The DBH 8872 is a radial shaft seal of the lip type, built to sit in a housing and run against a rotating shaft. It keeps lubricant where it belongs and keeps contaminants out. The three dimensions that matter are shaft 22.00 mm, housing 35.00 mm and height 7.00 mm, and the Lx design describes how the lip and the metal case are formed. You will find this seal in pumps, motors, gearboxes and other power transmission assemblies where a shaft turns inside a stationary housing.
Reading the code is straightforward: 8872 is the designation, and the size follows the shaft-housing-height sequence. So the seal runs on a 22 mm shaft, presses into a 35 mm bore and measures 7.00 mm tall. The Lx design covers both the flexible lip that contacts the shaft and the outer metal reinforcement that holds the seal in the housing. When you replace one, all three dimensions plus the design must line up.
This size shows up in small centrifugal pumps, low-power electric motors, gearboxes, mixers and power transmission units. In each case the job is the same: hold oil or grease in and keep dust, water and chips out, protecting the bearing or bushing behind it. Agricultural machinery and washing equipment also use it, since there the seal is the first line of defense against water.
Installation calls for a clean, undamaged shaft surface and a housing free of dents or burrs. Put a little lubricant on the lip, then press the seal in straight, without tilting, until it bottoms out. If the shaft has a deep groove where the old lip ran, a new seal may not seat properly; in that case consider an offset-lip seal or rework the running surface.
If code 8872 is not what you need, we can search for a seal with the same shaft, housing and height. Send the three dimensions along with the fluid and operating temperature, and we will review the options available from the brands we supply.

Frequently asked questions
- What are the dimensions of the DBH 8872 oil seal?
- Shaft 22.00 mm, housing 35.00 mm and height 7.00 mm, with Lx design. These three measurements determine whether the seal fits your equipment.
- How do I request an equivalent if I can't get the code 8872?
- Send the shaft diameter, housing diameter and height by WhatsApp, plus the fluid and working temperature. With those details we can find a seal from another manufacturer that does the same job.
- What should I check before installing a radial shaft seal?
- Make sure the shaft has no burrs or wear, the housing is clean and not deformed, and lubricate the lip before fitting. Press it in evenly all the way to the bottom so the lip contacts the running surface correctly.
