The DBH 9421 is a radial shaft seal engineered to keep lubricants in and contaminants out where a rotating shaft meets a stationary housing. Its single-lip design with a metal case suits press-fit installation in cylindrical bores. This seal is a common choice for gearboxes, pumps, electric motors, and other power transmission equipment.

Key dimensions for this seal are: shaft diameter 38.00 mm, housing diameter 54.00 mm, and width 10.00 mm. Always confirm these measurements on your equipment before ordering a replacement. The part number 9421 identifies a single-lip seal with metal reinforcement, built for moderate speeds and standard operating conditions.

Typical applications include gearboxes, centrifugal pumps, electric motors, conveyor rollers, and machine tools. In these systems, the seal retains oil or grease while blocking dust, wash water, or metal chips. If your equipment runs in a dirty environment, inspect the seal lip regularly for wear or damage.

For proper selection, consider shaft speed, operating temperature, and lubricant type in addition to dimensions. During installation, lubricate the lip, ensure the shaft is free of burrs or scoring, and press the seal squarely using a suitable driver. Even a correctly sized seal will leak if the lip is damaged or the shaft surface is rough.

If you need an equivalent, send the shaft diameter, housing diameter, and width—or the code from the old seal. A photo of the part and its housing also helps. Our team will check options within the DBH line and other brands we supply, keeping your critical dimensions in mind.
