The DBH 8156 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and exclude dust, water or particles. With a 25.40 mm shaft, 38.07 mm housing and 6.66 mm height, and Mx design, it is a replacement part for equipment with one-inch shafts. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified with code 8156. Its dimensions are: shaft diameter 25.40 mm, housing diameter 38.07 mm and height 6.66 mm. The Mx design corresponds to a single-lip configuration with a spring, suitable for rotating shafts. The seal combines an elastomeric element with a metal reinforcement that gives it rigidity and allows it to maintain interference in the housing. It is used to seal shaft exits in gearboxes, pumps, electric motors and other equipment where there is continuous rotation.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. It is also used in agricultural and industrial machinery where the shaft rotates on bearings and oil or grease leaks need to be prevented. Because of its inch shaft size, it is common in equipment of US origin or in replacements for standardized shafts. If your equipment operates at moderate temperature and peripheral speed within the usual ranges for lip seals, this model can be a direct option.

To mount the seal correctly, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal perpendicular to the shaft using a suitable mounting tube. Avoid hitting the lip or the spring. When selecting a seal, consider the shaft speed, operating temperature and the type of fluid to be retained. If the shaft has a worn track, consider mounting a seal with an offset lip or a repair sleeve.
