The DBH 8731 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block dust, water or particles from entering. Its Lx design and dimensions of 22.22 mm shaft, 35.00 mm housing and 6.40 mm height make it suitable for equipment with small-section shafts where axial space is limited. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH brand radial shaft seal, identified by code 8731. Its dimensions are 22.22 mm shaft diameter, 35.00 mm housing diameter and 6.40 mm height. The Lx design corresponds to a single-lip configuration with spring, intended for rotating shafts with permanent lubrication. The sealing lip runs on the shaft race and the outer case is press-fitted into the bore, so the assembly closes the passage of oil or grease to the outside.

Seals of this type are used in gearboxes, pumps, electric motors, compressors, machine tools and power transmission equipment in general. They also appear in agricultural, road and process applications, where shafts rotate inside a lubricated housing and the lubricant must be contained without adding unnecessary friction. In all these cases, the seal protects bearings and gears from external contamination and prevents oil losses that dirty the equipment and force frequent replacements.

To choose a seal correctly, verify the shaft diameter, housing diameter and available height. It is also advisable to check rotation speed, working temperature and lubricant type, because the elastomer compatibility depends on that. Installation requires cleaning the race, lubricating the lip before inserting it and using a tube or support bushing to avoid damaging the sealing edge. If the shaft shows wear or scratches, the seal may lose effectiveness even if the dimensions match.
