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.

Using Jaw Couplings in Hydraulic and Pneumatic Systems

Yes, jaw couplings can be used in both hydraulic and pneumatic systems to connect the driving and driven components. Jaw couplings are versatile and well-suited for various power transmission applications, including those involving fluid-based systems. Here’s how jaw couplings are compatible with hydraulic and pneumatic systems:

• Flexibility: Jaw couplings are made of flexible materials, such as elastomers, which allow for some angular, parallel, and axial misalignment between the shafts. In hydraulic and pneumatic systems, where vibrations and movements are common, the jaw coupling’s ability to accommodate misalignment helps reduce stress on the connected components.
• Shock Absorption: Hydraulic systems often experience pressure surges and hydraulic shocks due to rapid changes in fluid flow. Similarly, pneumatic systems may encounter air pressure fluctuations. Jaw couplings can absorb shocks and vibrations, protecting the system from sudden jolts and minimizing wear on components.
• Corrosion Resistance: Some jaw couplings are available in materials that offer excellent corrosion resistance, making them suitable for hydraulic systems working with hydraulic fluids and pneumatic systems handling compressed air, which may contain moisture.
• Low Inertia: Jaw couplings have low inertia, which is advantageous in applications where quick start-stop responses are required. This characteristic is beneficial in hydraulic and pneumatic systems that need rapid and precise movements.
• Backlash Prevention: Backlash, which can lead to vibrations and inaccuracies, is minimized with jaw couplings. This feature is beneficial in hydraulic and pneumatic systems where precise positioning is crucial.
• Simple Installation: Jaw couplings are easy to install and require minimal maintenance, making them suitable for various hydraulic and pneumatic applications.
• Compatibility with Shaft Sizes: Jaw couplings are available in different sizes and configurations, allowing for compatibility with various shaft diameters commonly found in hydraulic and pneumatic systems.

Overall, jaw couplings offer reliable power transmission in hydraulic and pneumatic systems, providing benefits such as flexibility, shock absorption, corrosion resistance, low inertia, and backlash prevention. However, it’s essential to consider factors such as operating conditions, temperature, and the type of fluid used when selecting a jaw coupling for a specific hydraulic or pneumatic application.

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.

Advantages of Using Jaw Couplings in Mechanical Systems

Jaw couplings offer several advantages in mechanical systems:

• Misalignment Compensation: Jaw couplings can tolerate angular, parallel, and axial misalignments between connected shafts, reducing the need for precise alignment during installation.
• Vibration Damping: The elastomeric spider in the jaw coupling absorbs shocks and vibrations, providing smoother operation and extending the life of connected equipment.
• Backlash-Free: Due to the tight fit between the jaws and the spider, jaw couplings are virtually backlash-free, enabling more accurate and responsive motion transfer.
• High Torque Capacity: Jaw couplings can handle high torque loads, making them suitable for a wide range of industrial applications.
• Easy Installation: With a simple design and few components, jaw couplings are easy to install and maintain.
• Cost-Effective: Compared to other types of couplings, jaw couplings are relatively cost-effective, providing reliable power transmission at a lower cost.
• Fail-Safe Design: In the event of a spider failure, the jaws can still maintain some torque transmission, allowing for limited operation and preventing sudden breakdowns.

Due to these advantages, jaw couplings are widely used in pumps, motors, fans, and various industrial machinery where misalignment, vibration, and torque transmission are critical factors.
