JKL FLEXIBLE BELLOW COUPLING ID19/12 X OD 45 X LENGTH 63

A flexible bellow coupling (also called a bellows coupling) is a type of mechanical coupling used to connect two shafts while allowing for angular, axial, and parallel misalignment. It's commonly used in precision motion systems like CNC machines, servo motors, and encoders due to its zero backlash, high torsional rigidity, and flexibility.

 Key Features:

• Material: Usually stainless steel bellows; hubs may be aluminum or steel.
• Design: Thin-walled metal bellows that flex to absorb misalignment.
• Torque Transmission: High precision with no backlash.
• Misalignment Compensation:
  • Axial: ±0.2 to ±0.5 mm (typical)
  • Angular: up to 5°
  • Parallel: up to 0.3 mm
• Speeds: Suitable for high-speed applications.

 Advantages:

• Zero backlash (ideal for servo systems)
• High torsional stiffness
• Compensates for misalignments
• Low moment of inertia
• Maintenance-free

 Limitations:

• Not suitable for very high torque or shock loads
• Can be more expensive than other couplings
• Limited misalignment capacity compared to jaw or disc couplings

 Applications:

• CNC machinery
• Robotics
• Servo motors
• Encoders
• Linear actuators
• Measuring systems
