This item is a DBH radial shaft seal, identified with designation 5440. Its dimensions are: shaft diameter (d) 127 mm, housing diameter (D) 152.40 mm and height (h) 14.28 mm. The Lz design corresponds to a sealing lip with specific characteristics for applications with moderate dust exposure. The seal is made of oil- and grease-resistant elastomer, with a metal reinforcement that gives it rigidity for press fitting. These dimensions and the lip type make it suitable for shafts rotating at medium speeds and requiring durable sealing.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal prevents lubricant leaks and the entry of abrasive particles that accelerate wear on bearings and gears. It is also used in agricultural and industrial machinery where the environment may contain dust or moisture. Its 127 mm shaft size makes it common in medium- and high-power equipment.

To correctly install a seal such as the DBH 5440, verify that the shaft has adequate hardness and roughness, free of burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The housing must be clean and free of deformation; the seal is inserted with uniform pressure, never by striking the lip. When selecting, consider rotation speed, operating temperature and the type of fluid to be retained. If the shaft shows wear, consider a repair sleeve.
