This item is a radial shaft seal from the DBH brand, identified with part number 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. It is manufactured with elastomers and metal reinforcements that give it resistance to wear and temperature, although the exact materials and operating ranges are not specified in this record.

Typical applications for this seal include gearboxes, pumps, electric motors, drive 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 reliable sealing is essential to avoid unplanned downtime.

To install this seal correctly, verify that the shaft and housing diameters match the dimensions indicated. 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.
