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 block the ingress of dust, water or particles. With its size of 26 mm shaft, 56 mm housing and 8 mm height, in Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment that require reliable sealing and easy replacement.

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 unambiguously identified when ordering.

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

For installation, verify that the shaft is clean, free of burrs and has the proper 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 install the seal perpendicular to the shaft without twisting it. If the shaft shows a deep groove, consider a seal with the lip in a different position. Selection depends on speed, temperature and lubricant type.

If you need an equivalent or a different size, send us code 9788 along with the shaft, housing and height dimensions, and the fluid type and operating temperature. With that data we look for alternatives in the same series or in other brands we carry.
