The DBH 8003Pol radial shaft seal is a lip seal that is mounted on the shaft and closes against the housing to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 30 mm shaft, 40 mm housing and 7 mm height place it in small and medium-sized equipment, where axial space is limited and a reliable seal is needed. MR Accesorios Industriales sells it as part of its line of seals and oil seals.

This item is an oil seal with an Lx-R design: sealing lip with spring and reinforced body, intended for rotating shafts. The dimensions listed on the product page are 30 mm shaft diameter, 40 mm housing diameter and 7.00 mm total height. Those three dimensions define the mounting: the inner diameter presses onto the shaft, the outer diameter seats in the housing and the height determines how far the seal protrudes. The designation 8003Pol corresponds to the manufacturer's nomenclature DBH.

Typical applications for a seal of this size appear in small centrifugal pumps, low-power electric motors, compact gearboxes, compressors and transmission equipment. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate the wear of bearings and gears. It is also used as a secondary seal in machine tools and continuous process equipment.

To select and install a radial shaft seal, it is advisable to verify that the shaft and housing diameters match the dimensions on the product page, that the shaft surface is polished and free of burrs, and that the lip is oriented toward the side of the fluid to be retained. The 7.00 mm height must fit without deforming the seal. If the shaft is worn, consider a nearby size or a repair sleeve. The working speed and temperature are confirmed against the manufacturer's product page.

If you need an equivalent oil seal or a close size, send us the code 8003Pol or the three dimensions — shaft, housing and height — along with a photo of the housing. At MR Accesorios Industriales we check the designation against the manufacturer's product page and offer alternatives from the same category when the exact size is not available.
