The DBH 9290 oil seal is a single-lip radial shaft seal mounted on rotating shafts to retain lubricant and block the entry of dust, water or particles. Due to its dimensions —55 mm shaft, 68 mm housing and a height of 8.00/11.70 mm— 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 oil seal for your application.

This item is a DBH 9290 radial shaft seal, identified by code 9290 and design A 179. Its nominal dimensions are 55 mm shaft diameter (d), 68 mm housing diameter (D) and an overall height of 8.00/11.70 mm (h). That double height indicates that the oil seal has an outer dust lip in addition to the main sealing lip. Design A 179 corresponds to a metal case with elastomeric coating and a spring that keeps the lip against the shaft.

Typical applications for an oil seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, drive shafts and continuous process equipment. In all these cases the oil seal performs two functions: retaining the oil or grease inside the assembly and preventing contaminants from entering from the outside. It is a wear part, so it should be inspected when leaks or noise appear in the sealing area.

For correct installation, check that the shaft is clean, free of burrs and marks, and that the sealing surface has the appropriate hardness and roughness. Lubricate the lip with the same oil used in the equipment before inserting it, and place the oil seal perpendicular to the shaft, without striking it directly. If the housing has a shoulder, respect the installation depth. If you have doubts about material compatibility with the fluid, working temperature or peripheral speed, consult us before installing.

If you need an equivalent, the most practical approach is to send us code 9290 or the current dimensions (shaft diameter, housing diameter and height). With that data we can look for alternatives within the same brand or other lines we carry. We can also advise you if the original oil seal has a special design, such as a double lip or dust lip, so that the replacement is as close as possible.
