The DBH 8711 is a radial shaft seal from the DBH line, identified by code 8711. It is a single-lip seal with spring, Mx design, built to retain lubricant and block contaminants in rotating equipment. Its dimensions are 41.40 mm shaft, 70.60 mm housing and 7.90 mm height. MR Industrial Accessories supplies this brand for replacements that require the exact size.

This seal is commonly used in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. Its role is to keep grease or oil inside the assembly and keep dust, water and particles out, protecting bearings and gears from premature wear. As a wear part, it should be replaced when leaks appear or when the lip shows hardening, cuts or deformation.

To select the correct seal, confirm that the shaft diameter and housing diameter match the values above. The 7.90 mm height must fit the cavity without forcing, and the lip should be lubricated before installation. Avoid striking the seal during mounting; use a support tube that applies force on the metal ring, not on the elastomer. If the shaft has wear or grooves, consider a repair sleeve or an alternative size.

If you need an equivalent, send the code 8711 or the current dimensions of the assembly. We can look for alternatives within the same DBH brand or from other lines we carry, always respecting shaft, housing and height. We can also advise if the Mx design is not suitable and another lip type or material should be evaluated.
