This item is a DBH radial shaft seal with the designation 9191Vit, with 90 mm shaft diameter, 110 mm housing diameter and 7.00 mm height. The A 156-R AH design defines the geometry of the lip and the metal body. The lip seals against the rotating shaft and the outer circumference is press-fitted into the housing. This prevents oil or grease leaks and the entry of dust, water or particles. It is a wear part: it is replaced when lubricant loss appears or the environment becomes contaminated.

Typical applications include gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. It is also used in agricultural machinery, transport and industrial plants where there are rotating shafts with permanent lubrication. In all cases, the seal separates the lubricated interior from the external environment and protects the bearings and gears. If the equipment works with a lot of dirt or water, it is advisable to check the lip design and the elastomer material before replacing.

To install a seal, check the condition of the shaft: no splines, no burrs and with the appropriate roughness. The housing must be clean, free of impacts and with the correct diameter. Lubricate the lip before inserting it and use a tube or press that rests on the outer edge, never on the lip. If the shaft is worn, consider a repair sleeve. Selection depends on speed, temperature and fluid; ask us if you have any doubts.
