TLC coupling range is particularly suited for high-torque electric motor or turbine drives in critical process industry, marine and power generation. Torque is transmitted through two sets of membranes, separated by a spacer element, and protected by two adaptable guard rings in a pre-assembled transmission unit. The coupling provides a good level of angular, lateral and axial misalignment, while maintaining a high level of balance integrity. Options for spark resistance, electrical insulation, limited end float and torque limiting are available. This coupling is the preferred choice for API applications where high torques are required. It is an eight-link, all-metal membrane coupling with imperial fasteners.
