✅ Material: aviation-grade aluminum housing with corrosion resistance and red anodized finish
✅ Spider: six-pronged elastomer for flexible torque transfer and shock absorption
✅ Applications: CNC machines, servo motors, spindles, and stepper drives
✅ Installation: easy to connect between motor and driven shaft; durable construction

💡 What is a shaft coupling used for in hobby CNC and 3D printer setups?

This handy connector keeps torque flowing between motor and driven shaft while allowing minor misalignment. - Helps align shafts and transmit torque between motor and load.
- Absorbs minor misalignment and shock to extend bearing life.
- Made of aluminum with elastomer spider for durability in automated rigs.
- Ideal for stepper and servo motors in 3D printers and CNC machines.
