Gear Couplings

Request InformationFalk Lifelign Gear Couplings’ triple-crowned teeth are crowned on the root, tip and face to articulate freely and minimize wear caused by misalignment. By eliminating tip-loading while reducing backlash and radial clearances, Lifelign’s triple-crown teeth can help protect equipment from damaging loads.
