This item is a radial shaft seal from the DBH brand, identified with part number 5642. Its standardized dimensions are 42.40 mm shaft diameter (d), 66.90 mm housing diameter (D) and 12.80 mm height (h). The Mx design indicates a configuration with a main sealing lip and a secondary exclusion lip, which improves protection against dust and dirt in demanding environments. The lip elastomer is designed to resist common industrial oils and greases.

Typical applications for this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. It is used to seal the shaft passage through the housing, preventing lubricant leaks and the entry of external particles. It is common in agricultural machinery, process equipment and continuous conveying systems where a reliable, low-maintenance barrier is required.

To install the seal correctly, verify that the shaft and housing diameters match the dimensions indicated. The shaft surface must be clean, free of burrs or marks, and lubricated before inserting the seal. It is important to align the seal perpendicular to the shaft and use a suitable installation tool so as not to damage the lip. Selection must consider rotation speed, operating temperature and the type of lubricant, factors that influence the service life of the seal.
