The DBH 8872 radial shaft seal is a lip seal that mounts in the housing and seals against the shaft to retain lubricant and block the entry of dust, water or chips. Its dimensions are 22.00 mm shaft diameter, 35.00 mm housing diameter and 7.00 mm height, with Lx design. It is used in pumps, electric motors, gearboxes and power transmission equipment where a shaft rotates inside a fixed housing.

The DBH 8872 is a spring-loaded lip seal, identified by the designation 8872. It runs on a 22 mm diameter shaft, fits a 35 mm housing and has a 7.00 mm height. The Lx design defines the geometry of the lip and the metal case: the flexible lip bears on the shaft and the outer reinforcement is fixed in the housing. That combination of dimensions is what must be matched when replacing it.

Typical applications for this size appear in small centrifugal pumps, low-power electric motors, gearboxes, mixers and power transmission equipment. In every case it performs the same function: keeping oil or grease inside the housing and preventing the environment from reaching the bearing or bushing. It is also found in agricultural machinery and washing equipment, where the seal is the first barrier against water.

To install it, check that the shaft has no burrs or wear on the running surface and that the housing is clean and free of dents. Lubricate the lip before inserting it and push the seal in evenly, without tilting it, until it seats at the bottom. If the shaft shows a deep mark, the new lip will not seal properly: it is worth considering a seal with an offset lip or repairing the running surface.
