The DBH 1126 radial shaft seal is a lip seal that mounts in cylindrical housings to retain lubricant and block the entry of dust, water or particles in equipment with a rotating shaft. Its A 109 design and dimensions of 48.90 mm shaft, 63.00 mm housing and 10.80 mm height place it in continuous-duty industrial applications such as pumps, electric motors, gearboxes and conveyor rollers. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal for your equipment.

The DBH 1126 is a radial shaft seal with designation 1126 and A 109 design. Its dimensions are 48.90 mm shaft diameter (d), 63.00 mm housing diameter (D) and 10.80 mm height (h). The sealing lip runs on the rotating shaft and the outer diameter fits into the housing by interference, which ensures sealing in both directions. The A 109 nomenclature identifies the geometry of the lip and the metal body, a detail worth verifying against the manufacturer's data sheet before replacing an existing part.

This seal is used in equipment where a shaft rotates inside a lubricated housing: centrifugal pumps, electric motors, gear reducers, gearboxes, conveyor belt rollers and machine tools. It also appears in applications exposed to dust or water, where the seal prevents lubricant contamination and oil loss. If the equipment operates with vibration or misalignment, it is advisable to check the condition of the shaft and housing before installing the new seal.

To select a radial shaft seal, take into account the shaft diameter, housing diameter, height, type of lubricant, operating temperature and peripheral shaft speed. The A 109 design of the DBH 1126 corresponds to a standard single-lip geometry with spring. During installation, lubricate the lip with the same oil or grease used in the equipment, check that the shaft has no burrs or marks, and fit the seal perpendicular to the shaft without striking the lip. If the housing is damaged, consider a repair sleeve or an alternative size.
