Keyway according to DIN 6885 sheet 1 - JS9 Alternative materials used for manufacture are: » sintered steel (see note above) » cast iron grade GG25 » aluminum, die-casting » ductile cast iron grade GGG40 and steel upon request. Approved according to ATEX directive. ® TRASCO couplings are dimensionally manufactured to hub types “A” and “B”, the difference being the maximum shaft diameter which hubs can accept (corresponding respectively to the first and second code number). The long hub execution “L”(allows full coverage of the motor shaft) is available in both “A”and “B” executions. Size Fa max. (mm) Fb max.
