The DBH 5105 is a radial shaft seal that fits into a housing and runs against a rotating shaft. Its job is to keep lubricant in and contaminants out. With a 22.22 mm shaft, 38.07 mm housing and 9.92 mm height, it suits small-shaft equipment such as pumps, motors, gearboxes and transmission cases. As a wear part, it gets replaced when the lip hardens or leaks appear.

This oil seal carries the DBH brand and the code 5105. The dimensions are shaft 22.22 mm, housing 38.07 mm, height 9.92 mm. The Lz design refers to a sealing lip and a standard mounting arrangement for a cylindrical housing. The lip elastomer runs on the shaft with slight interference, while the internal spring keeps contact pressure over time. The outer metal case holds the seal firmly in the housing.

Seals of this size are common in small centrifugal pumps, low-power electric motors, speed reducers, compressors, machine tools and power transmission equipment. They also appear on fan, mixer and conveyor shafts. In every case the function is the same: isolate the lubricated side from the environment, stop oil or grease from escaping and keep out particles that would speed up bearing and gear wear.

When installing, check the shaft for burrs, deep scratches or wear in the contact area, and make sure the housing is clean and undistorted. Lubricating the lip before insertion helps, and an installation tube should press on the case, not the lip. Selection depends on shaft speed, operating temperature and the fluid being retained. If the original seal fails often, consider a different lip material or a design with a dust lip.

For an equivalent, send the code 5105 together with the shaft and housing dimensions, a photo of the part and, if available, the equipment drawing or data sheet. With that information we can search within the same series or other brands we supply, always matching mounting tolerances. We can also tell you whether the space allows a seal of a different height.
