The DBH 9864/85 radial shaft seal is a lip seal that is mounted in the housing and closes on the shaft to retain lubricant and stop dust, water or particles from entering. It is used in gearboxes, pumps, electric motors and transmission equipment where a shaft rotates inside a housing. Its dimensions are 18 mm shaft, 34 mm housing and 7 mm height, with A 100 design. MR Accesorios Industriales supplies this official brand and helps you confirm the correct variant.

This item is a radial shaft seal from the DBH line, identified by the code 9864/85. Its nominal dimensions are 18 mm shaft diameter, 34 mm housing diameter and 7.00 mm total height. The A 100 design corresponds to the construction geometry of the lip and the metal body according to the manufacturer's designation. It is a compact-section seal, intended for reduced radial spaces where an effective barrier against oil or grease leakage and contaminant ingress is needed.

Typical applications for a seal of this size include small gearboxes, centrifugal and positive displacement pumps, low-power electric motors, compressors, machine tools and belt or chain transmission equipment. It also appears on fan, mixer and conveyor shafts where the lubricant must be contained within the assembly. In all cases it runs on a rotating shaft or one with relative movement inside a fixed housing.

To install it properly, check that the shaft and housing diameters match the values on the product page, that the shaft surface is ground and free of burrs, and that the housing has the appropriate entry chamfer. The lip must not be installed dry: lubricate it with the same grease or oil used in the equipment. If the shaft shows wear, consider a nearby size or a seal with a taller lip. The selection depends on speed, temperature and the type of fluid to be retained.

If you need an equivalent or a different size, the most practical approach is to send us the code 9864/85 together with the shaft, housing and height dimensions, plus a photo of the old seal if you have it on hand. With that data we can look for the variant from the same brand or a compatible alternative within the DBH line. We can also advise you if the A 100 design is not the one for your application and a different lip profile is needed.
