The DBH 6904 seal is a single-lip radial seal, designed for rotating shafts where lubricant must be contained and the ingress of dust, water or particles stopped. Due to its compact size and Ms design, it is used in gearboxes, pumps, electric motors and transmission equipment operating at moderate speeds. MR Accesorios Industriales supplies this official brand and helps you confirm that the size and compound are correct for your application.

This item is a DBH 6904 radial shaft seal. Its dimensions are 50.77 mm shaft diameter, 66.60 mm housing bore diameter and 6.35 mm height. The Ms design indicates a single sealing lip with spring, with an outer metal case. That combination of dimensions and design makes it suitable for housings where the seal is press-fitted and the shaft rotates within it. The 6904 designation identifies the part within the DBH line.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all these cases it performs the same function: retain oil or grease inside the assembly and prevent contaminants from entering from outside. It is also found in machine tools and continuous process equipment, where shaft sealing is critical for bearing service life.

For proper installation, verify that the shaft and housing diameters match the values on the product page. The shaft must be clean, free of burrs or marks, and it is advisable to lubricate the lip before inserting it. The seal is installed with the lip facing the fluid to be retained. If the shaft shows wear, consider a nearby size or a seal with the lip in another position. Compound selection depends on temperature and the working fluid.
