The DBH 8641 radial shaft seal is a lip seal that mounts in a component's housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and stop dust, water or particles from entering. It is used in gearboxes, pumps, electric motors and power transmission equipment, where the shaft rotates continuously and a reliable barrier is needed. MR Accesorios Industriales carries this brand and advises you on choosing the right size.

This DBH 8641 oil seal has a shaft diameter of 34 mm, a housing diameter of 55 mm and a height of 11.00 mm. The Lx design indicates a single-lip configuration with a spring, suitable for rotating shafts with lubrication. The flexible lip rests on the shaft and the spring maintains contact pressure to compensate for wear. The outer case is metal and the elastomer resists industrial oils and greases. It is a standard replacement part, not a custom component.

Typical applications for this type of oil seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. It is also used in machine tools, food industry equipment and hydraulic systems where the lubricant must be separated from the environment. In all cases, the seal works on a rotating shaft and a fixed housing, and its service life depends on clean installation and the condition of the shaft surface.

To install the seal, check that the shaft has no burrs, scratches or wear in the contact area. Lubricate the lip with the same grease or oil used in the equipment before inserting it. Place the seal perpendicular to the shaft and use a tube or press that bears on the outer edge, never on the lip. If the housing has a shoulder, respect the installation depth. To select a replacement, take into account the shaft size, housing diameter, height and design type; if the shaft is worn, consider a seal with an auxiliary lip or a repair sleeve.
