The DBH 8113 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its standard dimensions —50.80 mm shaft, 65.05 mm housing and 9.00 mm height— make it suitable for assemblies where axial space is limited. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with oil or grease. MR Accesorios Industriales supplies this reference as part of its seals and oil seals line for industrial maintenance.

This item is an Lx design oil seal, with the dimensions shown in its designation: shaft diameter 50.80 mm, housing diameter 65.05 mm and height 9.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with permanent lubrication. The 8113 nomenclature identifies the dimensional combination within the DBH line. It is a direct replacement part, not a kit or an assembled set. To confirm the application, keep in mind that housing and shaft tolerances must follow standard practices for mounting radial shaft seals.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all cases, the seal retains lubricant from escaping and prevents the ingress of dust, water or particles. It is commonly found in equipment where the shaft rotates at moderate speeds and the service temperature does not exceed the limits of the elastomer. If the equipment operates with high vibration or misalignment, a design with greater rigidity or an auxiliary lip should be evaluated.

To correctly select this oil seal, verify that the shaft diameter and housing diameter match the indicated values. The 9.00 mm height must fit into the cavity without forcing, leaving the lip in uniform contact with the shaft. During installation, lubricate the lip with the same oil or grease used in the equipment and use a guide sleeve to avoid damaging the sealing edge. Shaft eccentricity and surface finish influence service life: a shaft with adequate roughness and no splines improves performance.
