Product Picture
These stainless steel shaft couplers allow you to couple 2 size shafts together. They can be used for connecting motor shafts to drive shafts, or 2 different-sized shafts. These shaft couplers have a length of 0.75″, a outer diameter of 0.42″, and couple 1/4″ to 5mm shafts.
Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to 2 shafts even if they are not perfectly co-linear and will help reduce binding effects.
This coupler will connect a 5mm diameter shaft to an 8mm diameter shaft. A perfect add on for motors . Comes with 2 sets of double set-screws (two per side) for secure attachment. You’ll need a 2mm allen wrench to tighten/loosen the set-screws.

Usage of Jaw Couplings for Motor-to-Shaft and Shaft-to-Shaft Connections
Jaw couplings are versatile components that can be used for both motor-to-shaft and shaft-to-shaft connections in mechanical power transmission systems. Their design and features make them suitable for various applications:
- Motor-to-Shaft Connection: When connecting a motor to a driven shaft, jaw couplings are commonly used to transmit torque from the motor to the driven equipment. The motor’s shaft is inserted into one side of the jaw coupling, and the driven shaft is inserted into the other side. The elastomeric spider element in the coupling provides a flexible connection that accommodates misalignment and dampens vibrations, ensuring smooth power transmission from the motor to the driven shaft.
- Shaft-to-Shaft Connection: In cases where two shafts need to be connected directly, without a motor or other driving element, jaw couplings can be used for shaft-to-shaft connections. Both shafts are inserted into the respective sides of the jaw coupling, and the elastomeric spider element bridges the gap between them. This enables torque transfer between the two shafts while compensating for any misalignment that may exist.
Whether used for motor-to-shaft or shaft-to-shaft connections, jaw couplings offer the same advantages, including misalignment compensation, vibration dampening, and backlash-free operation (depending on the design). These features make them suitable for various applications across different industries, where reliable and efficient power transmission is essential.
How does a jaw coupling help in torque and rotational speed control?
A jaw coupling plays a vital role in torque and rotational speed control by facilitating efficient power transmission while compensating for misalignments and dampening vibrations. Here’s how a jaw coupling helps in achieving torque and rotational speed control:
- Torque Transmission: Jaw couplings are designed to transmit torque between two shafts with minimal power loss. The elastomer spider, which acts as the flexible element between the two coupling hubs, efficiently transfers torque from one shaft to the other. This precise torque transmission is essential in maintaining consistent rotational motion and controlling the speed of the driven equipment.
- Misalignment Compensation: In rotating machinery, misalignments between the motor and driven equipment are common due to factors like installation errors, thermal expansion, or shaft deflection. Jaw couplings can handle both angular and parallel misalignments. By accommodating these misalignments, jaw couplings ensure smooth operation and prevent unnecessary stress on the equipment, thus contributing to torque and rotational speed control.
- Vibration Damping: Vibrations are an inherent characteristic of rotating machinery and can affect torque and rotational speed stability. The elastomer spider in the jaw coupling acts as a damping element, absorbing and dissipating vibrations. This vibration damping capability reduces the risk of speed fluctuations and enhances overall system stability during operation.
- Start-Up and Overload Protection: During start-up or when the driven equipment experiences sudden overload conditions, there may be spikes in torque and rotational speed. Jaw couplings, with their torsional flexibility, can absorb these sudden torque variations, protecting the equipment from damage and providing smoother start-up and operation.
The combination of precise torque transmission, misalignment compensation, vibration damping, and overload protection makes jaw couplings effective in achieving torque and rotational speed control. However, it is essential to choose the appropriate jaw coupling size and material for the specific application to ensure optimal performance and reliability.
For applications that require even higher torque capacity or stricter speed control, specialized coupling types like gear couplings or servo couplings may be more suitable. These couplings offer advanced features for precision motion control and torque transmission in more demanding applications.
Can Jaw Couplings Accommodate High Torque and High-Speed Applications?
Jaw couplings are versatile and can handle a wide range of torque and speed requirements. However, their suitability for high torque and high-speed applications depends on the specific design and material of the coupling.
Advancements in jaw coupling technology and the use of high-strength materials, such as steel and aluminum, have significantly improved their performance capabilities. For many industrial applications, jaw couplings can efficiently accommodate high torque and high-speed requirements.
When selecting a jaw coupling for high torque and high-speed applications, consider the following factors:
- Coupling Size: Choose a jaw coupling size that matches the torque and speed requirements of the application. Larger couplings with bigger spider elements can handle higher torque loads.
- Material: Opt for jaw couplings made from robust materials like steel or aluminum, which can withstand higher torque and speed without compromising structural integrity.
- Design: Some jaw coupling designs are better suited for high torque applications, offering increased torque capacity and better performance under heavy loads.
- Service Factor: Consider the service factor, which accounts for peak or intermittent loads, to ensure the selected jaw coupling can handle temporary torque spikes.
It’s essential to consult with coupling manufacturers or industry experts to determine the most suitable jaw coupling for specific high torque and high-speed applications. Properly sized and selected jaw couplings can provide reliable and efficient power transmission in demanding industrial scenarios.
