The DBH 9022 oil seal is a single-lip radial shaft seal with a spring, designed for rotating shafts where lubricant must be retained and dust, water or particles kept out. With its size of 90 mm shaft, 110 mm housing and 12 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment. At MR Accesorios Industriales we sell it as part of our line of seals and oil seals for maintenance and replacement.

The DBH 9022 is a radial shaft seal with an Lx design: elastomer lip with metal spring and outer case. Its dimensions are 90 mm shaft diameter (d), 110 mm housing diameter (D) and 12.00 mm height (h). The flexible lip runs on the rotating shaft and the spring maintains constant contact pressure, while the rigid case seats in the housing bore. It is a wear part: when the lip hardens or becomes marked, it starts to lose oil.

Typical applications for this size appear in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. It is also used in mixers, agitators and machine tools where the shaft rotates inside a fixed housing. In all cases it performs the same function: retaining lubricant on the inner side and preventing contaminants from the environment from entering, extending the life of bearings and gears.

To install a seal of this type, check that the shaft is clean, free of burrs or marks, and that the sliding surface has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it from the side. If the housing has burrs, pass a fine file. The 12 mm height allows you to replace seals of the same size without modifying the housing. If the shaft is worn, consider a seal with an offset lip or a wear sleeve.

If you need an equivalent, send us code 9022 or the full size 90x110x12 via WhatsApp. You can also send the original manufacturer's code or the dimensions measured with a caliper. At MR Accesorios Industriales we cross-reference the size with the lines we sell and confirm the exact size. If the seal is mounted on critical equipment, it is advisable to also check the condition of the shaft and housing before ordering the replacement.
