The DBH 8020 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. It runs on a 47.62 mm shaft, fits a 73.06 mm housing and is 12.70 mm high, with A 187 design. It is used in gearboxes, pumps, electric motors and power transmission equipment where lubricant must be retained and dust or water ingress stopped.

This item is a radial shaft seal from the DBH line, identified by part number 8020 and A 187 design. Its dimensions are 47.62 mm shaft, 73.06 mm housing and 12.70 mm height. The flexible lip bears on the rotating shaft and seals against the housing, so that lubricant stays inside and contaminants stay out. It is a common replacement part in equipment where the shaft is already machined and only the seal is replaced.

Typical applications appear in gearboxes, centrifugal pumps, motors, rollers and drive shafts. In all these cases the seal serves two functions: retaining the oil or grease of the bearing and preventing dust, chips or water from entering. It is also used as a secondary barrier in equipment with moderate vibration, provided the shaft speed and operating temperature match the original design of the assembly.

To install it, check that the shaft has no burrs or marks and that the seating surface is clean and lubricated. The seal is inserted perpendicular to the shaft, without striking the lip, and it is advisable to use an installation tube or bushing of the appropriate diameter. Before choosing a replacement, compare the three dimensions of the record and the lip design: a change in height or profile can prevent the seal from seating properly.
