The DBH 9790 oil seal is a radial shaft seal with a 28.00 mm shaft diameter, 40.00 mm housing diameter and 8.00 mm height, in the Lx design.

It is a common wear part in pumps, electric motors, gearboxes and power transmission equipment, where correct sealing prevents oil loss and keeps dust or water out of the bearing.

This item is a DBH 9790 radial shaft seal, identified by its designation 9790. Its dimensions are 28.00 mm shaft diameter (d), 40.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a configuration with a sealing lip and metal body, suitable for press fitting into a housing. DBH is a brand MR sells, so the replacement is available under that exact reference.

Typical applications for a seal of this size include centrifugal pumps, electric motors, gearboxes, compressors and power transmission equipment. In all cases, the seal works against a rotating shaft and a fixed housing, retaining the oil or grease of the bearing and blocking the entry of dirt, chips or water. It is also used in industrial washing machines, mixers and conveyors.

When fitting a radial shaft seal, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Press the seal in with a suitable tool, applying force on the outer edge and without striking the lip. Before fitting it, lubricate the lip with the same oil or grease used in the equipment. If the shaft shows a deep groove, consider a repair sleeve.
