The 8724Pol from DBH is a radial shaft seal that sits in the housing bore and wipes against a turning shaft, holding lubricant in and keeping dust, water and other contaminants out. Its three working dimensions are a shaft of 80.00 mm, a housing of 100.00 mm and a height of 10.00 mm, and it comes in the Mx-Bidi design. Gearboxes, pumps, electric motors and power transmission assemblies are the usual homes for this size. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the job.

Reading the code is straightforward: 8724Pol is the designation, and the numbers behind it describe where the seal fits. Shaft (d) measures 80 mm, housing (D) measures 100 mm and height (h) measures 10.00 mm. The Mx-Bidi designation points to a double-lip, bidirectional arrangement, so the seal can retain grease or oil while also blocking dust and water coming from outside. Because the lip runs in dynamic contact with the shaft, choosing and fitting it correctly is what keeps leaks and early wear away.

Sizes like these show up in reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In each case the seal keeps lubricant where it belongs and shields bearings and gears from whatever is floating around outside. Agricultural machinery, material handling equipment and process lines running 80 mm shafts are also common places to find it.

Before pressing a new seal in, confirm the bore and shaft are clean and free of burrs or scratches, and that the measurements match 80 mm shaft, 100 mm housing and 10 mm height. Coat the lip with the same oil or grease used in service, then seat the seal square to the shaft with a proper installation tube. Do not strike the lip or its spring. A worn shaft may call for a repair sleeve or a different size.

For an equivalent, send the part number 8724Pol or the three current dimensions along with a photo or the old seal itself. With that we can search the DBH line or other brands we supply and check that design and material line up. We can also tell you whether your application calls for a seal built for high temperatures or aggressive fluids.
