The DBH 6304 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —30.10 mm shaft, 43.55 mm housing and 15.87 mm height— make it suitable for installations where axial space is limited. It is manufactured with elastomer resistant to oils and greases, and is used in pumps, electric motors, gearboxes and transmission equipment. MR Accesorios Industriales sells it as part of its line of seals and oil seals.

The DBH 6304 is an oil seal with Mx design, featuring a sealing lip that runs on the shaft and an outer case that is press-fitted. Its standardized dimensions —shaft diameter 30.10 mm, housing diameter 43.55 mm and height 15.87 mm— allow replacement of worn seals in equipment with specific metric dimensions. The lip elastomer is formulated to resist mineral oils, greases and water, maintaining sealing under continuous rotation conditions.

This oil seal is used in applications where lubricant leaks and the ingress of dust or moisture must be prevented: centrifugal pumps, electric motors, speed reducers, transmission shafts and machine tools. It is also common in agricultural and industrial equipment operating with nominal 30 mm shafts. Its radial design allows installation in cylindrical housings without the need for auxiliary seals, provided the shaft surface is ground and free of burrs.

To correctly select an oil seal, verify the shaft size, housing diameter and available height. The lip must rest on a track free of wear or grooves; if the shaft shows marks, it is advisable to consider a wear sleeve or replace the shaft. Peripheral speed and working temperature determine the type of elastomer. During installation, lubricate the lip with the same oil as the equipment and place the seal perpendicular to the shaft, without striking the lip.
