The DBH 8839 is a radial shaft seal built for rotating equipment. It keeps oil or grease where it belongs and blocks dust, water and other contaminants from reaching the bearings. You will find it in gear reducer cases, pumps, electric motors and similar machinery. Shaft 54 mm, housing 80 mm, height 11.10/16.60 mm, design A 074-Bidi. MR Industrial Accessories supplies this brand and helps you match the seal to your application.

The 8839 comes from DBH and is a standard radial lip seal. Read the size as shaft 54 mm, housing 80 mm, width 11.10/16.60 mm. The A 074-Bidi designation points to a double-lip layout, so the seal works on two fronts: it holds lubricant in and keeps external contamination out. The inner lip rides the shaft; the outer diameter presses into the housing bore. This makes it a common replacement item in industrial maintenance.

Where does it go? Gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission components are typical homes for this seal. In each case the job is the same: contain the lubricant and shield bearings and bushings from grit and moisture. Production lines, food processing plants, chemical operations and road equipment all use seals of this type. Check that the lip material suits your lubricant and operating temperature before you install.

Installation notes: inspect the shaft for burrs or grooves that could cut the lip. Coat the seal with the same oil or grease used in the application. Clean the housing bore and remove any old sealant. The 11.10/16.60 mm height reflects a profile with a lip section and a body, so set it to the correct depth in the housing. If the shaft is worn, a repair sleeve or a different size may be the better route.

To get a quote for seal 8839, send the part number or your shaft and housing dimensions on WhatsApp. A photo of the part and the housing also helps us identify the series. We can suggest alternatives with the same A 074-Bidi design or a similar one. The more you tell us — diameters, height, lubricant type, temperature — the more precise our proposal will be.
