The DBH 8510Pol oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 42 mm shaft diameter, 62 mm housing diameter and 8 mm height, it is a common size in gearboxes, pumps and medium-sized electric motors. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This oil seal has a shaft diameter of 42 mm, a housing diameter of 62 mm and a height of 8.00 mm. Its Lx-H design corresponds to a sealing lip with spring and outer metal case, designed to be press-fitted into the housing with the lip resting on the shaft. The designation 8510Pol identifies the size within the DBH line. It is a direct replacement component when the size matches the machined housing.

It is used in equipment with continuous rotation where oil or grease must be contained: gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. It also appears in applications exposed to dust or water, where the lip must stop contaminants from entering the bearing. In those cases, it is advisable to check the hardness and surface finish of the shaft before replacing.

To select an oil seal correctly, verify that the shaft diameter is within the recommended tolerance for radial shaft seals and that the housing has no burrs or scratches in the seating area. The lip must be lubricated before mounting and the shaft must not show a worn track where the previous oil seal rested. If the shaft has a marked groove, it is sometimes advisable to slightly shift the oil seal position or use a wear sleeve.

With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the housing has been modified and the original size no longer matches.
