This item is a radial shaft seal from the DBH brand, identified by part number 6423. Its dimensions are 50.80 mm shaft diameter (d), 76.12 mm housing diameter (D) and 18.25 mm height (h). The Mx design corresponds to a particular construction geometry within the DBH line, combining a sealing lip and a reinforced body to withstand normal working conditions. It is a direct replacement part for equipment that requires these exact dimensions.

Typical applications for a seal such as the DBH 6423 include gearboxes, pumps, electric motors, reducers and rollers, where oil or grease must be contained and dust or water kept out. It is also used on drive shafts and continuous-process machinery. Its size and configuration make it suitable for equipment with shafts of approximately 50 mm diameter and housings machined to standard norms.

To install this seal correctly, check that the shaft and housing are clean, free of burrs and scratches, and that the shaft surface has the right hardness and roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it directly. If the equipment runs at high peripheral speed or elevated temperatures, consult MR to evaluate the lip material and the type of elastomer.
