Contact Supplier| In the base execution, “GR” TRASCO® couplings are available in two different versions: |
| precision “P” or economy “S”. The difference between “P” and “S” type hubs is that in |
| the precision execution the circular sections of the hubs are precision machined, while in |
| the economy execution they are simply deburred. The “S” version allows lower axial |
| displacement as indicated in the technical performance table. Hubs are available in cast |
| iron GG25, die cast aluminium alloy or forged aluminium. On special request hubs are |
| available in steel or cast iron GGG40.TRASCO® couplings are dimensionally |
| manufactured to hub types “A” , “B” and "L" (long hub execution). |
