The DBH 9788 is a radial shaft seal that presses into the housing and runs against the shaft to keep lubricant in and contaminants out. It measures 26 mm at the shaft, 56 mm at the housing and 8 mm in height, and uses the Lx design. You will find it in gearboxes, pumps, motors and other power transmission equipment where sealing must be dependable and replacement straightforward.

This seal has a single lip, a metal case and the Lx design. The Lx designation means the lip is spring-loaded and the outside of the case is made to press-fit into the housing bore. Sizes are shaft 26.00 mm, housing 56.00 mm and height 8.00 mm. DBH is one of the brands MR supplies, so the code 9788 identifies the part clearly when you order.

Typical applications are any assembly where a shaft turns inside a lubricated housing: gearboxes, centrifugal pumps, electric motors, rollers and conveyors. It also shows up in agricultural and road machinery and in process lines where oil loss and incoming dirt must be controlled. Because it is a wear part, a hardened lip or a scored shaft will cause weeping, and the seal should be changed at that point.

When installing, check that the shaft is clean, free of burrs and has the correct surface roughness, and that the housing bore is free of dents and rust. Coat the lip with the same oil or grease used in the equipment, then seat the seal square to the shaft without twisting it. If the shaft has a deep groove, a seal with the lip in a different position may be needed. Speed, temperature and lubricant type all affect selection.

If you need a different size or an equivalent, send part number 9788 along with the shaft, housing and height dimensions, plus the fluid and operating temperature. With those details we can look for options in the same series or in other brands we carry.
