Every 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.
Our family of high efficiency lip seals for rotary applications is extensively proven worldwide for longterm bearing protection on plant as diverse as rolling mills, gearboxes, marine propulsion systems, process mixers and tunnel boring machines. 
Walkersele® OSJ is our unique and patented technique for the on-site joining of radial lip seals. It enables a Walkersele® to be fitted with the ease and maintenance economies of a split type - and provides the high-integrity sealing performance of an endless seal. 
The slow oscillating blade roots of Kaplan turbines used in hydropower generation present particular maintenance problems. Our seals have been specifically designed, developed and proven for their long operational life and ease of replacement in the confined working environment, thus cutting turbine downtime to the minimum. 
We supply a vast range of competively priced metal cased lip seals in combinations of design and size in standard materials.
