The DBH 8412Vit radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With 30 mm shaft diameter, 43 mm housing diameter and 8 mm height, and an Mz-R design, it is used in gearboxes, pumps, electric motors and transmission equipment to retain lubricant and stop the ingress of dust and water. MR Accesorios Industriales sells it as part of its line of seals and oil seals.

This item is a DBH 8412Vit radial shaft seal, identified by its designation 8412Vit. Its dimensions are 30 mm shaft, 43 mm housing and 8.00 mm height, with an Mz-R design. That combination of dimensions and lip geometry defines the seat in the housing and the contact on the shaft. The Mz-R design corresponds to a single-lip seal with spring, intended for rotating shafts with permanent lubrication. The DBH brand is a brand MR sells, so the replacement part is identified by its original code.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In all those cases the seal performs two functions: retaining the oil inside the assembly and preventing contaminants from entering from outside. It is also found in power transmission equipment, where it protects the bearings and extends the service life of the assembly. If the equipment works with a lot of dirt or water, it is advisable to check the condition of the lip before replacing it.

To mount a radial shaft seal, check the condition of the shaft and housing. The shaft must not show burrs, deep scratches or wear in the contact area, and the housing must be clean and free of deformation. Before installing the seal, lubricate the lip with the same grease or oil used in the equipment. Installation is done with a tube or press that bears on the outer diameter, never on the lip. If the previous seal failed, check alignment, shaft runout and working temperature.

If you need an equivalent seal, the most practical thing is to send us code 8412Vit or the shaft, housing and height dimensions. With that data we can look for an alternative within the DBH line or other brands we sell. We can also guide you if the Mz-R design is not suitable for your application and it is worth evaluating another type of lip or material. The more data you give us — type of equipment, lubricant and working conditions — the better the proposal will be.
