The DBH 9788 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and slow the entry of dust, water or particles. Due to its size of 26 mm shaft, 56 mm housing and 8 mm height, with Lx design, it is used in gearboxes, pumps, electric motors and transmission equipment that need a reliable seal that is easy to replace.

The 9788 is a single-lip seal with metal case and Lx design. Its dimensions are 26.00 mm shaft diameter, 56.00 mm housing diameter and 8.00 mm height. The Lx design indicates a sealing lip with spring and a body that press-fits into the housing. DBH is a brand that MR carries, so the code 9788 is identified without ambiguity when ordering.

It is used in equipment where a shaft rotates inside a housing with lubricant: gearboxes, centrifugal pumps, electric motors, rollers and conveyors. It also appears in agricultural and road machinery and in process lines where oil leaks and the entry of contaminants must be prevented. It is a wear part: when the lip hardens or the shaft is marked, it starts to leak and should be replaced.

For installation, verify that the shaft is clean, free of burrs and with the appropriate roughness, and that the housing has no dents or rust. Lubricate the lip with the same grease or oil as the equipment before inserting it, and place the seal perpendicular to the shaft, without twisting it. If the shaft shows a deep groove, evaluate a nearby size or a seal with the lip in another position. The selection depends on speed, temperature and the type of lubricant.

If you need an equivalent or a different size, send us the code 9788 along with the shaft, housing and height dimensions, and the type of fluid and working temperature. With that data we look for alternatives in the same series or in other brands we carry. We can also check whether there is a nearby size that fits without modifying the housing.
