The DBH 9764 radial shaft seal is a lip seal designed to close off lubricant and block the entry of contaminants in equipment with a rotating shaft. Its dimensions of 114.3 mm shaft, 139.6 mm housing and 12.70 mm height place it in medium-to-large assemblies. It is a common replacement part in pumps, gear reducers and transmission cases operating with exposure to dust, water or chips.

This item is a radial shaft seal from the DBH brand, identified by the code 9764. Its dimensions are 114.3 mm shaft diameter, 139.6 mm housing diameter and 12.70 mm height. Design Kx corresponds to a lip configuration with spring that ensures constant contact on the shaft. The elastomer and the internal spring work together to maintain dynamic sealing in both directions of rotation.

Seals of this size are used in equipment where the shaft rotates continuously and there is a risk of oil leakage or particle ingress. They appear in centrifugal pumps, speed reducers, gearboxes, mixers and conveyors. They are also found in agricultural and industrial machinery operating outdoors, where the seal protects the bearings and extends the service life of the assembly.

To correctly select this seal, verify that the shaft and housing diameters match the indicated values. The 12.70 mm height must fit into the cavity without forcing. During installation, lubricate the lip with the same oil as the equipment, avoid striking it and make sure the spring is on the side of the fluid to be retained. A shaft with wear or deep scratches can compromise sealing.
