The DBH 9481Vit radial shaft seal is a lip seal that mounts on an 18 mm shaft and seals against a 30 mm housing, with a height of 6 mm. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in equipment with small-section rotating shafts, where axial space is limited.

This item is identified by the designation 9481Vit and corresponds to a seal with an Lz design. Its dimensions are 18 mm shaft, 30 mm housing and 6.00 mm height. The Lz design refers to a single-lip configuration with a spring, intended for rotating shafts with permanent lubrication. The manufacturer's nomenclature allows the part to be located by code rather than by loose dimensions, which is useful when replacing a seal already installed.

Seals in this section are used in small gearboxes, electric motors, centrifugal pumps, compressors, machine tools and transmission equipment. They also appear in agricultural implements and in conveyor lines where shafts rotate inside a fixed housing. In all these cases the seal performs the same function: separating the lubricated side from the environment and preventing oil or grease from migrating outward.

To select a seal, you must verify the shaft diameter, the housing diameter and the available height. The type of lubricant, the working temperature and the peripheral speed of the shaft also matter, because the lip material depends on them. A poorly chosen lip crystallizes or wears out quickly. If the shaft has burrs, it is advisable to polish the contact area before mounting the new part.

During installation, lubricate the lip with the same grease or oil used in the equipment and seat the seal perpendicular to the shaft. Strike on the outer circumference, never on the lip, with a tube or shim of suitable diameter. If the housing has a shoulder, verify that the seal seats fully. Once in place, turn the shaft by hand to check that there is no rubbing or deformation of the lip.

If you need a nearby size or an equivalent, send the code 9481Vit by WhatsApp to MR Accesorios Industriales along with the shaft and housing dimensions. You can also send a photo of the old seal or the assembly drawing. With that data, the compatible part is found within the DBH line that MR carries and the quote is confirmed.
