The DBH 1371Pol radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating shaft assemblies. It measures 40 mm shaft diameter, 75 mm housing bore and 10.80/15.50 mm height. The A 296 design pairs a sealing lip with a spring and an outer body that presses into the housing. You will find it in gearboxes, pumps, electric motors and power transmission equipment.

This seal belongs to the DBH line and carries the designation 1371Pol. The dimensions break down as follows: d = 40 mm shaft, D = 75 mm housing bore, h = 10.80/15.50 mm. The A 296 configuration is a single lip with spring, built for rotating shafts where oil or grease retention and protection against dust and water are needed. The two height values point to a stepped profile or a thicker section that can sit against a housing shoulder.

Where does it go? Gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and belt or chain drive equipment. In each case the seal stops lubricant from escaping and blocks external particles from getting in, which helps bearings and gears last. It shows up in industrial machinery, process equipment and heavy-duty vehicles where sealing has to hold up under demanding conditions.

Installation notes: confirm the shaft is 40 mm and free of burrs or scratches, and that the 75 mm housing is clean and undistorted. Lubricate the lip with the same oil or grease used in the equipment, then seat the seal with a press or suitable tool, applying even force on the outer diameter. Do not strike the sealing lip. If the shaft is worn, look at a repair sleeve or a different size.
