The DBH 9820/85 oil seal is a single-lip radial shaft seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and advises you on choosing the correct size.

This DBH 9820/85 oil seal has a shaft diameter of 17 mm, a housing diameter of 28.5 mm and a height of 7.00 mm. The Lr design corresponds to a spring-loaded sealing lip, intended for rotating shafts with lubrication. The 9820/85 nomenclature identifies the size within the DBH line. It is a direct replacement component when the original oil seal loses its elasticity or is damaged during disassembly.

Typical applications for this type of radial shaft seal are gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. It is also found in belt or chain drive equipment where oil or grease must be contained. In all cases it works against a rotating shaft and a fixed housing, with the sealing surface lubricated to prevent premature wear.

To install it, check that the shaft is clean, free of burrs or marks, and that the sealing surface has the appropriate roughness. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The oil seal must enter perpendicular to the housing, without blows that deform the lip. If the shaft shows wear, consider a repair sleeve or an oil seal with an offset lip. Selection depends on speed, temperature and the fluid to be retained.
