with adhesive or a sleeve.
