The DBH 5978 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 49.20 mm shaft diameter, 76.22 mm housing and 12.70 mm height make it suitable for equipment where axial space is limited. It is used in pumps, electric motors, gearboxes and transmissions that operate with oil or grease. MR Accesorios Industriales sells this brand and advises you to choose the correct seal according to your application.

This item is a radial shaft seal from the DBH brand, identified with the code 5978. Its dimensions are 49.20 mm shaft diameter (d), 76.22 mm housing diameter (D) and 12.70 mm height (h). The Lx design corresponds to a seal with sealing lip and spring, without external dust lip. The sealing lip is designed to work on the rotating shaft, while the outer diameter maintains a static fit in the housing. The 12.70 mm height allows installing it in tight spaces without losing sealing capacity.

Typical applications of this seal include centrifugal pumps, electric motors, gearboxes, reducers and belt or chain transmissions. It is also used in process equipment, industrial washing machines and agricultural machinery where containing oil or grease and preventing the entry of dust or water is required. Its radial design is suitable for shafts rotating at moderate and high speeds, provided the shaft surface is ground and lubrication is correct.

To mount this seal, verify that the shaft diameter is within the recommended tolerance and that the sealing surface has no scratches or wear. The housing must have an entry chamfer to avoid damaging the lip during installation. Lubricate the lip with the same oil or grease as the equipment before inserting it. If the seal replaces a worn one, also check the condition of the shaft and housing, since a damaged surface shortens the service life of the new seal.
