Re‑inventing the seal

In cooperation with bearing and turbine OEMs James Walker has undertaken a comprehensive test programme covering all elements of rotary seal design. These include spring retention, lip loading, torque, friction, leakage and wear plus sealing capability at a variety of significant offsets. Testing was focused on protecting and extending the service life of critical bearing applications and drive mechanisms.

The result is a new patented seal construction specifically configured to optimise sealing capability on large diameters where increased levels of offset from loaded bearings and out-of-round shafts and seal housings can create significant issues.

This short technical paper explains the development process.
