The DBH 8098Pol is a radial shaft seal featuring an Lz-R design, which includes a spring-loaded lip and a body shaped to seat in a housing. It serves to keep lubricant in and contaminants out where a rotating shaft meets a fixed housing. The nominal dimensions are 85.70 mm for the shaft, 100.00 mm for the housing, and 5.30 mm for the height.

This seal belongs to the DBH 8098 series, with the Pol variant indicated in the part number. The size is defined by three values: shaft diameter (d) 85.70 mm, housing diameter (D) 100.00 mm, and height (h) 5.30 mm. The Lz-R construction combines a sealing lip with a spring and a body geometry that fits into the housing cavity. It is intended as a replacement for equipment that already has that cavity dimensioned.

Seals of this size are commonly found in gearboxes, conveyor rollers, centrifugal pumps, medium-sized electric motors, and belt or chain drive systems. Their role is to contain oil or grease within the assembly and to block dust, water, or particles from entering. They also act as a secondary barrier in bearing arrangements, helping to protect the raceway and maintain lubricant condition.

Proper installation starts with checking the shaft for burrs or deep marks in the contact area and ensuring the housing is clean and undistorted. Lubricate the lip before insertion and press the seal in squarely with a flat tool to avoid damage. Selection depends on the three dimensions—shaft, housing, and height—and an equivalent with the same dimensions and lip type can be considered.

If you need a replacement for the 8098Pol, provide the full part number, the shaft, housing, and height dimensions, and a photo of the old part if available. With that information, we can review alternatives within the DBH line or from other brands we supply. We can also help you choose the appropriate lip design based on the lubricant and operating conditions.
