The DBH 8077Pol radial shaft seal is a lip seal designed to close off the passage of oil or grease at the point where a shaft rotates inside a housing. Its function is to retain lubricant and, at the same time, stop dust, water or particles from entering and wearing down bearings and bushings. It is press-fitted into the housing and works on the shaft with a flexible lip that compensates for small misalignments and vibrations typical of equipment in operation.

This item is a DBH 8077Pol radial shaft seal with the following dimensions: shaft diameter 76.2 mm, housing diameter 101.8 mm and height 11.00 mm. The design indicated by the manufacturer is Mx-Hel, a lip configuration that combines sealing and retention capacity in applications with continuous rotation. The code 8077Pol uniquely identifies this size within the DBH line, so it is best to quote it in full when making an inquiry.

Seals of this size are used in gearboxes, pumps, electric motors, transmission equipment and process machinery where the shaft rotates on lubricated bearings or bushings. They also appear in agricultural, road and material handling applications, where a dust-laden environment demands a reliable seal. If the equipment operates with splashes or frequent washdowns, the seal is the first barrier that protects the lubricant and extends the life of the rotating assembly.

To select a seal properly, the size alone is not enough: you must check the rotation speed, operating temperature, type of lubricant and the condition of the shaft surface. A scratched or worn shaft prevents the lip from seating evenly and leakage appears even if the seal is new. During installation, lubricate the lip before inserting it, place the seal perpendicular to the shaft and use a tube or press that bears on the metal edge, never on the lip.

Send us the dimensions of the old seal: shaft diameter, housing diameter and height. With those three data points we look for the equivalent in DBH or another brand, respecting the lip design. We can also evaluate variants with a spring or with a double lip depending on the service. The more complete the equipment information, the more accurate the proposal.
