The DBH 9290 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its size range—55 mm shaft, 68 mm housing, and 8.00/11.70 mm height—makes it a common fit for gearboxes, pumps, motors, and power transmission assemblies. MR Industrial Accessories supplies this brand and can help you match the right seal to your application.

This seal carries the code 9290 and the design designation A 179. The dimensions are shaft 55 mm, housing 68 mm, and overall height 8.00/11.70 mm. The two height values indicate an outer dust lip in addition to the primary sealing lip. Design A 179 uses a metal case with an elastomeric coating and a spring that maintains lip contact against the shaft.

Seals of this size are found in gear reducers, centrifugal pumps, electric motors, drive shafts, and continuous process lines. In each case the seal does two jobs: it holds oil or grease inside the assembly and blocks dust, water, and particles from entering. Because it is a wear component, inspect the sealing area whenever leaks or unusual noise appear.

Proper installation starts with a clean shaft free of burrs and marks, and a sealing surface with suitable hardness and roughness. Coat the lip with the same oil used in the equipment, then press the seal in perpendicular to the shaft without hitting it directly. If the housing has a shoulder, observe the required installation depth. When fluid compatibility, operating temperature, or peripheral speed is uncertain, check with us before installing.

For a replacement, the simplest path is to send code 9290 or the current dimensions—shaft, housing, and height. From that data we can identify alternatives within the same brand or other lines we carry. We can also confirm whether your original seal has a special feature, such as a double lip or dust lip, so the substitute matches as closely as possible.

MR Industrial Accessories stocks the DBH brand as one of the lines we supply. To request a quote or technical guidance, send code 9290 through WhatsApp and we will respond with the information your equipment needs.
