The DBH 8427 radial shaft seal is a lip seal that mounts on the shaft and inside the housing to retain lubricant and block the entry of dust, water or particles. Its A 103 design and its dimensions of 52 mm shaft, 66 mm housing and 7.50/12.00 mm height make it suitable for equipment with continuous rotation. MR Accesorios Industriales sells it as part of its seals and oil seals line.
This item is a DBH 8427 radial shaft seal, identified by the designation 8427 and the A 103 design. Its dimensions are 52 mm shaft diameter (d), 66 mm housing diameter (D) and a height (h) of 7.50/12.00 mm. The A 103 design corresponds to a seal with a sealing lip and metal body, designed to retain lubricant in applications where the shaft rotates inside a cavity. The dual height indicates that the seal can adapt to different housing depths within that range. It is a component of the radial seals and oil seals category that MR Accesorios Industriales sells as an official brand DBH.
Typical applications for a seal such as the DBH 8427 include gearboxes, pumps, electric motors, reducers and power transmission equipment. In these systems, the seal prevents oil or grease leaks and protects bearings and gears from the entry of external contaminants. It is also used in agricultural machinery, earthmoving equipment and process lines where there are rotating shafts with permanent lubrication. Its compact size makes it suitable for reduced mounting spaces, as long as the shaft and housing dimensions match those of the component being replaced.
To correctly select a seal, you must verify the shaft diameter, the housing diameter and the available height. In this case, the shaft must measure 52 mm, the housing 66 mm and the mounting height must be within the range of 7.50 to 12.00 mm. It is important that the shaft surface is clean, free of burrs or marks, and that the housing shows no deformation. During mounting, lubricate the seal lip and use a suitable installation tool so as not to damage it. If the equipment works at high speed or temperature, consult MR Accesorios Industriales to evaluate the most suitable lip material.
