Why choose this rigid coupling?
1. Guaranteed Precision with Zero Backlash
This rigid coupling is engineered for applications where positional accuracy is critical. It completely eliminates backlash, ensuring perfect synchronization between connected shafts. This makes it ideal for stepper and servo motors in CNC machinery, robotics, and automation systems where even minimal torsional windup can cause significant errors.
2. Optimal Strength-to-Weight Ratio
Constructed from high-strength aluminum alloy, it provides exceptional rigidity and torque capacity (up to 220 N.M) while being remarkably lightweight. This reduces the system’s moment of inertia, allowing for faster acceleration and deceleration of motors without sacrificing performance or durability.
3. Superior High-Speed Performance
With a maximum speed rating of 39,000 RPM, this coupling is built for high-speed applications. Its precision-machined balance ensures smooth, vibration-free operation even at extreme rotational speeds, protecting your sensitive bearings and other drive components.
4. Easy, Damage-Free Installation
The innovative clamping screw design ensures a secure and concentric grip on the shaft without the need for keyways, preventing fretting corrosion and shaft damage. This simplifies maintenance and allows for quick disassembly and reassembly, minimizing downtime.
