The DBH 6911 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —50.37 mm shaft diameter, 79.90 mm housing diameter and 6.85 mm height— correspond to a specific application, so it is essential to verify that they match your mechanism before replacing it. DBH is a brand that MR carries, with options for different speed and temperature requirements.

This item is a DBH 6911 radial shaft seal, identified by its numeric designation. According to the product page data, the shaft diameter is 50.37 mm, the housing diameter is 79.90 mm and the height is 6.85 mm. The A 012 design corresponds to a single-lip configuration with a spring, suitable for rotating shafts with lubrication. These dimensions are what define interchangeability: a seal with a different height or diameter will not seat correctly and will fail in service.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors and transmission equipment where oil or grease must be contained and dust or water kept out. In industrial plants, it is commonly found in process lines, conveyors and continuous-motion machinery. The choice of lip material and elastomer depends on the working temperature and the fluid to be retained, so it is advisable to confirm those data before ordering the replacement.

For installation, check that the shaft has no burrs or excessive wear in the contact area; a scratched shaft accelerates lip failure. Lubricate the seal before inserting it and use an installation tool that presses on the outer diameter, never on the lip. The 6.85 mm height must match the housing depth so that the seal sits flush or slightly recessed. If the housing has a pronounced chamfer, make sure the seal does not deform as it goes in.

If you need a nearby size or an equivalent, the most practical thing is to send us the code 6911 or the current dimensions of your shaft and housing. With that data we can look for alternatives in the same series or in other brands we carry, always respecting the housing tolerances. We can also advise you on the type of lip and material according to the fluid and operating temperature. You do not need to have the seal on hand: the shaft dimension alone is enough to guide the search.
