The DBH 9959Pol oil seal is a lip-type radial shaft seal designed to retain lubricant and block the entry of dust, water or particles into rotating equipment. It mounts on a 24 mm shaft and fits into a 35.15 mm bore, with a height of 7.70/10.00 mm that combines the fitting body and the sealing lip. It is a wear part: when oil leakage appears, the lip hardens or the shaft shows marks, it should be replaced. MR Accesorios Industriales supplies it as an official brand.

This item is a radial shaft seal from the DBH line, identified by part number 9959Pol. Its dimensions are shaft (d) 24 mm, housing (D) 35.15 mm and height (h) 7.70/10.00 mm. The A 160-R H design corresponds to a seal with a sealing lip and a reinforced body for the housing. The double height indicates that the seal has a fitting section and a flexible lip section: this allows it to absorb small misalignments and maintain contact on the rotating shaft. It is made of elastomer with an internal spring, suitable for continuous service with industrial oils and greases.

It is used in gearboxes, electric motors, centrifugal pumps, drive shafts and process equipment where the lubricant must be separated from the environment. It also appears in machine tools, conveyors and low-pressure hydraulic systems. In all these cases it performs two functions: preventing oil from escaping past the shaft and preventing contaminants from entering and wearing down bearings and gears. It is an inexpensive part within the assembly, but its failure can be costly if it leaves a bearing without lubrication.

To select it, verify that the shaft diameter is within tolerance and free of burrs or deep marks: the lip will not seal on a scratched surface. The housing must be clean, free of impacts, and with the entry chamfer in good condition so as not to cut the lip during installation. Lubricate the seal before fitting it and use a tube or support bushing to push it in evenly, never striking the lip. If the equipment operates with high vibration or temperature, contact us and we will evaluate an alternative compound or design.

If the part number 9959Pol does not appear on your list or you need a nearby size, send us the shaft, housing and height dimensions, plus a photo of the old seal and the seat. With that data we look for the equivalent in DBH or in another line we supply. We can also check whether a seal with a different height or an auxiliary lip is better suited. The more complete the information, the faster we reach the correct part.
