The DBH 5888Sil radial shaft seal is a lip seal that mounts in the housing and closes against the rotating shaft to retain lubricant and block dust, water or particles from entering. With dimensions of 55 mm shaft, 80 mm housing and 10 mm height, and an Lx design, it is a frequently replaced part in gearboxes, pumps and transmission equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH 5888Sil radial shaft seal, identified by its commercial designation. Its main attributes are: shaft diameter 55 mm, housing diameter 80 mm and height 10 mm. The Lx design corresponds to a single-lip configuration with a spring, suitable for rotating shafts with lubrication. DBH is a brand MR sells, so the product arrives with its factory identification and traceability. Always verify these three dimensions before replacing an oil seal, because a difference of tenths can cause leaks or a forced fit.

Typical applications for an oil seal of this size include gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and continuous process equipment. In all cases it fulfills the function of retaining the oil or grease inside the assembly and preventing external contaminants from entering. It is also used in rollers, mixers and conveyors where the shaft rotates on bearings and a reliable seal is needed. As it is a wear part, it is advisable to check the lip and spring at any sign of lubricant loss.

To select this oil seal correctly, keep in mind that the shaft diameter must match the wear track and that the housing must not have burrs or scratches. The Lx design allows moderate peripheral speeds and requires a shaft surface with adequate hardness and roughness; if the shaft is marked, consider a repair sleeve. During mounting, lubricate the lip with the same oil used in the equipment, insert the oil seal perpendicularly and avoid striking it directly. A suitable mounting tool reduces the risk of deforming the seal.

If you need an oil seal equivalent to the DBH 5888Sil, the most practical approach is to send us the full code, the brand and the shaft, housing and height dimensions. With that data we can look for an alternative in the same series or in another brand we sell, always respecting the critical dimensions. We can also guide you if the Lx design is not the most suitable for your application and another type of lip or material should be considered. The idea is that you do not end up with equipment down because of a low-cost part.
