Great value for money
Compared to other brands, this offers similar performance at a better price point. Highly recommended for hobbyist CNC machines.
Q: Is this compatible with NEMA 23 motors?
A: Yes, we offer bore sizes that fit NEMA 23 motors. Please select the appropriate bore combination when placing your order.
Q: Can this handle axial misalignment?
A: Yes, the raised flange diaphragm design allows for compensation of axial, angular, and parallel misalignments within specified limits.
Q: What is the maximum RPM rating for this coupling?
A: While specific ratings depend on the bore size, these couplings are generally rated for high-speed servo applications up to 4000 RPM. Please check the detailed spec sheet for your specific size.
Q: Do I need special tools for installation?
A: No special tools are required. Standard hex keys and a torque wrench for tightening the set screws to the recommended specification are sufficient.
Q: Does this coupling support both single and double lamina configurations?
A: Yes, this model is designed to accommodate both single and double lamina types depending on your specific torque and flexibility requirements.
