SIT TRASCO GRMP Hubs (Finished Bore)
GRMP finished bore hubs are parts designed for SIT TRASCO shaft couplings. They are sometimes simply called as the TRASCO GR series basic hubs, or labeled as GR P or GR MP.
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 GRMP hubs are made of steel or cast iron with a seating or in straight design with finished H7 bore, keyway according to DIN 6885 and bore for lock screw.
