When a gearbox, pump or motor starts weeping oil around the shaft, the DBH 8402Vit radial shaft seal is the kind of replacement part a maintenance team reaches for. It fits a 36 mm shaft, a 50 mm housing bore and an 8.00 mm height, and it carries the Lx-R lip configuration. MR Industrial Accessories supplies it within its industrial seals range for plants and repair shops in the United States and Latin America.

The 8402Vit belongs to the DBH line of radial shaft seals. Read the size as shaft 36 mm, housing 50 mm, height 8.00 mm. Lx-R tells you what is inside: one sealing lip, backed by a spring, built for rotating shafts that run with oil or grease present. The elastomeric lip rides against the shaft while the metal outer case holds the seal tight in the bore. Like any wear part, it gets replaced once lubricant starts escaping or grit starts getting in.

Sizes in this range turn up in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain drive assemblies. Machine tools, industrial washing equipment and hydraulic circuits use them too, wherever oil has to stay separated from the surroundings. The job never changes: hold the lubricant in, keep contaminants out, and protect bearings and gears from the wear that follows when either one fails.

Installation decides how long the seal lasts. Inspect the shaft first for burrs, scratches or a worn contact band, since a rough surface will destroy the lip quickly. Coat the lip with lubricant before pressing it in, and drive it with a tube that bears on the case rather than the elastomer. The 8.00 mm height normally sits flush or slightly recessed, depending on how the equipment is built. When a seal has already failed, check shaft play, operating temperature and whether the elastomer suits the lubricant in use.

Looking for an equivalent? Send the number 8402Vit or the dimensions 36 x 50 x 8 mm by WhatsApp. A photo of the old seal, showing the marking on the lip or case, works just as well. With that information we can point to the direct alternative in the same DBH line or tell you whether a different lip configuration deserves consideration. If the housing bore is worn, we can also discuss mounting with adhesive or a sleeve.

MR Industrial Accessories supplies the DBH brand as part of its seals and oil seals catalog. For a repair or a scheduled maintenance job, send the reference 8402Vit by WhatsApp and we will prepare the quote with the technical details you need. If the part number is not at hand, we can help you confirm the correct size.
