The DBH 8278 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. With dimensions of 50 mm shaft diameter, 62 mm housing diameter and 7 mm height, and an Lz design, it is used in pumps, motors, gearboxes and industrial equipment in general. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified with part number 8278. Its dimensions are 50.00 mm shaft diameter (d), 62.00 mm housing diameter (D) and 7.00 mm height (h). The Lz design corresponds to a configuration with a sealing lip and dust lip, suitable for applications with moderate exposure to contaminants. The elastomer and the internal spring guarantee sealing under continuous rotation conditions. It is important to verify that the dimensions match the shaft and housing before installation.

Typical applications for this seal include centrifugal pumps, electric motors, gearboxes, reducers and power transmission equipment. It is also used in agricultural machinery, process equipment and hydraulic systems where oil or grease must be contained and bearings protected. Its size of 50 x 62 x 7 mm is common on medium-diameter shafts, making it a frequent size in industrial maintenance. If your equipment operates at moderate peripheral speeds and controlled temperature, this seal is a reliable option.

To correctly select a seal, take into account the shaft rotation speed, operating temperature, type of lubricant and differential pressure. The Lz design offers an additional barrier against dust, but if the environment is very aggressive it may require a seal with a double lip or special materials. During assembly, lubricate the lip with the same oil or grease used in the application, insert it perpendicular to the shaft and avoid striking it. Careful installation extends the service life of the seal and protects the internal components.
