The DBH 9721Pol radial shaft seal is a lip seal mounted between a rotating shaft and its housing to retain lubricant and stop dust, water or particles from entering. Because of its dimensions —76.20 mm shaft, 101.65 mm housing and 11.00 mm height— it is used in gear reducer boxes, pumps and medium-size power transmission equipment. Its Kx-R design combines a sealing lip with a dust lip, which makes it suitable for environments with moderate dirt.

The 9721Pol is a seal with a Kx-R design and the following dimensions: shaft diameter 76.20 mm, housing diameter 101.65 mm and height 11.00 mm. The main lip works on the shaft and the secondary lip, facing outward, stops contaminants from entering. This double-lip configuration is common in equipment operating in plants with dust or humidity, where a single seal is not enough to protect the lubricant.

It is found in gearboxes, centrifugal pumps, mixers, chain conveyors and belt or chain drive equipment. It is also used in machine tools and process equipment where the shaft rotates at moderate speeds and there is a risk of particles entering. It is a wear part: when lubricant loss or dirt ingress appears, it is replaced with an equivalent size and design.

To select it, check that the three dimensions match the housing and the shaft: 76.20 x 101.65 x 11.00 mm. Check the condition of the shaft —free of burrs, without wear and with suitable roughness— and the housing entry chamfer, so as not to damage the lip during installation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or spacer that presses on the outer ring, never on the lip.

To quote the 9721Pol, send us the code and the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we look for the equivalent in the same brand or in another with similar performance. We evaluate alternatives with a single lip or with a dust lip depending on the type of contamination in the equipment.
