The DBH 6219 radial shaft seal is a lip seal built for 12 mm rotating shafts, with an 18.10 mm housing bore and a 3.70 mm height. It keeps lubricant in and dirt, water, and particles out, protecting bearings and bushings from premature wear. This seal suits assemblies where axial space is tight and dependable sealing is needed at low to medium speeds.
This radial shaft seal carries the DBH brand and the code 6219. Its nominal dimensions are: shaft 12 mm, housing bore 18.10 mm, and height 3.70 mm. The Lt design is a single-lip configuration for grease or oil lubrication at moderate peripheral speeds. The elastomer lip runs against the shaft to form the dynamic seal, while the outer diameter holds the fit in the housing.
Common uses include small electric motors, gearboxes, centrifugal pumps, compressors, machine tools, and power transmission equipment. You will also find it on fan shafts, conveyor belts, and low-pressure hydraulic systems. In each case, it shields bearings and stops lubricant leaks, which helps extend assembly life and reduce maintenance downtime.
During installation, confirm the shaft is free of burrs or marks and that the sealing surface is polished. Lubricate the lip before pressing it in, and check that the housing is clean and undistorted. When selecting a seal, account for rotation speed, operating temperature, and the fluid being retained. If the original seal wears early, inspect shaft alignment and play.
