The DBH 8412Vit radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 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 power transmission equipment to retain lubricant and stop dust and water from entering. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH 8412Vit radial shaft seal, identified by its 8412Vit designation. 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. DBH is an official brand that MR carries, so the replacement part is identified by its original part number.

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 serves 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 operates with a lot of dirt or water, it is advisable to check the condition of the lip before replacing it.

To install a radial shaft seal, check the condition of the shaft and the 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 fitting 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 the alignment, shaft runout and operating temperature.

If you need an equivalent seal or a nearby size, the most practical thing is to send us the 8412Vit part number or the shaft, housing and height dimensions. With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the Mz-R design is not the right one for your application and another lip type or material should be evaluated. The more data you give us — type of equipment, lubricant and operating conditions — the better the proposal will be.
