The DBH 6902 radial shaft seal is a lip seal designed for 27 mm rotating shafts, with a 37 mm housing bore and 7 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that could damage bearings and bushings. It is press-fitted into the housing and runs on the shaft with a flexible lip that compensates for minor misalignment. It is a wear part that should be replaced at every teardown to ensure system sealing.

This item is a DBH brand radial shaft seal, identified by code 6902. Its dimensions are: shaft diameter 27 mm, housing bore diameter 37 mm and height 7.00 mm. The Lx design corresponds to a seal with a single sealing lip and spring, suitable for rotating shafts. The 6902 nomenclature is a numeric designation that groups these dimensions; it is always advisable to verify that the housing and shaft match the indicated dimensions before installation.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment in general. In all cases, its function is to confine oil or grease inside the assembly and protect bearings or bushings from external contamination. It is also used in agricultural machinery, washing equipment and systems where dust or water is present. It is a critical part for the service life of rotating components.

For installation, make sure the shaft has no burrs or marks that could damage the lip, and lubricate the seal with the same lubricant used in the equipment before inserting it. The housing must be clean and free of deformation. Seal selection depends on rotation speed, operating temperature and the type of fluid to be retained. If the equipment operates with high vibration or misalignment, consider a more flexible design or a double-lip seal.

The goal is for you to find the part that best suits your equipment.
