The DBH 5683 radial shaft seal is a lip seal that is fitted in the housing and closes against the rotating shaft to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 34.92 mm shaft, 53.49 mm housing bore and 15.87 mm height place it in equipment with medium-section shafts. It is a wear part: when the lip hardens or becomes marked, oil loss begins.

This item is a radial shaft seal from the DBH brand, identified by the code 5683. Its dimensions are 34.92 mm shaft diameter, 53.49 mm housing bore diameter and 15.87 mm height. The Lx design corresponds to a single-lip configuration with a spring, intended for rotating shafts with lubrication. The elastomer and the internal spring work together to maintain contact on the shaft and compensate for small misalignments.

Radial shaft seals of this size are used in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. They also appear in agricultural machinery, conveyors and hydraulic systems where oil must be separated from the environment. In all those cases they perform the same function: prevent leaks and protect bearings and gears from the ingress of contaminants.

To install a seal, the condition of the shaft and housing must be checked. The shaft must not have burrs, deep scratches or wear in the contact area; the housing must be clean and free of deformation. It is advisable to lubricate the lip before inserting it and to use an installation tube that bears on the outer diameter, never on the lip. If the shaft shows a wear track, one option is to shift the seal slightly so that the lip runs on a new track.

If you need a nearby size or an equivalent, the most practical approach is to send us the code 5683 together with the shaft, housing and height dimensions. With that data we can look for alternatives in other brands or configurations within the same family. A photo of the old seal and of the area where it is fitted also helps, so we can confirm the design and the type of lip before quoting.
