When a rotating shaft needs a dependable barrier between lubricant and the surrounding environment, a radial lip seal such as the DBH 8409 does the job. It fits a 45 mm shaft, seats in a 73.10 mm housing bore and measures 13 mm in height, and it carries the A 113-Bidi designation. MR Industrial Accessories supplies this brand and can help you confirm whether it matches your equipment before you order.

Reading the code: DBH identifies the seal family and 8409 is the item reference. The three figures that matter for fit are shaft 45 mm, housing 73.10 mm and height 13.00 mm. The A 113-Bidi designation describes a double-lip arrangement, meaning a primary sealing lip works alongside a secondary lip that keeps dust and dirt away from the sealing edge. The lip rides on the rotating shaft while the outer diameter holds position in the bore, so the part separates the lubricant inside the machine from whatever is outside it.

You will find seals of this type in gearboxes, pumps, electric motors, rollers and other power transmission assemblies. Performance depends on the conditions of each installation, including shaft speed, operating temperature and pressure at the seal. Agricultural machinery, process equipment and production lines are among the places where this kind of barrier is expected to hold up over long running hours.

Installation calls for a clean bore and a shaft free of burrs, nicks or scoring. Coat the lip with the same oil or grease the equipment uses, then press the seal in evenly by applying force to the outer diameter only. Never drive it in by the lip. If the housing bore shows wear or grooves, a seal with a larger outer diameter or a repair sleeve may be the better route.

If you need a cross-reference, send the original code, the shaft and housing dimensions, and the operating conditions such as speed, temperature and fluid. The team can look at options in other brands or lip configurations while keeping the critical dimensions of your equipment intact. A photo of the part also helps confirm the match.
