This item is a DBH 8442 radial shaft seal, identified by its designation 8442. Its dimensions are 75 mm shaft diameter (d), 100 mm housing diameter (D) and 12.00 mm height (h). The Kx design corresponds to a configuration with a sealing lip and metal reinforcement, suitable for rotating shafts. The lip elastomer and the metal body work together to keep lubricant in and contaminants out. It is a wear part that is replaced during scheduled maintenance.

Typical applications for an oil seal of these dimensions include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, the oil seal is mounted in the cover or housing and seals against the rotating shaft. It is also used in rollers, mixers and process machinery where oil or grease leaks and the ingress of dust or water must be prevented. The choice of lip material depends on the fluid and the operating temperature.

To install a radial shaft seal, check that the shaft has no burrs or wear and that the sealing surface is clean. Lubricate the lip before inserting it and place the oil seal perpendicular to the shaft, without striking it directly. If the housing has a chamfer, this makes insertion easier. When selecting, take into account the shaft speed, temperature and type of lubricant. The Kx design and the 75x100x12 mm dimensions must match the housing and the shaft to prevent leaks.
