The DBH 8109/85 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating shafts. With a 24 mm shaft diameter, 34.4 mm housing diameter and a height of 15.00/19.50 mm, it is press-fitted into crankcases, covers and gearboxes. Its A 110 design combines a sealing lip with a metal case that gives it rigidity and centering. It is a wear part: it should be replaced every time the assembly is taken apart.

This DBH 8109/85 seal is identified by its designation and by the dimensions shown on the product page: shaft (d) 24 mm, housing (D) 34.4 mm and height (h) 15.00/19.50 mm. The A 110 design corresponds to a radial shaft seal with a sealing lip and a metal case, designed for rotating shafts with permanent lubrication. The double height (15.00/19.50 mm) indicates that the profile allows variation in the seat, which is common in seals with a flange or an auxiliary lip. Before installing, check that the housing has no burrs or marks that could damage the lip.

Radial shaft seals of this size are used in gearboxes, electric motors, centrifugal pumps, compressors and transmission equipment. They also appear on fan, mixer and conveyor shafts, where there is continuous rotation and the presence of oil or grease. In food, chemical or water treatment plants, the seal also performs a containment function: it prevents leaks that affect the process and protects the neighboring bearings. If the equipment works with a lot of dirt or water, it is advisable to evaluate a seal with an additional lip or a dust guard.

To select a seal properly, measuring the shaft is not enough: you must check the housing diameter and depth, the condition of the shaft surface (hardness and roughness), the rotation speed and the type of lubricant. A scratched shaft or one with oval wear means the lip does not seat evenly and the leak reappears. During installation, lubricate the lip with the same oil used in the equipment, insert it perpendicular with a tube or press and avoid hitting it with a hammer. If the housing is damaged, consider resurfacing it or using a seal with an oversized case.
