The DBH 6689Pol is a radial shaft seal with a sealing lip, built for rotating shafts. It measures 65 mm at the shaft, 90 mm at the housing and 13.00 mm in height, and its Mz-R design defines a specific lip and outer body configuration. This seal keeps oil or grease in and contaminants out in gearboxes, pumps, motors and similar equipment.

In service, the seal is pressed into the housing while its flexible lip runs against the shaft. That contact is what retains lubricant and blocks dust or water. The Mz-R designation points to a particular lip and body arrangement intended for dynamic sealing on rotating shafts.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission components. In each case the seal protects bearings and gears from lubricant loss and outside contamination. Agricultural machinery, process equipment and linear motion systems are common hosts for this type of seal.

Selection starts with matching the three dimensions: shaft 65 mm, housing 90 mm, height 13.00 mm. Check that the shaft is free of burrs, scratches or heavy wear, since surface finish affects lip life. During installation, coat the lip with the same oil or grease used in the application, press evenly on the outer diameter with a proper tool, and avoid hitting the lip or its spring. If the shaft shows a groove, a wear sleeve or a different size may be the better route.

If you need an equivalent, send us the original part number, the shaft and housing dimensions, and the lubricant type. We can source alternatives in other brands or similar configurations while keeping the critical dimensions your equipment requires. We can also advise on lip orientation and seal material based on your temperature and speed conditions.
