A flexible coupling with an outer diameter (OD) of 25mm, a length (L) of 32mm, and a bore size of 5x5mm is typically used to connect two shafts that need to transmit torque while accommodating slight misalignments. Here are some specific details about such a coupling:


  • Outer Diameter (OD): 25mm
  • Length (L): 32mm
  • Bore Diameter: 5mm on both ends (5x5mm indicates both shafts to be connected have a 5mm diameter)

Key Features:

  1. Material:
    • Common materials include aluminum, stainless steel, or certain plastics, depending on the application’s torque and environmental requirements.
  2. Flexibility:
    • Designed to compensate for angular, parallel, and axial misalignments.
    • May include features like helical cuts, rubber inserts, or other flexible elements to enhance flexibility.
  3. Torque Transmission:
    • Efficient in transmitting torque between connected shafts while reducing stress on the shafts and bearings due to misalignment.
  4. Applications:
    • Commonly used in servo motors, stepper motors, encoders, lead screws, and other precision machinery.

Example Usage:

In an application where you need to connect a stepper motor with a lead screw, a flexible coupling of the specified dimensions will ensure that any misalignment between the motor shaft and the lead screw does not result in undue stress on the components, thereby enhancing the longevity and performance of the system.

Installation Tips:

  1. Ensure Correct Bore Alignment:
    • Make sure that the shafts are properly aligned with the coupling bores to minimize initial misalignment.
  2. Tighten Set Screws:
    • Most flexible couplings use set screws or clamps to secure the shafts. Tighten these securely to prevent slippage.
  3. Check for Misalignment:
    • After installation, manually rotate the shafts to ensure that the coupling accommodates any misalignment without excessive resistance.

Using a flexible coupling with the specified dimensions is a practical solution for many precision applications where maintaining alignment and reducing mechanical stress is critical.

Features :

  1. Corrosion resistance and High Durability
  2. One piece construction with long-lasting performance
  3. Torsional stiffness: Zero backlash
  4. Low moment of inertia offering constant velocity
