The DBH 5256Sil radial shaft seal is a lip seal designed for rotating shafts of 25 mm diameter, with 35 mm housing and 7 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that accelerate wear of bearings and bushings. It is a common replacement part in gear reducer boxes, pumps, electric motors and transmission equipment operating in workshops, plants and agricultural machinery.

This DBH 5256Sil seal has a shaft diameter of 25 mm, a housing diameter of 35 mm and a total height of 7.00 mm. The Lz design corresponds to a configuration with sealing lip and spring, intended for rotating shafts with permanent lubrication. The designation 5256Sil identifies the exact size within the DBH line, and the SKU code DBH-5256SIL allows it to be located unambiguously in our catalog. It is a radial sealing component for general industrial use.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, speed reducers and belt or chain transmission equipment. It is also used in agricultural machinery, conveyors and hydraulic systems where there is a shaft rotating inside a fixed housing. In all cases, its purpose is to confine oil or grease and block the entry of external contaminants that reduce the service life of bearings.

For correct assembly, verify that the shaft has the 25 mm dimension and the housing the indicated 35 mm, without burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil as the equipment before inserting it, and place the seal perpendicular to the shaft, with a suitable tool that rests on the metal edge. The 7.00 mm height should sit flush or slightly recessed according to the housing design. If the shaft shows wear, consider a repair sleeve.
