The DBH 8209 is a radial shaft seal that sits in a housing and runs against a rotating shaft, keeping lubricant in and contaminants out. Its dimensions are 30.00 mm shaft, 41.00 mm housing and 10.00 mm height, with an Mx-R lip configuration. This makes it a suitable replacement for medium-section shafts in a range of industrial equipment.
The 8209 designation identifies this seal within the DBH line. It is a rotary lip seal: the outer body presses into a machined cavity, while the lip contacts the shaft to form a barrier. The Mx-R design refers to how the lip and body are constructed. Its job is to retain oil or grease and to block dust, water and particles from reaching the bearings.
Typical installations include gearboxes, pumps, electric motors, drive shafts and process machinery where a shaft turns inside a housing and the lubricant must stay separated from the surroundings. In dusty, wet or chip-prone areas, the lip helps protect bearings and supports the service life of the assembly. Because it is a wear part, it is replaced when lubricant starts escaping or contamination gets in.
Before fitting, make sure the shaft is clean and free of burrs or marks, and that the sealing surface is not deeply worn. The housing should be undamaged and at the correct diameter. Lubricate the lip, press the seal in squarely and keep it perpendicular to the shaft. If the shaft has a pronounced groove, you may need to reposition the seal slightly or replace the shaft. Speed, temperature and lubricant type all affect the choice.
To request a quote for an equivalent, provide the code 8209 or the dimensions 30.00 x 41.00 x 10.00 mm along with the Mx-R design. With that information we can search for alternatives in the DBH line or other brands we supply, matching the geometry and lip type. We can also help if your housing or shaft tolerances fall outside the usual range.

Frequently asked questions
- Can I request a different size or an equivalent?
- Yes. Send the code 8209 or the dimensions you need via WhatsApp or email and we will look for an alternative in the DBH line or other brands we carry. If you have the old seal, a photo or caliper measurements help.
- What are the dimensions of the DBH 8209 seal?
- The DBH 8209 seal has a 30.00 mm shaft diameter, a 41.00 mm housing diameter and a 10.00 mm height. The design is Mx-R. Verify these dimensions before installing it.
- How do I know if this seal replaces the one I have installed?
- Compare the shaft diameter, the housing diameter and the height. If they match 30.00 x 41.00 x 10.00 mm, the seal is dimensionally compatible. Also check the condition of the shaft and housing, because wear can affect sealing.
