The DBH 8347 radial shaft seal is a lip seal designed for rotating shafts with a 20 mm diameter, a 30 mm housing bore and a 7 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that could damage bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, creating a reliable dynamic barrier in industrial equipment.

This item is a radial shaft seal from the DBH line, identified by the code 8347. Its dimensions are: shaft diameter 20 mm, housing bore diameter 30 mm and height 7.00 mm. The Lx design corresponds to a seal with a single sealing lip and a metal case, suitable for general applications requiring oil or grease retention. The 8347 designation makes it easy to locate quickly in catalogues and maintenance lists.

Radial shaft seals such as the DBH 8347 are used in gearboxes, pumps, electric motors, compressors and power transmission equipment. Their main function is to prevent lubricant leaks and protect bearings from the entry of contaminants. They are common in machine tools, conveyors and hydraulic systems where the shaft rotates continuously. They are also used in automotive and industrial applications that require cost-effective, efficient sealing.

To select a seal correctly, check that the shaft, housing bore and height dimensions match those of the housing and the shaft. The shaft surface must be ground and free of burrs; a rough finish accelerates lip wear. During installation, lubricate the lip with the same oil or grease used in the equipment and use an installation sleeve to prevent twisting. If the seal replaces another one, compare the design and the lip material.
