TRASCO GRMP hub for machining

SIT TRASCO half couplings, pre-bored, ready for the bore and keyway to be cut to the shaft size. TRASCO is a flexible jaw coupling with a spider in the middle, equivalent to the ROTEX of the same size.

Each size has two versions: A, for smaller bores, and B, which takes the maximum bore of the size (for example, on the 55/70, up to 55 mm on A and up to 70 mm on B). The long version (L) covers the whole motor shaft. The hubs are in GG25 cast iron from size 24/32; the keyway, when cut, follows DIN 6885-1 with JS9 tolerance.

Choose the size and version in the list; the dimensions of each are in the attached catalogue.
