This item is a DBH 9939 radial shaft seal with A 347 design. Its main dimensions are 24.5 mm shaft diameter (d), 32 mm housing diameter (D) and 4.00 mm height (h). The A 347 design corresponds to a single-lip configuration with spring, suitable for rotating shafts where a barrier against oils, greases and particles is required. The designation 9939 identifies the size and construction type within the DBH line.

Radial shaft seals such as the DBH 9939 are used in gearboxes, pumps, electric motors, transmission shafts and power transmission equipment in general. Their function is to keep lubricant inside the assembly and prevent the ingress of dust, water or chips. They are common in industrial applications where axial space is limited and reliable sealing is needed at moderate speeds.

To install this seal, verify that the shaft diameter is within the recommended tolerance and that the contact surface is free of burrs or scratches. The housing must have a suitable finish and a depth that allows housing the 4.00 mm height without deforming the lip. Lubricate the lip before installation and avoid hitting it during assembly. If the shaft shows wear, consider a repair sleeve or an alternative size.
