The DBH 8186 radial shaft seal is a lip seal designed to stop oil or grease from passing through on rotating shafts and to prevent dust and contaminants from entering. Thanks to its dimensions of 45 mm shaft, 65 mm housing and 9 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this official brand and advises you on choosing the right seal for your application.

The DBH 8186 is a radial shaft seal with an Mx-Hel design, with a 45 mm shaft diameter, 65 mm housing diameter and 9.00 mm height. The sealing lip, the spring and the outer body are designed to retain lubricant and exclude particles in equipment with rotating motion. The designation 8186 identifies the exact size within the DBH line, and the suffix Mx-Hel indicates the lip and spring configuration. It is a wear part that should be replaced when lubricant leakage or dirt ingress appears.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all these cases it works on a rotating shaft and against a fixed housing, separating the oil from the environment. It is also used in machine tools, process equipment and conveying equipment, where sealing prevents leaks and protects the bearings. If the equipment operates with heavy vibration or temperature, it is advisable to check the condition of the shaft and housing before replacing it.

To install the DBH 8186, verify that the shaft is 45 mm and the housing is 65 mm, with a height of 9.00 mm. Check that the shaft has no burrs, deep scratches or wear in the lip contact area. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft, without striking the lip. If the housing is damaged, consider a sleeve or an alternative size. Correct alignment and a suitable shaft surface extend the life of the seal.
