The DBH 5737 radial shaft seal is a lip seal that mounts on a 79.38 mm shaft and seals against a 107.93 mm housing, with a 19.05 mm height. Its function is to retain lubricant inside the assembly and stop the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and transmission equipment where the shaft rotates continuously and a reliable barrier is needed.

This item is a seal from the DBH line, identified by the code 5737 and the Lx design. The dimensions listed in its data sheet are 79.38 mm shaft, 107.93 mm housing and 19.05 mm height. The Lx design corresponds to a single-lip seal with a metal case and elastomeric lip, intended for rotating shafts with permanent lubrication. Before installing it, verify that the shaft and housing diameters match these values, because a seal that does not seat properly loses effectiveness within a few hours.

Typical applications of this type of seal appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases the seal performs two functions at once: it prevents oil or grease from escaping to the outside and blocks the entry of contaminants. When the seal works on a worn or misaligned shaft, the loss of lubricant and the entry of dirt end up damaging nearby bearings.

To select and install a seal such as the 5737, take into account the shaft rotation speed, the working temperature and the type of lubricant. The lip must be lubricated before start-up and the shaft must be clean, without burrs or deep marks. It is advisable to replace the seal every time the assembly is disassembled, because the lip deforms when it is removed and will not seal the same way again. If the shaft shows a marked groove, consider a nearby size or a seal with the lip in another position.
