The DBH 9185Pol radial shaft seal is a rotary shaft seal that prevents lubricant leakage and the ingress of contaminants in gearboxes, pumps and power transmission equipment. Its Lx-R-AH design combines a sealing lip with a reinforcement that gives it stability against pressure and misalignment. With a 68 mm shaft diameter, 84 mm housing diameter and 8.50 mm height, it is press-fitted into the housing and runs on the shaft with a controlled oil film. MR Accesorios Industriales sells it as part of its seals and radial shaft seals line.

This DBH 9185Pol radial shaft seal has a shaft diameter of 68 mm, a housing diameter of 84 mm and a height of 8.50 mm. The Lx-R-AH design corresponds to a seal with a sealing lip, a reinforced body and a configuration that improves stability against internal pressure. The 9185 series nomenclature identifies the size and the construction type; to confirm the exact lip geometry and the elastomer material, consult the manufacturer's data sheet. It is a replacement part for shafts rotating within a moderate range of peripheral speed.

It is used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment where a shaft passes through a housing and oil or grease needs to be retained. It also appears in applications exposed to dust, wash water or chips, provided the seal is protected by a cover or a labyrinth. In food plants, water treatment and mining, it is chosen for its ability to seal without requiring frequent maintenance. If the equipment operates with high vibration or misalignment, it is advisable to evaluate a design with greater rigidity or an auxiliary lip.

For installation, verify that the shaft diameter is within the recommended tolerance and that the sealing surface has no scratches or wear. The housing must be clean, free of burrs, and the seal is inserted with a suitable installation sleeve, never by striking the lip. Lubricate the lip with the same oil as the equipment before installing. Selection depends on shaft speed, operating temperature and the type of fluid; if these data are not defined, consult the manufacturer or MR to choose the correct compound.
