This item is a radial shaft seal from the DBH brand, identified by part number 6142. Its dimensions are 20.00 mm shaft diameter (d), 55.50 mm housing bore diameter (D) and 11.00 mm height (h). The A 079 design corresponds to a standard single-lip configuration with spring, suitable for retaining oil or grease on rotating shafts. Made with quality elastomers, it offers resistance to wear and temperature. It is a key part for maintaining the integrity of gearboxes, pumps and motors.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, transmission shafts and continuous process equipment. It is used in industries such as food, chemical, petrochemical and manufacturing, where lubricant containment and exclusion of dust or water are critical. Its compact size makes it suitable for tight spaces without sacrificing sealing capacity. It is commonly found in machinery operating at moderate speeds and low pressures.

For correct installation, verify that the shaft and housing diameters match the indicated dimensions. Lubricate the lip before inserting it and make sure the shaft has no burrs or grooves that could damage the seal. Selection must consider rotation speed, operating temperature and the type of fluid to be retained. If the seal is installed in a housing with an inadequate surface finish, it may fail prematurely. Always consult the tolerances recommended by the manufacturer for each application.
