Rotary Seals

Walkersele radial lip seals - general rangeEvery item of rotating plant and equipment - from a lawn sprinkler to a hot steel rolling mill or hydroelectric power scheme - relies on rotary sealing systems to keep it working efficiently.

The four main points to consider are...

  • Bearing protection
  • Lubricant retenion
  • Exclusion of contaminants
  • Minimising the leakage of fluid media.

James Walker caters for these needs at every industrial level with five complete families of seals, and a patented installation technique that avoids costly dismantling.


Bi-O-Lion® has been developed as part of an extensive compatibility testing programme designed to provide a clear understanding of the effect on seals and components of switching to EAL products.

Through this programme James Walker has explored the suitability of a vast range of elastomer formulations against more than 30 major EAL products currently in use.
