The DBH 5879 radial shaft seal is a lip seal designed to close off the passage of oil or grease at the point where a shaft rotates inside a housing. Its function is to retain the lubricant and, at the same time, prevent the entry of dust, water or particles that could damage bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with 50.8 mm shafts. MR Accesorios Industriales carries this official brand and advises you on choosing the right seal.

This item is a radial shaft seal from the DBH brand, identified with part number 5879. Its dimensions are 50.8 mm shaft, 68.97 mm housing and 11.11 mm height. The Lz design corresponds to a lip and case configuration intended for lubricant retention in rotating applications. Before installing it, verify that the three dimensions match your equipment's shaft and housing, because even a minimal difference prevents correct sealing.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain drive equipment. In all cases it works on a rotating shaft and inside a fixed housing, separating the lubricated interior from the outside environment. It is also found in agricultural machinery, pumping equipment and process lines where dust or moisture must be kept out.

To select and install a radial shaft seal, take into account the shaft diameter, the housing diameter and the available height. The lip must rest on a shaft surface free of splines and burrs, and it should be lubricated before being inserted. The housing must be clean and free of deformation. If the shaft shows wear in the contact area, consider a neighboring size or a seal with the lip in a different position to avoid leaks.

If you need an equivalent or a size close to the 5879, the most practical approach is to send us the dimensions of your shaft, housing and height, along with a photo of the old seal or the part number marked on the part. With that data we can look for alternatives within the same brand or others we carry, always respecting the mounting dimensions.
