The DBH 8638 oil seal is a radial seal with a 52 mm shaft diameter, 67 mm housing diameter and 7.50 mm height, with an A 095 design. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles, working on a rotating shaft. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this official brand and advises you on choosing the right oil seal for your application.

This item is a DBH radial oil seal, identified by the code 8638. Its dimensions are 52 mm shaft diameter (d), 67 mm housing diameter (D) and 7.50 mm height (h). The A 095 design corresponds to a single lip with spring, intended for rotating shafts with lubrication. The elastomeric lip rests on the shaft and closes off the oil passage, while the outer body fits into the housing. It is a wear part that should be replaced when lubricant leakage or dirt ingress appears.

Typical applications for an oil seal of this size include gearboxes, reducers, centrifugal pumps, electric motors, drive shafts and process equipment. In all cases it performs the same function: confining the oil or grease inside the assembly and blocking external contaminants. It is also used in machine tools, material handling equipment and hydraulic systems where the shaft rotates inside a fixed housing. If the equipment operates with heavy vibration or temperature, it is advisable to check the condition of the shaft before mounting.

To select and mount an oil seal such as the 8638, verify that the shaft and housing dimensions match those of the original component. The shaft must be clean, free of burrs or deep marks in the contact area, and the housing free of deformation. Lubricate the lip before inserting it and place the oil seal perpendicular, without striking it directly on the elastomer. If the shaft shows wear, consider a repair sleeve or an alternative size. Correct alignment and a suitable shaft surface extend the service life of the seal.
