The DBH 9934 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 40 mm shaft in a 74 mm housing, with a height of 10.00/18.50 mm. The A 103 design combines a sealing lip with a metal case, and the stepped height indicates an auxiliary dust lip that sits outside the housing. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.
Key dimensions for the DBH 9934 are shaft 40 mm, housing 74 mm, and overall height 10.00/18.50 mm. The code 9934 identifies this size within the DBH line. The A 103 designation refers to a seal with a sealing lip and a metal outer body, intended for rotating shafts. The dual height figure means the seal has an additional lip that extends beyond the housing bore, adding a barrier against dust and other external contamination.
You will find this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and other power transmission equipment. In each case, it seals the point where the shaft passes through the housing, holding oil or grease in and keeping dirt out. That protection helps bearings and gears last longer and keeps the surrounding area clean.
For installation, check that the shaft measures 40 mm and the housing bore 74 mm, with no burrs and within tolerance. Apply compatible grease to the lip before pressing the seal in, and keep it perpendicular to the shaft. Confirm that the 10.00/18.50 mm height matches the housing depth and the space available. If the shaft shows wear, you may need to reposition the lip or use a wear sleeve.
