The DBH 1178 is a radial shaft seal with A 378 design, with a housing diameter of 80 mm and a height of 10 mm. This type of seal combines an elastomeric lip with a metal body that is press-fitted into the housing, and its function is to retain lubricant and block the ingress of dust, water or particles.

Radial shaft seals such as the DBH 1178 are used in gear reducers, pumps, electric motors, conveyor rollers and transmission equipment. They are common in applications where a rotating shaft passes through a housing and oil or grease leaks must be prevented. They also appear in agricultural machinery, process equipment and conveying systems, provided that the speed and temperature conditions are compatible with the lip material.

To install a seal, verify that the housing is clean, free of burrs and with adequate roughness. The lip must be lubricated before inserting the shaft, and the installation tool must press on the outer diameter, never on the lip. If the shaft shows wear or grooves, consider a repair sleeve or an alternative location. The final selection depends on peripheral speed, working temperature and the fluid to be retained.
