The DBH 5851 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Due to its compact dimensions —28.6 mm shaft, 39.7 mm housing and 4.76 mm height— it is used in equipment where axial space is limited and a reliable seal is required. MR Accesorios Industriales supplies this official brand and advises you so you can choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the code 5851. Its dimensions are: shaft diameter 28.6 mm, housing diameter 39.7 mm and height 4.76 mm. The Lt design indicates a lip configuration that works on the shaft to contain lubricant and block the entry of dust or water. It is a replacement part for assemblies where space is limited and efficient sealing is needed.

Radial shaft seals such as the DBH 5851 are used in gearboxes, pumps, electric motors, compressors and transmission equipment. They also appear in agricultural machinery, conveyors and hydraulic systems. Their function is to prevent oil or grease leaks and protect bearings from the entry of particles, extending the service life of the assembly. They are common in applications with moderate speeds and continuously rotating shafts.

To install a seal, check that the shaft has no burrs or wear and that the housing is clean. Lubricate the lip before inserting it and place the seal perpendicular to avoid damaging it. When selecting, consider speed, temperature and the type of fluid. If the shaft shows a wear groove, evaluate an alternative size or a seal with an offset lip. Correct installation ensures sealing.
