The DBH 8412Pol radial shaft seal keeps lubricant contained and blocks dust, water, and other contaminants from entering rotating equipment. It has an Mz-R design and measures 30 mm at the shaft, 43 mm at the housing, and 8 mm in height. MR Industrial Accessories supplies this seal and can help you confirm the right fit for your application.
As a wear component, the 8412Pol is replaced during scheduled or corrective maintenance. Its Mz-R configuration combines a sealing lip with a spring, making it suitable for rotating shafts that run with lubrication. The elastomer lip and metal case handle continuous friction while maintaining the seal.
You will find this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and belt or chain drives. It also appears in machine tools, conveyors, and agricultural or road equipment. In each case, the seal keeps oil or grease inside the assembly and protects bearings and gears from outside contamination.
When selecting a replacement, match the shaft diameter, housing bore, and height to your equipment. The Mz-R design works for shafts turning in one direction at moderate speeds. If your setup calls for a different configuration, ask us. During installation, lubricate the lip with the same oil used in the machine, press the seal in squarely, and avoid hitting it. Check that the shaft is free of burrs or wear that could harm the lip.
If code 8412Pol is not available or you need an equivalent, we can source a seal with the same dimensions from another brand or series. Just send the shaft diameter, housing diameter, and height, or the code stamped on the old seal. We can also advise on the elastomer type based on the fluid and operating temperature.
