SIT TRASCO GRFCF Hubs (with Flange)
GRFCF flange hubs are parts designed for SIT TRASCO shaft couplings. They are sometimes called as CF type of TRASCO GRF series hubs, labeled as GRF CF.
SIT TRASCO are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. These GRFCF hubs are designed for flange mounting.
