DichtungLager
Dichtungslager, commonly translated as seal-bearing, is a term in mechanical engineering describing a bearing assembly that incorporates a sealing element to retain lubricant and protect the bearing from contaminants. The concept covers units in which a rolling bearing is paired with a shaft seal, labyrinth seal, or mechanical seal, either integrated into the bearing ring or mounted in the housing as a matched assembly. The seal serves to prevent oil or grease from leaking and to keep dirt and moisture from entering the bearing.
Configurations and types include integrated-seal bearings in standard bearing series, such as deep-groove or angular-contact bearings
Applications include automotive wheel hubs, electric motors, pumps, gearboxes, and industrial machinery where compact seal solutions
Design considerations encompass load and speed, shaft misalignment, housing rigidity, seal wear, lubricant life, thermal expansion,
Maintenance involves monitoring for leaks, abnormal temperature rise, or seal wear. Depending on design, seals may
