The DBH 5197 is a radial shaft seal built to hold lubricant in and keep contaminants out where a shaft turns. It measures 52.40 mm at the shaft, 80.00 mm at the housing bore and 6.35 mm in height, and it comes in the Lt design. You will find it in gearboxes, pumps and other industrial equipment where the axial envelope is tight. An elastomer sealing element with a metal case keeps the seal seated and working through continuous duty.

Reading the code helps when you are matching a seal on the bench. The DBH 5197 designation carries its own numeric reference, and the three figures that follow describe the fit: shaft 52.40 mm, housing 80.00 mm, width 6.35 mm. The Lt design points to a single lip with a spring, a configuration chosen where friction and wear need to stay low. The sealing element is nitrile (NBR), which handles mineral oils and greases, and the steel reinforcement gives the outer case its rigidity.

Gearboxes, centrifugal pumps, electric motors and conveyor rollers are the usual homes for this seal. In each of them the DBH 5197 keeps oil where it belongs and blocks dust and moisture from reaching the internals, which protects bearings and gears over the long run. Production lines, treatment plants and agricultural machinery are common places to find it, since a failed seal there means unplanned downtime.

Installation rewards a little care. Check that the shaft surface has the right hardness and a controlled roughness, and that the housing bore is clean and free of burrs. Coat the lip with the same oil the equipment uses before you press the seal in, and drive it with a tool that puts even pressure on the outer diameter. Do not strike the lip or the spring. When selecting, weigh peripheral speed, operating temperature and how the elastomer reacts to the fluid being sealed.
