The DBH 8098Pol oil seal is a radial shaft seal in Lz-R design that is fitted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its nominal dimensions are 85.70 mm shaft diameter, 100.00 mm housing diameter and 5.30 mm height. It is used in gearboxes, pumps, electric motors and power transmission equipment that operate with shafts of that diameter.

This item is a DBH radial shaft seal identified as 8098Pol. Its commercial designation corresponds to the 8098 series and the Pol variant. The dimensions shown on the product page are: shaft diameter (d) 85.70 mm, housing diameter (D) 100.00 mm and height (h) 5.30 mm. The Lz-R design corresponds to a sealing lip with spring and a body geometry that seats in the housing. It is a replacement part for equipment that already has that cavity defined.

Typical applications for an oil seal of this size include gearboxes, conveyor rollers, centrifugal pumps, medium-sized electric motors and belt or chain drive equipment. In all cases it fulfills the function of confining the oil or grease inside the assembly and preventing contaminants from entering from the outside. It is also used as a secondary barrier in bearing assemblies, where it protects the raceway and extends lubricant service life.

To install a radial shaft seal, it is advisable to check that the shaft has no burrs or deep marks in the contact area, and that the housing is clean and free of deformation. The lip is lubricated before inserting it and is seated with a flat tool to avoid damaging it. Selection is made by the three dimensions: shaft diameter, housing diameter and height. If the Lz-R design is not available, an equivalent with the same dimensions and lip type can be evaluated.
