The DBH 9864/85 radial shaft seal is a lip seal that is mounted in the housing and seals against the shaft to retain lubricant and stop the entry of dust, water or particles. 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 sells this brand and helps you confirm the correct variant.

This item is a radial shaft seal from the DBH line, identified with part number 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 the entry of contaminants is needed.

Typical applications for an oil 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 kept contained within the assembly. In all cases it works on a rotating shaft or with relative movement inside a fixed housing.

To mount it correctly, verify 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 proper entry chamfer. The lip must not be mounted dry: lubricate it with the same grease or oil used in the equipment. If the shaft shows wear, consider 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 thing is to send us part number 9864/85 along 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 within the DBH line. We can also guide you if the A 100 design is not the one that corresponds to your application and a different lip profile is needed.

MR Accesorios Industriales sells the DBH brand as part of its line of seals and oil seals. If you want to request a quote for the 9864/85, write to us on WhatsApp with the part number and dimensions.
