The DBH 8271Pol is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With a 74 mm shaft, 90 mm housing and 10 mm height, it fits assemblies where axial space is tight. Its Mx-R design combines a sealing lip with a metal case for press-fit installation. MR supplies this seal and can help you confirm the right reference for your application.
This seal belongs to the DBH line and carries the code 8271Pol. The dimensions are 74 mm for the shaft, 90 mm for the housing bore and 10 mm for the height. The Mx-R designation indicates a lip seal with a metal outer body that presses into the housing and seals against the shaft. By referencing 8271Pol, you can check material or spring options if your operating conditions call for them.
Seals of this size are common in gearboxes, centrifugal pumps, electric motors, rollers and transmission shafts. Their job is to hold oil or grease inside the assembly and block dust and water from entering. In equipment that runs continuously, a failed seal can lead to lubricant loss, bearing damage and unexpected downtime.
Before installing, inspect the shaft for hardness, roughness and any burrs or marks that could harm the lip. The housing should be clean and undistorted. Lubricating the lip with the system oil helps insertion. The 10 mm height suits shallow cavities, but the seal must sit fully seated and square to the shaft. For high vibration or temperature, ask about alternative materials.
If you are replacing this seal, we can source a compatible equivalent based on your shaft and housing dimensions. Just send the part number 8271Pol or the three measurements. We can also quote different material grades to match the fluid and temperature. The goal is to keep your equipment running without sealing-related delays.
