This item is a radial shaft seal from the DBH brand, identified with the code 5559. Its dimensions are 79.38 mm shaft diameter (d), 115.85 mm housing diameter (D) and 30.16 mm height (h). The A 089 design corresponds to a specific lip and case configuration that ensures effective sealing under rotation conditions. It is manufactured with elastomers and metal reinforcements that give it resistance to wear and temperature.

Typical applications of this seal include gearboxes, pumps, electric motors, transmission shafts and continuous process equipment. In these systems, the seal prevents the loss of oil or grease and the entry of dust, water or particles, protecting bearings and gears. It is commonly found in machinery in the food, chemical, petrochemical and general manufacturing industries, where sealing reliability is essential to avoid unscheduled downtime.

To correctly install this seal, verify that the shaft and housing diameters match the indicated dimensions. The shaft surface must be free of burrs, with adequate roughness and a hardness that prevents premature lip wear. Lubricate the lip before installation and use an installation tool that applies uniform force so as not to damage it. If the equipment operates at high speeds or temperatures, consult MR to evaluate an alternative design.
