The DBH 9217 radial shaft seal is a lip seal designed for rotating shafts of 25 mm diameter, with a 47 mm housing and 7 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings and gears. It is a wear part that should be replaced at every teardown or at the slightest sign of leakage. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a seal of A 101 design, with the following dimensions: shaft diameter 25 mm, housing diameter 47 mm and height 7.00 mm. The A 101 design corresponds to a single-lip seal with spring, suitable for rotating shafts with lubrication. The 9217 nomenclature identifies the dimensional combination within the DBH line. Before mounting, verify that the dimensions match the housing and shaft of your equipment, since even a minimal difference prevents correct sealing.

Typical applications of a 25x47x7 mm oil seal include gearboxes, electric motors, centrifugal pumps, reducers and power transmission equipment. It is also used in machine tools, conveyors and process equipment where there is a shaft rotating inside a housing and it is necessary to separate the oil from the environment. In all cases, the seal works together with a bearing or bushing, and its failure usually shows up as a lubricant leak or as ingress of contamination.

To correctly select this seal, take into account the shaft speed, operating temperature and type of lubricant. The A 101 design with spring is suitable for general applications, but if the equipment works with a lot of dirt or water, a seal with an auxiliary lip or dust guard may be preferable. During mounting, lubricate the lip with the same grease or oil as the equipment, insert it perpendicular to the shaft with a support tube and avoid striking it. A damaged or crookedly mounted lip causes premature leaks.
