The DBH 9818/85 oil seal is a single-lip radial seal that mounts on the shaft and inside the housing to retain oil or grease and prevent the entry of contaminants. With dimensions of 23 mm shaft diameter, 41 mm housing and 8 mm height, it is a common replacement part in gearboxes, pumps and electric motors. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your equipment.

This item is a DBH radial shaft seal with designation 9818/85. Its nominal dimensions are 23.00 mm shaft diameter (d), 41.00 mm housing diameter (D) and 8.00 mm height (h). The indicated design is A 016, which corresponds to a single sealing lip with spring. These dimensions are the ones you must verify against the shaft and housing before ordering, because a seal with a different height or diameter does not seat correctly and loses sealing.

Seals of this size are used in equipment with small-diameter transmission shafts, such as gearboxes, centrifugal pumps, electric motors, compressors and machine tools. They also appear in food and process industry applications where lubricant must be contained and dust or wash water kept out. The choice of lip and spring material depends on the working temperature and the type of fluid, so it is advisable to confirm that data before replacing.

To install a radial shaft seal, the shaft must be clean, free of burrs or deep marks in the contact area, and the housing must be in good condition with the entry chamfer in good shape. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a support tube that pushes on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or a seal with an offset lip.

If you need an equivalent or a close size, send us the old code, a photo of the part and the dimensions taken with a caliper: shaft diameter, housing diameter and height. With that data we search within the DBH line or another alternative that fulfills the same function. We can also guide you if the original seal has a double lip, spring or a particular geometry that is not visible to the naked eye.
