The DBH 8389 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on 8 mm rotating shafts. Its compact 8.00 x 19.00 x 5.00 mm size and Lt design make it suitable for tight spaces where a reliable barrier against dust, water and oil loss is required. It is used in pumps, electric motors, gearboxes and power transmission equipment operating at moderate speeds and temperatures within the usual range of nitrile elastomers.

This item is a radial shaft seal from the DBH brand, identified by part number 8389. Its nominal dimensions are 8.00 mm shaft diameter, 19.00 mm housing diameter and 5.00 mm height. The Lt design corresponds to a single-lip configuration with a spring, intended for rotating shafts with permanent lubrication. The sealing elastomer and the internal metal spring ensure uniform contact pressure on the shaft, which reduces wear and extends the service life of the component.

Typical applications for this oil seal include small centrifugal pumps, low-power electric motors, speed reducers, compressors and belt- or chain-driven transmission equipment. It is also found in machine tools, refrigeration equipment and hydraulic systems where oil or grease must be contained in a small space. Its compact size makes it suitable for 8 mm shafts rotating at moderate speeds and subject to light vibration.

To correctly select an oil seal such as the 8389, check that the shaft diameter is within the tolerance recommended for radial seals, generally h6 or js6, and that the housing has a suitable surface finish. The 5.00 mm height must match the housing depth to prevent leaks or deformation. During installation, lubricate the lip with the same working fluid, insert the seal perpendicular to the shaft and avoid striking it directly. If the shaft shows wear, consider using a repair sleeve.
