T2 & T25 Shaft Wheels Assemblies (January 01, 2000)


  • Production of some of our T2 and T25 shaft wheels assemblies will soon be moved form our French, Thaon-Les Vosges plant to Skelmersdale in the UK.

  • The French plant currently welds the shaft and wheels using the Inertia ( or frition ) welding process. When we change over to Skelmersdale, they will be welded using the newer Electron Beam welding process.

  • A computer controlled Electron Beam produces a very closely controlled, consistent weld between the semi-finished shaft and wheel head. After welding, no stress relieving process is needed and minimal machining to achieve the finished SWA.

  • After welding, the SWAs are 100% inspected by Ultra Sonic Testing of the welded area to ensure quality and reliability.

  • The change over represents a considerable investement in new machinery and test equipment.

  • Part number will change, but the SWA are totally interchangeable:

  • The changes will take place as soon as existing stocks are exhausted. After that, any existing orders for old part numbers will be automatically changed over from you.
