The DBH 8770Pol radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its Lx-Bidi design combines a main sealing lip with a secondary exclusion lip, making it suitable for equipment exposed to moderate contamination. It is used in gearboxes, pumps, electric motors and transmissions where the shaft rotates continuously. MR Accesorios Industriales carries this official brand and advises you on choosing the right size.

This item is a seal from the DBH line, identified by the code 8770Pol. Its nominal dimensions are: shaft diameter 140 mm, housing diameter 170 mm and height 15.00 mm. The Lx-Bidi design indicates a lip seal with double action: a main sealing lip and a secondary exclusion lip. This configuration improves performance against dust and splashes, and reduces the risk of contaminant reaching the sealing lip. The designation 8770Pol is the reference you will find on the manufacturer's product page.

Typical applications for a seal of this size and design are in equipment with large-diameter shafts: gearboxes, speed reducers, centrifugal pumps, medium-power electric motors and belt or chain drives. It is also found in machinery for the food, cement and process industries, where the working environment has dust or moisture. In all these cases it performs the same function: keeping lubricant in and contaminants out.

To install a seal, check that the shaft has no burrs, scratches or wear in the contact area, and that the housing is clean and free of deformation. The lip is lubricated before insertion and pressed in with a flat tool to avoid damaging it. Selection depends on rotation speed, working temperature and the type of fluid to be retained. If the shaft shows wear, consider a seal with an offset lip or a repair sleeve.

If you need an equivalent or a nearby size, send us the code 8770Pol or the dimensions of your shaft and housing. We can look for alternatives within the same DBH line or from other brands we carry, always respecting the dimensions and sealing design. We also advise you if the original seal has a different design and the mounting needs to be adapted. The idea is that you don't have equipment down because you can't find the right seal.
