The DBH 8666Pol is a single-lip radial shaft seal sized for a 42 mm shaft, a 60 mm housing bore, and a 7 mm width. It is designed to retain oil or grease in rotating equipment while blocking dust, water, and other particles from reaching bearings and gears. The Lx-R-H designation describes the lip and body configuration. This seal is part of the seals and oil seals line we supply to maintenance and purchasing teams across the United States and Latin America.

The code 8666Pol identifies a specific size: shaft 42 mm, housing 60 mm, width 7.00 mm. The Lx-R-H design indicates the lip profile and seal body. Its compact cross-section suits housings with limited axial space. Always confirm these three dimensions against the shaft and bore before installation, because the nominal size in the designation is what determines fit.

Seals in this size range appear in gearboxes, centrifugal pumps, electric motors, reducers, and machine tools. They serve as a primary or secondary barrier, keeping lubricant where it belongs and keeping splashes or airborne dust out. The right lip material and elastomer depend on the fluid being sealed, the operating temperature, and the shaft speed.

For proper selection, check that the shaft diameter falls within the recommended tolerance and that the housing bore is free of burrs or wear. Lubricate the lip before mounting, and use an installation tool that presses on the outer edge, never on the lip itself. If the shaft shows a worn track, consider a seal with an offset lip. Confirm peripheral speed and working temperature with the manufacturer.

If you need an equivalent, send the code 8666Pol along with the shaft, housing, and width dimensions. A photo of the old seal or the housing drawing also helps. With that information, we can review alternatives within the DBH line and other brands we carry.
