The DBH 9389 radial shaft seal is a lip seal designed for rotating shafts with a 27 mm diameter, a 45 mm housing and an 8 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and works on the shaft surface, which must be ground and lubricated. It is a common replacement part in pumps, electric motors, gear reducers and transmission equipment.

This item is a radial shaft seal from the DBH line, identified with the code 9389. Its dimensions are 27 mm shaft, 45 mm housing and 8.00 mm height. The Lx design corresponds to a single lip seal with spring, suitable for rotating shafts in applications where oil or grease tightness is a priority. The designation 9389 makes it easy to locate in the catalog and compare with other brands that use the same numbering. If you need to confirm the lip material or spring type, we verify it against the manufacturer's product page before quoting.

Typical applications of a 27x45x8 mm oil seal include centrifugal pumps, low and medium power electric motors, gearboxes, compressors, mixers and belt or chain transmission equipment. It is also used in machine tools, industrial washing machines and hydraulic systems where a shaft rotates inside a housing and the lubricant must be separated from the environment. In all cases, the seal protects the bearings and extends the service life of the assembly.

To mount this seal, verify that the housing has the correct diameter and chamfer, and that the shaft has no burrs, scratches or wear on the sealing track. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and install the seal with a press or a support tube that rests on the outer ring, never on the lip. If the shaft has a groove or a shoulder, the lip must face the lubricant side. Selection depends on speed, temperature and the fluid to be retained.

We can also search by application: if you tell us the equipment, fluid and working temperature, we can guide the selection.
