The DBH 8711 radial shaft seal is a lip seal designed to block the passage of lubricant and prevent the entry of contaminants in rotating equipment. With dimensions of 41.40 mm shaft, 70.60 mm housing bore and 7.90 mm height, and an Mx design, it suits assemblies where axial space is limited. MR Accesorios Industriales supplies this official brand so you can handle replacements with the exact size.

This item is a radial shaft seal from the DBH line, identified by the part number 8711. Its dimensions are 41.40 mm shaft diameter, 70.60 mm housing bore diameter and 7.90 mm height. The Mx design corresponds to a single-lip configuration with a spring, intended for rotating shafts at moderate speeds with grease or oil lubrication. The lip elastomer and the metal of the reinforcement are not specified in the record, so they are confirmed against the manufacturer's data sheet at the time of inquiry.

Typical applications of a radial shaft seal of these dimensions include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases it serves to retain lubricant inside the assembly and block dust, water or particles that could accelerate wear of bearings and gears. It is a wear part that should be replaced when oil leakage appears or when the lip shows hardening, cuts or deformation.

To select this radial shaft seal correctly, check that the shaft diameter and the housing bore diameter match the values indicated. The 7.90 mm height must fit into the cavity without forcing, and the lip must be lubricated before fitting. During installation, avoid striking the seal and use a support tube that transmits force onto the metal ring, not onto the elastomer. If the shaft shows wear or grooves, consider a repair sleeve or an alternative size.

If you need an equivalent radial shaft seal or a nearby size, the most practical approach is to send us the part number 8711 or the current dimensions of the assembly. With that data we can look for alternatives within the same DBH brand or from other lines we supply, always respecting the shaft, housing bore and height dimensions. We can also advise you if the Mx design is not suitable for your application and another lip type or material should be considered.
