Frequently Asked Questions
Q: What bore sizes are compatible with the D56L63 double diaphragm disc coupling?
A: The D56L63 double diaphragm shaft coupling accommodates inner diameters (bore sizes) ranging from 11 mm to 20 mm, making it versatile for a variety of stepper motor shafts and ball screw spindles in that range.
Q: What makes a double diaphragm disc coupling different from a standard flexible coupling?
A: A double diaphragm disc coupling uses two stainless steel diaphragm elements to simultaneously handle eccentricity, angular misalignment, and axial deviation while maintaining very high torsional rigidity. This results in more precise motion transfer compared to jaw-type or bellows couplings, especially in high-accuracy CNC and motion-control systems.
Q: Can this coupling handle high-temperature industrial environments?
A: Yes. The D56L63 disc coupling is rated for an operating temperature range of –80°C to +300°C, allowing it to function reliably in demanding industrial and high-temperature drive applications without loss of performance.
Q: Is this coupling suitable for precision ball screw assemblies?
A: Absolutely. The high torsional rigidity and up to 99.86% transmission efficiency of this double diaphragm disc coupling make it an excellent choice for ball screw and lead screw assemblies where accurate, low-backlash torque transmission is essential.
