Explore the Efficiency of Oldham Clamp Coupling with HZPT

Introduction to Oldham Clamp Coupling

Oldham clamp coupling is a mechanical device designed to connect two shafts together, allowing for the transmission of torque and rotation. It is characterized by its three-part assembly: two hubs and a central disc. This design enables it to accommodate misalignment between shafts efficiently while transmitting power smoothly.

Design and Features

The Oldham coupling consists of two grooved hubs and a center disc. The disc sits between the hubs, with its grooves interlocking with those on the hubs. This configuration allows for lateral and angular misalignments while limiting axial motion.


Due to its ability to handle misalignment, Oldham clamp coupling is widely used in precision applications such as encoders, stepper motors, and other light-duty industrial applications where alignment cannot be guaranteed.


The coupling offers several advantages including easy assembly, no need for lubrication, and minimal backlash, making it ideal for precise control applications.

Key Features of Oldham Clamp Coupling

  • Tolerance to Misalignment: Capable of compensating for parallel, angular, and axial misalignments between shafts.

Working Principle of Oldham Clamp Coupling

The Oldham coupling operates by having the central disc transmit torque between the two hubs. Misalignments are accommodated by the sliding movement of the disc within the grooves of the hubs, ensuring that the shafts remain connected and torque is transmitted effectively.

How to Choose the Right Oldham Clamp Coupling

  • Determine the Application Requirements: Consider the torque, RPM, and the degree of misalignment in your application.
  • Select the Material: Choose a material that suits the environment in which the coupling will operate.
  • Consider the Size: Ensure the coupling size is compatible with the shafts to be connected.
  • Customization Options: Look for customization options that can meet specific requirements of your application.
  • Manufacturer’s Reputation: Choose a manufacturer with a proven track record for quality and reliability.

Maintenance of Oldham Clamp Coupling

Maintaining Oldham clamp coupling involves regular inspection for wear and tear, ensuring that all components are securely fastened and replacing the central disc if signs of excessive wear are observed. Proper maintenance is crucial for the longevity and performance of the coupling.
