The DBH 5278 radial shaft seal is a lip seal that mounts on the shaft and inside the housing to retain lubricant and exclude contaminants. Its dimensions of 60 mm shaft diameter, 90 mm housing diameter and 10 mm height make it suitable for equipment with medium-section shafts. It is a wear part that should be replaced when leaks or noises appear, and MR Accesorios Industriales offers it as part of its seals line.

This item is a radial shaft seal from the DBH brand, identified with part number 5278. According to the product page data, it corresponds to a shaft of 60 mm diameter (d), a housing of 90 mm diameter (D) and a total height of 10 mm (h). The indicated design is Lx, which refers to a specific construction configuration within the oil seal category. It is an elastomeric lip seal with metal reinforcement, designed to operate in rotation and maintain sealing at the point where the shaft passes through the housing.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment with 60 mm shafts. In all cases it performs the dual function of retaining the oil or grease inside and preventing the entry of dust, water or particles. It is commonly found in assemblies where the shaft rotates continuously and a reliable barrier against leaks is required.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the available height. Rotation speed, working temperature and the type of lubricant also matter. The Lx design responds to a particular geometry that should be respected when replacing. During assembly, the lip must be lubricated and the seal must enter perpendicular to the shaft, without blows that deform the housing. If the shaft shows wear or burrs, the new seal may fail prematurely.

If you need a nearby size or an equivalent, the most practical approach is to send us part number 5278 along with the shaft, housing and height dimensions shown on the equipment. With that data we can look for alternatives within the same category or from other brands we carry. We can also advise you if the Lx design is not available and a compatible construction variant needs to be evaluated. The more complete the assembly information, the more accurate the proposal will be.
