When a rotating shaft needs to hold lubricant in and keep dust, wash water or grit out, a radial shaft seal does the job. The DBH 8652 is one of those seals: the lip runs against the shaft while the outer body stays fixed in the housing. It fits a 30 mm shaft, a 50 mm housing and a 7 mm width, so it belongs to the compact, general-purpose range. Treat it as a wear part and plan to swap it once oil starts seeping, the lip feels hard or the shaft shows marks.

Code 8652 describes the metric size combination inside the DBH line, which means you can order the exact replacement without measuring the old seal. The dimensions are: shaft 30 mm, housing 50 mm, width 7.00 mm. The Lz design is a single lip with a spring, made for rotating shafts lubricated with oil or grease.

You will find seals like this one in gearboxes, centrifugal pumps, electric motors, conveyor rollers, mixers and transmission equipment. They also suit setups where two environments have to stay apart, such as oil on one side and dust or wash water on the other. In every case the shaft turns, the housing does not, and the seal keeps the two sides separated.

Before pressing the new seal in, clean the shaft and remove burrs or splines that could nick the lip, then coat the lip with lubricant. Seat it with a tube or spacer that pushes on the metal outer edge, never on the lip itself. If the shaft surface is worn, a seal with a displaced lip is worth considering. Speed, temperature and the lubricant in use all influence the final choice.

For an equivalent, send code 8652 or the three measurements of the old seal: shaft, housing and height. With that we check the DBH line and other compatible options. We can also tell you whether a worn housing or shaft calls for a different size. Quotes go out over WhatsApp from the code or a photo of the part.
