The DBH 8959 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles, protecting bearings, bushings and gears. With dimensions of 80 mm shaft diameter, 95 mm housing diameter and 8 mm height, it is press-fitted into the housing and its lip seats on the shaft. It is a key component in pumps, electric motors, reducers and power transmission equipment operating in demanding environments.

This DBH 8959 oil seal has an Lx design, with a sealing lip and stainless steel spring. Its dimensions are 80.00 mm shaft diameter (d), 95.00 mm housing diameter (D) and 8.00 mm height (h). The nitrile elastomer (NBR) resists mineral oils and greases, while the spring maintains constant pressure on the shaft. It is a component of the radial shaft seal category, intended for shafts rotating at moderate and high speeds.

It is used in equipment where lubricant leaks and the entry of contaminants must be prevented. It is common in centrifugal pumps, electric motors, gearboxes, compressors, industrial fans and machine tools. It is also found on transmission shafts, conveyor rollers and process equipment in food, chemical and petrochemical plants. Its design allows efficient sealing in applications with continuous rotary motion.

To install it, check that the shaft has the proper hardness and roughness, with no burrs or marks. Lubricate the lip with the same oil used in the equipment before inserting it. The housing must be clean and undamaged; place the oil seal with a suitable press or tool, applying uniform force on the outer diameter. Avoid striking the lip. If the shaft shows wear, consider a nearby size or an oil seal with an auxiliary lip.
