SIT TRASCO GRMB Hubs (Taper Bored)

GRMB taper bored hubs are parts designed for SIT TRASCO shaft couplings. They are sometimes simply called as the TRASCO GRB series hubs, or labeled as GR B or GR MB.

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 GRMB hubs are made of cast iron with Taper Lock bore in B1 version with external mounting or B2 version with internal mounting.
