This item is a DBH brand radial shaft seal, identified by the code 5190. Its dimensions are: shaft diameter 50.80 mm, housing diameter 80.11 mm and height 9.52 mm. The A 011 design corresponds to a single-lip seal with spring, suitable for rotating lubricated shafts. The 5190 designation is the reference you will find on the manufacturer's product page and on the marking of the part. It is a sealing component that is mounted in the housing and seals against the moving shaft.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all these cases, the seal prevents oil or grease leakage and blocks the entry of dust, water or particles. It is also used in machine tools and industrial equipment where there are rotating shafts that require permanent lubrication. Its size makes it suitable for shafts with a diameter close to 50 mm, common in medium-power equipment.

To install this seal correctly, make sure the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The seal is press-fitted into the housing, with the lip facing the lubricant side. Make sure the shaft is not worn in the contact area and that runout is within tolerance. If the shaft shows a groove or wear, consider a repair sleeve or an alternative size.
