The DBH 8654 radial shaft seal is a lip seal designed for rotating shafts with a 31 mm diameter, a 48 mm housing bore and a 10 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, so the quality of both surfaces defines its service life. It is a common replacement part in industrial maintenance.

This item is a seal from the DBH line, identified by part number 8654. Its dimensions are 31 mm shaft, 48 mm housing bore and 10 mm height. The Lx-R-AH design indicates a configuration with a sealing lip, a reinforced body and a geometry intended for interference-fit housings. The lip runs on the shaft and the outer diameter is fixed in the housing; that combination defines the sealing performance. Before mounting, check that the dimensions match the actual housing and shaft, because a seal with a different height or diameter will not seal correctly.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, conveyor rollers, drive shafts and process equipment. They also appear in agricultural and road machinery, and in any assembly with a rotating shaft that must keep lubricant in and contamination out. In environments with dust, water or frequent washdowns, the seal is the first barrier and its condition determines the life of the bearing or bushing it protects.

To select a seal correctly, the shaft diameter alone is not enough: the housing bore diameter and depth, the type of lubricant, the rotation speed and the operating temperature must all be respected. The Lx-R-AH design of this part number responds to a specific application; if the shaft is worn, it is worth evaluating a repair sleeve or a spring-loaded lip. During installation, lubricate the lip, avoid striking it and make sure it enters perpendicular to the housing.
