HRC couplings offer a range of hub and element selection to meet the demand for a low cost, general purpose spacer type flexible coupling. They allow for incidental misalignment, absorb shock loads and dampen out small amplitude vibrations. They are offered in both pilot bore, finished bore, Finished bore, and Taper bushed with both face and hub mount.
TRASCO® couplings are dimensionally manufactured to hub types "A" and "B", the difference being the maximum shaft diameter which hubs can accpet (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" execution.
