MR Accesorios Industriales supplies this official brand and advises you so you choose the correct seal.

This item is a radial shaft seal from the DBH brand, identified by the code 5086Sil. Its dimensions are: shaft diameter (d) 20 mm, housing diameter (D) 40 mm and height (h) 7.90 mm. The Lx design corresponds to a specific construction configuration within the DBH seal line. It is manufactured with elastomers and a metal case that give it elasticity and wear resistance. It is used to seal rotating shafts in a wide variety of equipment.

Typical applications of this seal include centrifugal pumps, electric motors, gear reducers, gearboxes and conveyor rollers. In all these cases, the seal prevents oil or grease leaks and protects the bearings from dust and moisture. It is a wear part that should be replaced when lubricant leaks or abnormal shaft noises are detected. It is also used in agricultural equipment and continuous process machinery.

To install the seal correctly, verify that the shaft and housing are clean and free of burrs. Lubricate the lip with the same grease or oil used in the equipment before inserting it. Pressure must be applied evenly on the metal face, never on the lip. It is essential that the shaft and housing dimensions match those of the seal; if there is wear on the shaft, consider a repair or a seal with greater interference. The selection depends on speed, temperature and type of lubricant.
