The DBH 6902 is a radial shaft seal with a single lip and spring, sized for a 27 mm shaft, a 37 mm housing bore and a 7 mm height. It keeps oil or grease where it belongs and blocks dust, water and particles from reaching bearings and bushings. Pressed into the housing, its flexible lip runs against the shaft and tolerates slight misalignment. Treat it as a wear item: replace it whenever the assembly is opened.
The code 6902 is a numeric designation that groups the three key dimensions. Shaft 27 mm, housing bore 37 mm, height 7.00 mm. The Lx design means one sealing lip with a spring, which suits rotating shafts. Before installation, confirm that the shaft and housing match these figures.
You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. It also appears in agricultural machinery, washing systems and anywhere dust or water is present. In every case, its job is to hold lubricant inside and shield bearings or bushings from outside contamination. A small part, but one that affects how long rotating components last.
During installation, check the shaft for burrs or marks that could cut the lip, and coat the seal with the same lubricant used in the equipment. The housing must be clean and undistorted. When choosing a seal, consider rotation speed, operating temperature and the fluid being retained. If vibration or misalignment is high, a more flexible design or a double-lip seal may be a better fit.
Need an equivalent? Send code 6902 or the shaft, housing and height dimensions. We will check other brands or alternatives in the same category. We can also tell you whether a different height will fit the space or if a dust-protection design makes more sense. The aim is to match your equipment as closely as possible.

Frequently asked questions
- What are the dimensions of the DBH 6902 seal?
- Shaft 27 mm, housing bore 37 mm, height 7.00 mm. These are the figures that determine fit. Always check them against your shaft and housing before installing.
- What type of shafts is this seal suitable for?
- It is made for rotating shafts where lubricant must stay in and contaminants must stay out. Continuous rotation in gearboxes, pumps and motors is a good match. Avoid it on shafts with excessive axial movement or very high speeds without evaluating the application first.
- How do I request a quote or an equivalent?
- Send code 6902 or the dimensions (shaft, housing, height) via WhatsApp to MR. With that data we will quote the DBH seal or look for an equivalent alternative. You can also ask if the installation needs adapting.
