The DBH 9309 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and prevent the entry of dust, water or particles. With dimensions of 12 mm shaft, 28 mm housing and 7 mm height, and Lx design, it is a common replacement part in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales carries this official brand so you can replace with the exact size.

This item is a DBH 9309 radial shaft seal, identified by its designation 9309. Its main attributes are: shaft diameter 12 mm, housing diameter 28 mm, height 7.00 mm and Lx design. The Lx design corresponds to a single-lip seal with a spring, suitable for rotating shafts with lubrication. These are the dimensions you must verify against the shaft and housing before ordering, because a seal with a different height or diameter will not seal correctly.

Typical applications of a 12 x 28 x 7 mm oil seal include small centrifugal pumps, low-power electric motors, gear reducers, compressors, machine tools and power transmission equipment. In all cases it fulfills the function of confining the oil or grease inside the assembly and blocking the entry of external contaminants. It is a wear part: when a lubricant leak or abnormal vibration appears, it should be replaced with one of the same size.

To mount this oil seal, verify that the shaft is 12 mm and the housing is 28 mm, with the 7.00 mm height available. The shaft surface must be clean, free of burrs and deep marks, and the housing free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows wear, evaluate an alternative size or a seal with an auxiliary lip.

If you need an equivalent or a nearby size, the most practical thing is to send us the part number 9309 or the set of dimensions 12 x 28 x 7 mm. You can also send us a photo of the old seal or the housing drawing. At MR Accesorios Industriales we check the designation against the manufacturer's product page to offer you the option that best fits your equipment. If the Lx design is not the right one, we propose the corresponding variant.
