The DBH 5489Sil radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 49.20 mm shaft, 63.55 mm housing and 7.14 mm height place it in equipment with medium-section shafts. It is used in gearboxes, pumps, electric motors and transmissions where the lubricant must stay inside and contamination outside.

This item is a seal from the DBH line, identified with the part number 5489Sil. Its dimensions are 49.20 mm shaft diameter, 63.55 mm housing diameter and 7.14 mm height. The Lx design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip runs on the shaft and the outer metal case is press-fitted into the housing. It is a wear part: over time the lip hardens or scores and starts to leak.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment. In all those cases it performs the same function: confining the oil or grease inside the assembly and preventing external agents from entering. It is also found in agricultural machinery, material handling equipment and production lines where shafts rotate with lubricated bearings.

For installation, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip before inserting it and do it with a flat driver so as not to deform it. Selection involves respecting the three seal dimensions and the design type: if the shaft has play or the speed is high, it is advisable to evaluate a configuration with an additional lip or a different material. Temperature and the working fluid also determine the appropriate elastomer.
