The DBH 5329 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil or grease in crankcases, gearboxes and pumps. Its Lz design combines a sealing lip with a dust lip that protects the contact area against external dust and dirt. With dimensions of 25.40 mm shaft, 50.80 mm housing and 10.00 mm height, it is a common replacement part in transmission equipment and industrial machinery.

This item is an oil seal from the DBH line, identified with part number 5329. Its nominal dimensions are 25.40 mm shaft diameter, 50.80 mm housing diameter and 10.00 mm height. The Lz design indicates that the seal has a main sealing lip and a secondary exclusion lip, intended for environments with dust or particles. The elastomer and the internal spring are not detailed in the record, so they are confirmed against the manufacturer's data sheet at the time of quoting.

Typical applications for a seal of this size include gearboxes, electric motors, centrifugal pumps, transmission shafts and continuous process equipment. It is generally found in assemblies where the shaft rotates at medium speeds and lubrication is by oil or grease. The dust lip of the Lz design is useful in areas with environmental dust, such as milling, mixing or material handling plants.

To mount a radial shaft seal, verify that the shaft diameter is within the recommended tolerance and that the contact surface has no burrs or deep marks. The housing must be clean and free of deformation. The 10.00 mm height defines the available axial space. During mounting, lubricate the lip and use a support tube so as not to damage it. If the shaft shows wear, consider a nearby size or a seal with an offset lip.
