The DBH 6219 radial shaft seal is a lip seal designed for 12 mm rotating shafts, with an 18.10 mm housing bore and a 3.70 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in equipment where axial space is limited and a reliable seal is required at low and medium speeds.

This item is a radial shaft seal from the DBH brand, identified by the code 6219. Its nominal dimensions are: shaft diameter 12 mm, housing bore diameter 18.10 mm and height 3.70 mm. The Lt design corresponds to a single-lip configuration, suitable for applications with grease or oil lubrication and moderate peripheral speeds. The lip elastomer runs on the shaft creating a dynamic seal, while the outer diameter ensures the fit in the housing.

Typical applications for this seal include small electric motors, gearboxes, centrifugal pumps, compressors, machine tools and power transmission equipment. It is also found on fan shafts, conveyor belts and low-pressure hydraulic systems. In all cases, it protects the bearings and prevents lubricant leaks, extending the service life of the assembly and reducing maintenance downtime.

For correct installation, check that the shaft has no burrs or marks and that the sealing surface is polished. Lubricate the lip before inserting it and make sure the housing is clean and free of deformation. Selection must consider rotation speed, operating temperature and the type of fluid to be retained. If the original seal shows premature wear, check shaft alignment and play.
