The DBH 9331 radial shaft seal is a lip seal that is mounted in the housing and seals against the shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 32 mm shaft, 42 mm housing bore and 7 mm height place it in the range of compact seals for transmission equipment and general machinery. MR Accesorios Industriales carries this brand and helps you identify the replacement if the original code has changed.

This item is an Lx design oil seal with the following dimensions: shaft diameter 32 mm, housing bore diameter 42 mm and height 7.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The 9331 nomenclature identifies the dimensional combination within the DBH line, and the code can be read directly on the product or its packaging. If your measurement does not exactly match these values, it is advisable to check the condition of the shaft and housing before defining the replacement.

Typical applications for a 32 x 42 x 7 mm oil seal include gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is a wear part, so its replacement is usually scheduled together with that of the bearings in the same assembly.

To install it, verify that the shaft has no burrs or deep marks in the lip contact area and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the oil seal with a support tube that rests on the outer diameter, never on the lip. The 7.00 mm height defines how far it protrudes from the housing, so respect the original position so as not to leave the lip outside the sealing track.

If you need an equivalent or a nearby size, send us the code 9331 along with the shaft, housing bore and height dimensions you measured, and a photo of the old oil seal if you have it on hand. With that data we review the DBH line and compatible alternatives.
