The DBH 8331 is a radial shaft seal built for rotating equipment where keeping lubricant in and contaminants out is essential. With a 20 mm shaft diameter, 32 mm housing diameter, and 7 mm height, this lip seal fits common industrial housings. The Lx design defines its lip and outer body geometry, which affects installation and sealing behavior. It serves in pumps, motors, gearboxes, and similar machinery where reliable sealing protects bearings and gears.
Part number 8331 from DBH identifies this radial shaft seal. Its key dimensions are shaft 20 mm, housing 32 mm, and height 7.00 mm. The Lx designation describes a particular lip and case configuration. The seal combines an elastomeric lip with a metal case for wear resistance and stability. Selection should match the shaft speed, temperature, and fluid in the application.
Common uses include centrifugal pumps, electric motors, speed reducers, compressors, and power transmission units. In these systems, the seal prevents oil or grease loss and blocks dust, water, and other contaminants from reaching bearings and gears. It also appears in machine tools, food processing equipment, and hydraulic systems where sealing integrity directly affects component life.
For installation, clean the shaft and housing bore, removing any burrs. Apply a thin film of the operating lubricant to the seal lip. Press the seal squarely into the housing using a tool that contacts only the outer diameter. Do not strike the lip. After installation, check that the seal is seated evenly to avoid early leakage.
