The DBH 8056 radial shaft seal is a lip seal for rotating shafts that prevents oil or grease leakage and keeps dust and water out of the bearing. With its dimensions of 30 mm shaft, 55 mm housing and 12 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment. Its Lx-Hel design combines a sealing lip with a helical spring that maintains pressure on the shaft. MR Accesorios Industriales carries this brand and advises you on choosing the right seal.

The DBH 8056 is a spring-loaded lip seal, identified by its 8056 designation. Its dimensions are 30 mm shaft diameter (d), 55 mm housing diameter (D) and 12 mm height (h). The Lx-Hel design indicates a sealing lip with a helical spring, intended for rotating lubricated shafts. The elastomer lip rests on the shaft and the spring compensates for wear and thermal variations. The outer body is metal for a firm fit in the housing.

It is used in equipment where a shaft rotates inside a lubricated housing: gearboxes, centrifugal pumps, electric motors, compressors, mixers and conveyors. It also appears in agricultural machinery, such as seeders and combine harvesters, and in road equipment. In all cases it serves to retain the lubricant and block the entry of contaminants, extending bearing life and reducing maintenance.

To select the seal, verify that the shaft diameter is within the recommended tolerance and that the housing has the right diameter and depth. The shaft surface must be ground and free of grooves so as not to damage the lip. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the shaft shows wear, consider a repair sleeve or a seal with an offset lip.

If you need a different size, a special material or an equivalent from another brand, send us the 8056 code or your seal dimensions on WhatsApp. We can look for an alternative with the same dimensions or a neighboring size, always confirming the application and the type of lubricant. We also advise you on the most suitable lip design according to speed and operating temperature.
