A radial shaft seal built for rotating equipment, the DBH 8069Pol keeps lubricant in and contaminants out at the shaft exit point. It fits a 22.2 mm shaft inside a 40 mm bore, and its 12/17 mm height corresponds to a profile that can sit at either of two housing depths. Pumps, motors, gearboxes and similar transmission assemblies are the usual homes for this seal.

The designation to look for is 8069Pol, and the profile follows an A 148-R design. Reading the size string: shaft 22.2 mm, housing 40 mm, height 12.00/17.00 mm. That dual height figure means the same seal can be pressed into housings of two different depths, as long as the lip still lands correctly on the shaft. Sealing happens at the lip-to-shaft contact, while the outer flange holds the seal in the bore.

Seals of this type belong anywhere a shaft turns and lubricant has to stay put. Centrifugal pumps, electric motors, gearboxes, conveyor rollers, mixers and machine tools all rely on them, and so do agricultural implements and road equipment, where dust and moisture make sealing a real concern. The payoff is straightforward: bearings stay protected and the assembly lasts longer.

Selecting a replacement comes down to three checks: shaft diameter, housing diameter and the height you have to work with. The shaft surface should be ground, without splines or burrs, and a suitable roughness helps the lip seal properly. During installation, coat the lip with the same oil or grease the equipment runs, and drive the seal in with a support tube so the lip is not damaged. A worn shaft may call for a seal with an auxiliary lip. Material choice also depends on the fluid and the operating temperature.

If you are matching an 8069Pol, send the part number along with your shaft and housing dimensions and a photo of the old part. We can search other brands or series for alternatives that share the same critical dimensions, and we can help you settle on the right lip type and material for the job. The more detail you provide, the closer the first proposal will be.
