The DBH 9803 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in equipment with a rotating shaft. Its dimensions of 60 mm shaft diameter, 90 mm housing diameter and 13 mm height place it in a medium-size application, common in pumps, gearboxes and electric motors. MR Accesorios Industriales carries this official brand and advises you so you can choose the right seal for your equipment.

The DBH 9803 is a radial shaft seal with A 111 design, 60 mm shaft diameter, 90 mm housing diameter and 13.00 mm height. The sealing lip runs on the rotating shaft and the outer diameter is press-fitted into the housing. The A 111 designation corresponds to a single-lip geometry with a spring, suitable for shafts with continuous rotation and oil or grease lubrication. It is a wear part: over time the lip hardens or wears and lubricant loss appears.

Seals of this size are used in gearboxes, centrifugal pumps, electric motors, mixers and power transmission equipment. In food, chemical or water treatment plants, the seal serves a dual purpose: it prevents oil from escaping and dust or water from entering the bearing. That is why it is found in equipment where external cleaning is intensive or washing is frequent. It is also common in older machines, where the original seal is no longer easy to find.

To install it, verify that the shaft has no burrs, splines or wear on the sealing surface. The 60 mm diameter must enter without forcing and the 90 mm housing must be clean and free of marks. Lubricate the lip before sliding it on and avoid hitting it: it is installed with a press or support tube, never with hammer blows. If the shaft shows a deep groove, consider a wear sleeve or a nearby size. The 13.00 mm height must match the housing so the seal is not displaced.

If you need an equivalent or a nearby size, send us the part number 9803 along with the shaft, housing and height dimensions shown on your equipment. A photo of the old seal and the housing also works. With that data we review alternatives within the DBH line or other brands we carry, always respecting the geometry of the A 111 design. If space allows, we can consider a seal with a secondary lip or a different material depending on the fluid.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If you already have the part number DBH 9803, write to us on WhatsApp and we will send you the quote. If you are unsure about the size, send the equipment data and we will verify it together.
