The DBH 9425 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 40 mm shaft diameter, 85 mm housing and 8 mm height, it is used in gearboxes, pumps, electric motors and industrial equipment in general. MR Accesorios Industriales supplies this official brand and advises you so you choose the correct seal for your application.

The DBH 9425 is a seal of Lx design, with a sealing lip and metal body. Its standard dimensions are 40 mm inner diameter (shaft), 85 mm outer diameter (housing) and 8.00 mm overall height. This type of seal is press-fitted into the housing and its flexible lip contacts the rotating shaft, creating a dynamic seal that retains oil or grease and blocks external contaminants.

It is used in applications where there is rotary motion and a need for sealing: gearboxes, centrifugal pumps, electric motors, compressors, machine tools and transmission equipment. It is commonly found in environments with dust, chips or moisture, where bearings and lubricant need to be protected. Its Lx design provides a reliable solution for shafts rotating at moderate and high speeds.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of the equipment. The shaft surface must be ground and have adequate hardness to prevent premature lip wear. During assembly, lubricate the lip with the same oil or grease used in the machine, insert it perpendicular to the shaft and avoid striking it. If the shaft has a groove or wear, consider an alternative size or a repair sleeve.
