The DBH 8820 oil seal is a radial shaft seal with a 156.20 mm shaft diameter, 185.40 mm housing diameter and 16.00 mm height, in design A 137. It is used to retain lubricant and exclude contaminants in rotating equipment, where the shaft turns inside a fixed housing. It is a common replacement part in pumps, gearboxes and motors, and its correct selection depends on the dimensions and the type of service.

This item is a radial shaft seal from the DBH line, identified by code 8820. Its dimensions are 156.20 mm shaft diameter, 185.40 mm housing diameter and 16.00 mm height. Design A 137 corresponds to a specific construction within the oil seal category. These values are what define interchangeability: if the shaft or the housing do not match, the seal will not seat or seal properly.

Seals of this size are found in industrial-scale transmission and pumping equipment. Typical applications: gearboxes, centrifugal pumps, large electric motors, conveyor rollers and continuous-process machinery. In every case, the function is twofold: keep the lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and gears.

To install a seal, check that the shaft has no burrs or deep marks, lubricate the lip before inserting it and seat it perpendicular to the shaft. Selection is defined by the three dimensions —shaft, housing and height— and by the service conditions: speed, temperature and type of fluid. If the seal works under pressure, vibration or heavy contamination, it is worth evaluating a design with reinforcement or a different material.

If you need an equivalent or a nearby size, the most practical approach is to send code 8820 and the current shaft and housing dimensions. With that data, an alternative in the same category or a combination that fits without modifying the machining can be found. You can also ask about seals from other brands or complete sets for a specific piece of equipment.
