This item is a radial shaft seal from the DBH brand, identified by the code 6420. Its standard dimensions are: shaft diameter (d) 50.80 mm, housing diameter (D) 70.26 mm and height (h) 16.66 mm. The Lx design corresponds to a seal with a single sealing lip and spring, suitable for applications where the shaft rotates and an effective barrier against oil or grease leaks is required. The 6420 designation makes it easy to locate quickly in catalogs and ordering systems.

Radial shaft seals such as the DBH 6420 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their ability to withstand moderate peripheral speeds and low pressures makes them suitable for environments with continuous lubrication. They are also used in agricultural machinery, conveyors and hydraulic systems where lubricant must be contained and bearings protected from external contamination.

To select a seal correctly, verify that the shaft and housing dimensions match those of the seal. The Lx design indicates a lip with a spring that guarantees constant contact on the shaft. It is essential that the shaft surface be ground and free of burrs, and that the housing have an entry chamfer so the lip is not damaged during installation. Lubricate the lip before inserting it and make sure it sits perpendicular to the shaft.
