For rotating equipment that must keep lubricant in and contaminants out, the DBH 8425Pol radial shaft seal provides a dependable barrier. This lip seal is built for shafts of 22 mm, housings of 36 mm, and a height of 7.50/11.50 mm, following the A 090 design. It is commonly specified for gearboxes, pumps, electric motors, and power transmission systems where protecting bearings and gears is critical. MR supplies this seal and can help you confirm it matches your application.
The 8425Pol belongs to the DBH line of radial shaft seals. Its key dimensions are shaft diameter 22 mm, housing bore 36 mm, and height 7.50/11.50 mm. The dual height indicates a design that may include an auxiliary dust lip or extended outer section, as defined by the A 090 construction. The primary lip rides on the shaft to retain oil or grease while blocking dust, moisture, and abrasive particles.
Typical uses for this seal include gear reducers, centrifugal pumps, electric motors, compressors, and various power transmission assemblies. In each case, the seal prevents lubricant loss and external contamination from reaching bearings and gears. It is also found in machine tools, mining equipment, and hydraulic systems that demand reliable shaft sealing.
Proper installation starts with a clean, burr-free shaft with suitable hardness and surface finish. Apply a light film of lubricant to the lip, then press the seal evenly into the housing using a tool that contacts the outer ring. Consider shaft speed, operating temperature, and the fluid being sealed. If a previous seal failed, inspect the shaft and housing for wear or damage before fitting the new one.
If you need a replacement or a close equivalent, provide the code 8425Pol or the three dimensions of your current seal. MR can search its seal range for matching or alternative options. The team can also advise whether a different height or design might fit your available space and operating conditions.
