The DBH 5105 radial shaft seal is a lip seal mounted in the housing that seals against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 22.22 mm shaft, 38.07 mm housing and 9.92 mm height place it in equipment with small-section shafts, such as pumps, electric motors, gearboxes and transmission cases. It is a wear part: when the lip hardens or a leak appears, it is replaced.

This item is a DBH brand oil seal, identified with the code 5105. Its dimensions are 22.22 mm shaft diameter, 38.07 mm housing diameter and 9.92 mm height. The Lz design corresponds to a seal with a sealing lip and standard mounting configuration for cylindrical housing. The lip elastomer works on the shaft with slight interference, and the internal spring maintains contact pressure throughout its service life. The outer metal case ensures a firm fit in the housing.

Typical applications for a seal of this size include small centrifugal pumps, low-power electric motors, speed reducers, compressors, machine tools and power transmission equipment. In all cases it performs the same function: separating the lubricated side from the environment, preventing oil or grease leaks and the entry of contaminants that accelerate wear of bearings and gears. It is also used on fan, mixer and conveyor shafts.

To install a seal, verify that the shaft has no burrs, deep scratches or wear in the contact area, and that the housing is clean and free of deformation. It is advisable to lubricate the lip before inserting it and use an installation tube that presses on the case, never on the lip. Selection depends on shaft speed, working temperature and the fluid to be retained; if the original seal fails frequently, it may be worth evaluating another lip material or a design with a dust lip.

If you need an equivalent or a neighboring size, the most practical approach is to send us the code 5105 along with the shaft and housing dimensions, a photo of the part and, if possible, the equipment drawing or data sheet. With that data we can look for alternatives within the same series or other brands we carry, always respecting mounting tolerances. We can also advise you if the space allows a seal of a different height.
