The DBH 5641 radial shaft seal is a lip seal that mounts on a 50 mm shaft and a 66 mm housing, with a height of 10 mm. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles, protecting bearings and bushings in rotating equipment. It is a wear part that should be replaced when oil leakage or shaft play appears.

This item is a radial shaft seal from the DBH line, identified with part number 5641. Its dimensions are 50.00 mm shaft diameter, 66.00 mm housing diameter and 10.00 mm height. The Mz design corresponds to a configuration with a sealing lip and metal reinforcement, suitable for rotating shafts with lubrication. It is made of elastomer resistant to oils and greases, with a case that gives it rigidity for press fitting.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where a shaft passage must be sealed. It also appears in agricultural machinery, conveyors and power transmission systems. It is common in applications where the shaft rotates at moderate speeds and the temperature does not exceed the limits of the elastomer. If the equipment works with a lot of vibration or misalignment, it is advisable to check the condition of the shaft before installing the new seal.

To select correctly, keep in mind that the shaft diameter, housing diameter and height must match those of the original seal. The Mz design defines the lip type and material, so if the environment has a lot of dust or water, a variant with a dust lip may be preferable. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid striking it. A scratched or burred shaft ruins the seal even if the seal is new.

To quote 5641, send us the data of the old seal: shaft diameter, outer diameter and height. With those three dimensions we can look for an equivalent in the same DBH line or in another brand we carry. We can also advise you if the Mz design is not suitable for your application and a different lip type or material is needed.
