The DBH 6443 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 54 mm shaft diameter, 76.12 mm housing diameter and 19.05 mm height make it suitable for equipment with standard housings. It is press-fitted into the housing and runs on the shaft with a lubricating film that ensures sealing and low friction. It is a key component for protecting bearings and extending the service life of gearboxes, pumps and motors.

The DBH 6443 is a seal with an Mx design, featuring a sealing lip and a metal case. Its dimensions are: shaft diameter (d) 54 mm, housing diameter (D) 76.12 mm and height (h) 19.05 mm. These dimensions correspond to the 6443 designation and allow replacement of worn seals in equipment using this standard size. The Mx design indicates a specific lip and spring configuration, suitable for applications with moderate peripheral speeds and the presence of oil or grease.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, drive shafts and power transmission equipment. In all cases, its function is to prevent lubricant leaks and the ingress of dust, water or particles that accelerate wear on bearings and gears. It is commonly found in industrial machinery, process equipment and vehicles, where sealing reliability is critical to avoid unplanned downtime.

To correctly select a seal, verify that the shaft and housing dimensions match those of the equipment. The height must be compatible with the housing depth. During installation, lubricate the lip with the same service oil or grease, insert the seal perpendicularly and apply uniform pressure on the outer ring. Avoid striking the lip or the spring. If the shaft shows wear or roughness, consider repair or use of a seal with an auxiliary lip.
