The DBH 8921 radial oil seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. Due to its dimensions of 48 mm shaft, 70 mm housing and 10 mm height, and its Lx design, it is used in gearboxes, pumps, electric motors and transmission equipment that need reliable sealing and simple replacement.

This item is a DBH 8921 radial shaft seal, identified by its designation 8921. Its dimensions are 48 mm shaft diameter, 70 mm housing diameter and 10 mm height. The Lx design corresponds to a seal with a sealing lip and a construction configuration specific to the series. The flexible lip works on the shaft and, aided by the internal spring, maintains contact to contain the oil or grease and stop the entry of contaminants.

It is used in equipment where a shaft rotates inside a lubricated housing: gearboxes, centrifugal pumps, electric motors, rollers and belt or chain drives. It also appears in mixers, fans and machine tools. In all cases it performs the same function: separating the lubricated interior from the outside environment and extending the life of bearings and gears.

To install it, check that the shaft diameter and the housing diameter match the indicated 48 mm and 70 mm, and that the 10 mm height fits into the cavity. The shaft must be clean, without burrs or marks, and the housing free of deformation. Lubricate the lip before inserting it and avoid striking it during installation. If the shaft shows wear, consider a neighbouring size or a seal with an additional lip.

If you need an equivalent or a different size, send us the code 8921 or the dimensions of the original seal. With that data we look for alternatives in the same series or in other brands we carry. We can also guide you if the housing or the shaft have unusual tolerances, in order to choose the right lip design and material.
