The DBH 6689Pol radial shaft seal is a lip seal designed for rotating shafts. With dimensions of 65 mm shaft diameter, 90 mm housing diameter and 13 mm height, and an Mz-R design, it provides reliable sealing against lubricant leaks and the entry of contaminants. It is used in gearboxes, pumps, electric motors and industrial equipment where oil or grease must be retained under continuous rotation conditions. MR Accesorios Industriales carries this official brand for the Argentine market.

The DBH 6689Pol is a radial-type seal with a sealing lip. Its standard dimensions are 65 mm for the shaft diameter (d), 90 mm for the housing diameter (D) and 13.00 mm total height (h). The Mz-R design indicates a specific configuration of the lip and outer body, intended for applications with rotating shafts. This seal is press-fitted into the housing and its flexible lip contacts the shaft to prevent lubricant from passing outward and dust or water from passing inward.

Typical applications include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal protects bearings and gears from lubricant loss and external contamination. It is commonly found in agricultural machinery, process equipment and linear motion systems where reliable dynamic sealing is required.

To correctly select a seal, check that the shaft and housing dimensions match those of the seal. The shaft surface must be free of burrs, scratches or excessive wear; a suitable surface finish extends the life of the lip. During installation, lubricate the lip with the same oil or grease used in the application and use an installation tool that applies uniform pressure on the outer diameter. Avoid striking the lip or the spring. If the shaft shows a groove or wear, consider using a wear sleeve or an alternative size.
