The DBH 6309 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —31.75 mm shaft, 50.80 mm housing and 15.87 mm height— make it suitable for equipment with 1 1/4 inch shafts, a common size in agricultural and industrial machinery. MR Accesorios Industriales carries this brand and advises you on choosing the right seal for your application.

This item is a DBH 6309 radial shaft seal, identified by its designation 6309. Its dimensions are: shaft diameter (d) 31.75 mm, housing diameter (D) 50.80 mm and height (h) 15.87 mm. The Mx design corresponds to a configuration with a sealing lip and metal body, intended for press-fit mounting in the housing. It is a sealing component that works in direct contact with the shaft, so its correct selection depends on these three dimensions matching those of the equipment.

Typical applications for a seal such as the DBH 6309 include gearboxes, pumps, electric motors, reducers and power transmission equipment. It is also found in agricultural machinery, such as seeders and combines, where sealing against dust and moisture is critical. In all cases, its function is twofold: prevent oil or grease leaks and block the entry of particles that accelerate wear on bearings and shafts.

To install a DBH 6309 seal, verify that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and use a support tube that transmits force evenly onto the metal body, never onto the lip. If the shaft shows wear, consider a seal with the lip in a different position.

If you need an equivalent, the most practical approach is to send us the complete seal part number, the shaft, housing and height dimensions, and a photo of the old part if you have it. With that data we can look for alternatives within the DBH line or from other brands we carry. Do not improvise with approximate dimensions: a seal that does not fit correctly can fail within a few hours of operation.
