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

This item is a radial shaft seal from the DBH line, identified by the code 8711. Its dimensions are 41.40 mm shaft diameter, 70.60 mm housing diameter and 7.90 mm height. The Mx design corresponds to a single-lip configuration with spring, intended for rotating shafts at moderate speeds and with grease or oil lubrication.

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

To correctly select this seal, verify that the shaft diameter and the housing diameter match the indicated values. The 7.90 mm height must fit into the cavity without forcing, and the lip must be lubricated before mounting. 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 seal, the most practical thing is to send us the code 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 carry, always respecting the shaft, housing and height dimensions. We can also advise you if the Mx design is not suitable for your application and it is worth evaluating another type of lip or material.
