The DBH 8402Pol is a radial shaft seal built to keep oil and grease where they belong and to keep dust and other contaminants out. Its Lx-R configuration pairs a primary sealing lip with a secondary dust lip, which suits equipment that sees moderate dirt exposure. Maintenance teams commonly encounter this size on gearboxes, pumps and motors.

Reading the size off the box is straightforward: shaft 36 mm, housing 50 mm, height 8.00 mm. In the Lx-R designation, the first lip does the sealing work and the second one acts as an excluder, so lubricant stays in and particles stay out. Because DBH is one of the brands we supply, the fastest way to identify the correct replacement is to match the original part number rather than guessing from appearance alone.

Seals in this size range turn up on gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission assemblies. In each case the job is the same: hold the lubricant in the housing and keep dust or water away from the bearing and the shaft. Treat it as a wear item. Once oil starts weeping from the sealing area or the bearing begins to sound different, the seal is worth inspecting.

Before ordering, confirm all three measurements against the actual shaft and housing, and take a close look at the shaft surface. Scoring, scratches or a visible wear track will keep a new lip from seating properly, so a repair sleeve or an offset-lip seal may be the better route. The Lx-R style fits applications with dust exposure; for high pressure or high speed service, check with us first.

When you send the 8402Pol part number, include the dimensions of the old seal and a note on the application. That is usually enough for us to locate an equivalent in the DBH line or in another brand we carry. We can also help you settle on the right lip configuration based on the lubricant in use and how the equipment runs.

To get a quote, message us on WhatsApp with the part number and the quantity you need. If the size or the design is unclear, a photo of the part or caliper readings will let us confirm the replacement for you. Our team replies promptly and can suggest equivalents when the original is not the only option.
