The DBH 9191Vit is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 90 mm shaft, a 110 mm housing bore and a 7 mm width, and it follows the A 156-R AH design. You will find it in gearboxes, pumps, electric motors and similar transmission assemblies. The elastomeric lip runs against the shaft while the outer circumference holds in the housing. MR supplies this brand and can help you confirm the size and compound for your application.

Reading the code helps you match the part quickly. The 9191Vit designation identifies the seal profile, while A 156-R AH describes the lip geometry and metal case. The three dimensions to check are shaft 90 mm, housing 110 mm and width 7.00 mm. The lip contacts the rotating shaft; the outside diameter presses into the housing bore. Together they block oil or grease from escaping and keep dust, water and particles from entering. Because it is a wear part, replace it whenever you see lubricant loss or heavy contamination around the shaft.

You will run into this seal in gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. It also appears in agricultural machinery, transport units and plant equipment where shafts turn under permanent lubrication. In every case, the seal separates the lubricated side from the outside and protects bearings and gears. If the equipment sees a lot of dirt or water, review the lip design and elastomer before you order a replacement.

Installation starts with the shaft. It should be free of splines and burrs and have the right surface roughness. The housing must be clean, undamaged and at the correct diameter. Lubricate the lip before you push the seal in, and use a tube or press that contacts only the outer edge, never the lip. A worn shaft may call for a repair sleeve. Speed, temperature and the fluid being sealed all affect selection, so ask if anything is unclear.

To quote a seal equivalent to the 9191Vit, send the code, the shaft, housing and width measurements, and a photo of the housing. With that information we can look for alternatives in the same series or in other brands we carry. We can also verify the A 156-R AH design and the lip compound. The more precise your data, the faster we can respond.
