The DBH 9451 radial shaft seal is a lip seal that mounts in the housing and closes against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Due to its dimensions of 42 mm shaft, 70 mm housing and 8 mm height, with Lx design, it is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this brand and quotes it on WhatsApp.

This item is a DBH radial shaft seal, code 9451, with the following dimensions: shaft diameter 42 mm, housing diameter 70 mm and height 8 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The elastomeric lip works on the shaft and the metal case fits into the housing. It is a wear part: over time the lip hardens or becomes marked and starts to lose oil.

Typical applications for a seal of this size are gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It also appears in machine tools, food industry equipment and conveyor systems. In all cases it performs the same function: separate the lubricated side from the environment, prevent leaks and protect bearings and gears from contaminant ingress.

To mount it, check that the shaft is within tolerance and free of burrs or marks on the sealing track. Lubricate the lip before inserting it and use a mounting tube that bears on the outer edge of the case, never on the lip. If the shaft shows wear, you can consider a seal with an offset lip or a repair sleeve. The selection depends on speed, temperature and the fluid to be retained.

If you need a nearby size or an equivalent from another brand, send us the shaft diameter, housing diameter and height, plus a photo or the code of the original seal. With that data we look for the available option in the DBH line or in the other brands we carry. We can also guide you if the Lx design is not suitable for your application and another type of lip or material is better.
