About this item
🔧 Flexible Shaft Coupler 5 mm → 8 mm (Jaw/Spider Type)
💡 Shock-Absorbing Motion Coupler
The Jaw/Spider Flexible Shaft Coupler (5 mm → 8 mm) provides smooth and reliable torque transfer between shafts of different diameters. Its red elastomer spider insert absorbs vibration, compensates misalignment, and protects motor bearings in CNC, robotics, and automation systems.
🛡️ Built-In Mechanical Benefits
- 🧩 Red elastomer spider for vibration damping
- 🔄 Torsional flexibility for smoother rotation
- ⚙️ Compensation for angular & parallel misalignment
- 🧱 CNC-machined aluminum hubs
- 🔒 Dual set-screw locking
- 🔕 Low backlash for precision motion
📦 Compact & Durable Design
The coupler’s two-piece aluminum hub design isolates shock loads and prevents metal-to-metal contact. Ideal for stepper motors, precision axes, and motion-control assemblies where stability and longevity matter.
🛠️ Applications
- 🤖 Robotics & mechatronics
- 🖨️ 3D printers (Z-axis, extruders, linear drives)
- 🏗️ CNC machines (routers, mills, lathes)
- ⚙️ Stepper motor systems
- 📐 Precision actuators
- 🔩 DIY automation & machinery
⚠️ Notes
- 🔧 Tighten both set screws evenly for proper alignment.
- 🧩 Elastomer spider insert is replaceable.
- ⚠️ Not intended for very high-torque industrial loads.
