The DBH 8066Pol is a radial shaft lip seal built for rotating shafts. Reading the size code gives shaft 80 mm, housing 100 mm and height 12 mm. Its job on a gearbox, pump or similar machine is twofold: hold the lubricant inside and keep dust, water and grit out. The Mx-R configuration is a single lip with a spring, so the sealing edge stays in contact with the shaft through continuous rotation. Keeping that edge in good condition is what protects bearings and gears from leakage and early wear.

The three figures in the size code tell you where the seal sits: 80 mm is the shaft it rides on, 100 mm is the bore it presses into, and 12.00 mm is the width across the outside. The Mx-R designation describes the element itself, a spring-loaded single lip for rotating service. Within the DBH line, 8066Pol pins down that exact size and build. Measure both the shaft and the housing bore before you install anything, because a seal that is off by even a small amount will leak or fail early.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and other power transmission equipment. In each case it does the same two jobs: it stops oil or grease from escaping and it shields the bearings from dust, water and abrasive particles. Agricultural and industrial machinery that runs shafts at moderate to high speed also relies on this kind of sealing. The Mx-R lip works with either oil or grease lubrication.

Selection comes down to three measurements: shaft diameter, housing bore and width. Check the shaft first. Burrs, scratches or a worn track will keep the lip from sealing, no matter how good the seal is. Lubricate the lip with the same lubricant the equipment uses, fit it with a proper driver, and press it in square and flush with the housing. If the shaft already shows a groove, consider a wear sleeve or a different seal size.

If you are chasing an equivalent, send the code 8066Pol or the exact dimensions of your application. We handle seals and oil seals in many brands and configurations, and our team can help you match one to your working conditions: speed, temperature, lubricant type and contamination level. Special designs are also available for applications that need them.
