The DBH 8390 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its designation corresponds to a seal with a 16 mm shaft diameter, 26 mm housing diameter and 5 mm height, with Lx design. It is used in pumps, electric motors, gearboxes and power transmission equipment where axial space is limited and a reliable seal is required.

The DBH 8390 is a single-lip radial shaft seal with the following dimensions: shaft (d) 16 mm, housing (D) 26 mm and height (h) 5.00 mm. The Lx design indicates a lip and body configuration that fits housings without special machining. The sealing lip runs on the shaft with controlled interference, while the outer diameter maintains the fit in the housing. It is a common replacement part in equipment where oil or grease must be contained and external contamination prevented.

Typical applications for this seal include small electric motors, centrifugal pumps, speed reducers, compressors, machine tools and belt or chain drive equipment. It is also found on fan, mixer and conveyor shafts. In all cases it serves to separate the lubricant from the environment, extending the life of bearings and gears. Its compact size makes it suitable for tight spaces where a larger-section seal will not fit.

To install the seal, check that the shaft measures 16 mm and the housing 26 mm, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and install the seal with a press or suitable tool, applying uniform force on the outer diameter. Avoid striking the lip. If the shaft shows wear, consider a seal with an auxiliary lip or a wear sleeve. Selection must take into account speed, temperature and the type of fluid to be retained.
