The DBH 9018 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its dimensions are 165 mm shaft, 190 mm housing and 15 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment running on large-diameter shafts. MR Accesorios Industriales carries this brand and advises you on choosing the right seal.

The DBH 9018 is an Lx design oil seal, with the three standard dimensions: 165 mm shaft diameter (d), 190 mm housing diameter (D) and 15.00 mm height (h). The Lx design indicates a particular construction of the lip and the metal case, which defines how it seats on the shaft and how it is fixed in the bore. These are the dimensions you must verify before ordering: any difference in shaft diameter or housing depth prevents correct installation.

Seals of this size are found in equipment with large-diameter shafts: gearboxes, speed reducers, centrifugal pumps, mills, mixers and heavy-duty transmissions. They also appear in conveyor rollers and continuous process machinery, where the main function is to prevent oil leaks and protect the bearings from contaminant ingress. In such equipment, the seal works alongside bearings and housings, and its failure is usually detected by lubricant loss or noise in the assembly.

To select a radial shaft seal, dimensions alone are not enough: shaft speed, operating temperature, lubricant type and differential pressure must be considered. The Lx design has a lip profile that adapts to shafts with some eccentricity or slight misalignment, but it is always advisable to check the condition of the shaft and housing before installation. A scored shaft or an out-of-round housing makes the seal fail even when new. If the equipment runs with heavy vibration, consider a housing or bearing that absorbs those loads better.

If you need a seal with nearby dimensions or an equivalent from another brand, send us the full part number and the shaft, housing and height dimensions. With that data we can look for an alternative within the same family or suggest a seal with a similar design. We can also guide you if the housing has a shoulder or if the shaft shows wear, so you choose the most suitable solution. The idea is that you don't buy blindly: first we confirm the part is the right one.
