The DBH 5290Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of contaminants, particles and moisture. With dimensions of 30 mm shaft, 50 mm housing and 10 mm height, and an Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a DBH radial shaft seal, identified by the code 5290Pol. Its dimensions are 30 mm shaft diameter (d), 50 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a seal with a single sealing lip and spring, suitable for rotating lubricated shafts. The lip rides on the shaft and creates a dynamic barrier that retains oil or grease. The outer case is metal, with a coating that facilitates press fitting into the housing.

It is used in applications with rotary motion and a need for sealing: gearboxes, reducers, centrifugal pumps, electric motors, compressors, transmission shafts and process equipment. Also in agricultural, textile, food and transport machinery. It is commonly found in environments with dust, water or vapors, where bearings and lubricant must be protected. Its Lx design provides a balance between sealing and low friction, suitable for moderate peripheral speeds.

To correctly select this seal, verify that the shaft and housing dimensions match those of the equipment. The shaft must be within the recommended tolerance, with a ground surface and no burrs. The housing must have an entry chamfer so the lip is not damaged during installation. Lubricate the lip with the same oil or grease used in the application before installing. Avoid striking the seal: use an installation tube that presses on the metal case, never on the lip. If the shaft shows wear, consider a seal with an offset lip or a repair sleeve.
