- Oldham couplings are a 3 piece design comprised of 2 aluminum hubs press fit CHINAMFG a center disk. Torque transmission is accomplished by mating the slots on the center disk to the drive tenons on the hubs. During operation the center disk slides on the tenons of each hub (which are orientated 90 apart) to transmit torque.
- While the couplings accommodate a small amount of angular and axial misalignment, they are especially useful in applications with parallel misalignment.
- We offers oldham couplings in set screw or clamp styles with bores ranging from 4mm to 35mm. Inch and metric hubs (set screw, clamp style, keyed, or keyless) are interchangeable and can be combined into a single coupling as long as they have the same outside diameter. Oldham coupling hubs are standard in black anodized aluminum for improved lubricity, increased life, and low inertia. Hubs are also available in stainless steel CHINAMFG request for increased corrosion resistance.
- Ideal for many light duty industrial and motion control applications, oldham couplings have the ability to protect more expensive machinery components.
- For example the oldham coupling acts as a torque limiter during overload. When the disk fails, it breaks cleanly and does not allow any transmission of power.
- Oldham couplings also have the advantage of electrical isolation due to the non-conductive nature of the center disk.
- This prevents electrical currents from being passed to delicate instruments which can cause inaccurate data readings or damage.
- High absorption capacity of radial misaligment
- They do not produce kinematic errors in transmission
- Elimination of loads on shaft
- Mechanical protection against excessive torque
- Replaceable disc

Using Jaw Couplings in Precision Motion Control Systems
Jaw couplings are versatile mechanical couplings commonly used in various industrial applications for transmitting torque between two shafts. While they offer many benefits such as simplicity, cost-effectiveness, and ease of installation, they may not be the best choice for precision motion control systems that require extremely accurate and repeatable positioning. The following factors should be considered when using jaw couplings in precision motion control systems:
- Backlash: Jaw couplings typically have some degree of backlash due to the clearance between the jaws and the spacers. This can introduce positional errors and limit the ability to achieve precise movements, especially in systems that require bidirectional positioning.
- Angular and Parallel Misalignment: While jaw couplings can accommodate some degree of misalignment, precision motion control systems often require tight tolerances and minimal misalignment to achieve accurate positioning. In such cases, more rigid and flexible couplings, such as servo couplings or beam couplings, may be preferred.
- Torsional Stiffness: In precision motion control, minimizing torsional wind-up and maintaining torsional stiffness is essential for precise and responsive movements. Jaw couplings may not provide the required level of torsional stiffness needed for high-performance motion control applications.
- Resonance and Vibration: In precision motion systems, avoiding resonance and minimizing vibration is crucial for stability and accuracy. The damping characteristics of jaw couplings may not be sufficient to suppress vibrations and resonant frequencies, which can adversely affect performance.
While jaw couplings are widely used in general industrial applications, precision motion control systems often demand more specialized and precise coupling solutions. Some alternatives that are better suited for precision motion control applications include servo couplings, beam couplings, and disc couplings. These couplings offer higher torsional stiffness, lower backlash, and better overall performance for demanding motion control requirements.
When selecting a coupling for precision motion control, it is essential to consider the specific requirements of the application, including torque, speed, misalignment, and stiffness, to ensure the chosen coupling can meet the precision and performance demands of the system.

Safety Considerations When Using Jaw Couplings in Rotating Machinery
While jaw couplings are generally safe to use in rotating machinery, there are some important safety considerations to keep in mind to ensure safe and reliable operation:
- Proper Installation: Correct installation is crucial for the safe functioning of jaw couplings. The coupling should be mounted precisely in alignment with the shafts to prevent misalignment and minimize stress on the components.
- Regular Maintenance: Regular inspection and maintenance are essential to identify signs of wear, misalignment, or damage. Any issues should be addressed promptly to prevent potential failures that may compromise safety.
- Load Capacity: Ensure that the selected jaw coupling has an adequate load capacity for the specific application. Overloading the coupling can lead to premature failure and safety risks.
- Operating Speed: Be mindful of the operating speed limitations of the jaw coupling. Operating the coupling beyond its maximum rated speed may result in excessive wear and potential hazards.
- Environmental Factors: Consider the environmental conditions in which the jaw coupling will operate. Extreme temperatures, humidity, or corrosive substances may impact the coupling’s performance and longevity.
- Emergency Shutdown: Implement an emergency shutdown procedure to quickly stop the machinery in case of any unexpected issues or safety concerns.
- Guarding and Enclosure: Depending on the application, consider using protective guarding or enclosures to prevent accidental contact with rotating components and ensure operator safety.
- Compliance with Standards: Follow industry standards and regulations relevant to the specific application to ensure compliance and adherence to safety guidelines.
By adhering to these safety considerations, operators and maintenance personnel can help minimize the risk of accidents, protect personnel from potential hazards, and ensure the reliable and safe operation of rotating machinery with jaw couplings.
