The DBH 8654 is a radial shaft seal built for a rotating shaft of 31 mm, a housing bore of 48 mm and a height of 10 mm. Its job is to keep lubricant where it belongs and to stop dust, water and particles from reaching bearings and bushings. It sits press-fitted in the housing while its lip runs against the shaft, so the finish and condition of both surfaces largely determine how long it lasts. This is a standard maintenance replacement item.

The part belongs to the DBH seal line and carries the number 8654. In the size callout, the shaft measures 31 mm, the housing bore 48 mm and the overall height 10 mm. The Lx-R-AH designation describes the build: a sealing lip, a reinforced body and an outer geometry made for an interference fit in the housing. Sealing action happens where the lip contacts the shaft, while the outer diameter holds the seal in place. Always confirm these three dimensions against the real shaft and housing before fitting, since a different height or diameter will not seat or seal as intended.

You will find seals of this type in gearboxes, pumps, electric motors, conveyor rollers, drive shafts and process equipment. They are also common on agricultural and road machinery, and in any assembly where a shaft turns and lubricant must stay in while contamination stays out. Where dust, water or regular washdowns are present, the seal is the first line of defense, and its condition directly affects the bearing or bushing behind it.

Choosing the right seal takes more than the shaft size. The housing bore diameter and depth, the lubricant used, the rotation speed and the operating temperature all matter. The Lx-R-AH configuration of this part number is tied to a specific application. If the shaft shows wear, a repair sleeve or a spring-loaded lip may be worth considering. When installing, coat the lip with lubricant, avoid hitting it, and press it in square to the housing.
