Walkersele OSJ-2

Supplier: James Walker

Walkersele OSJ is James Walker's patented and highly successful technique for the On-Site Joining of split-type Walkersele radial lip seals.


For many years, on-site vulcanising was the only answer to split-seal assemblies where leakage was unacceptable. But this process could prove expensive, as it needed a high level of skill and elaborate jigs. So we developed Walkersele® OSJ. 

Since the introduction of Walkersele® OSJ in 1992, rotary seal replacement has come 'full circle' to form a full circle again. 

After a few hours of hands-on training, a maintenance fitter is able to produce a securely bonded seal that provides a split Walkersele® with the integrity of a fully moulded endless seal.

The many benefits of Walkersele® OSJ include:

  • High performance - installed units provide the sealing performance of high-integrity endless Walkerseles.
  • Wordwide proven - on marine propulsion systems, gearboxes, power stations, sugar refineries, etc...
  • Cost effective maintenance - the performance and integrity of an endless-type seal is achieved without major plant strip-down and without exspensive on-site vulcanising.

Walkersele® OSJ-2
In consultation with longterm OSJ® customers, we have modified the installation kit to make it easier and more efficient to use under arduous maintenance conditions and at large diameters.

With Walkersele® OSJ-2, you get exactly the same top-quality lip seal and high-integrity jointing system as with our original Walkersele® OSJ system. Improvements include:

  • New user-friendly clamping band with finer tension control.
  • Redesigned jig to provide a more positive location of seal joint.
  • Improved temperature indicator.
  • Availability in larger diameters.

Your on-site joining kit
Every Walkersele® OSJ-2 kit contains the following:

  • The correct Walkersele® as specified. This seal is specially adapted at joint interface for OSJ® installation. 
  • Steel clamping band.
  • Joining jig - precision moulded in synthetic elastomer.
  • Nut-driver to adjust clamping band.
  • Temperature indicator with self-adhesive backing.
  • Two-part epoxy adhesive in sachet. This adhesive cures to semi-rigid state. (Note: hot air gun is needed to cure this adhesive). 
  • Degreasing cloth, abrasive stick, adhesive applicator brush, and emery paper with self-adhesive backing.
  • Full step-by-step instructions.
