Application:
FAQQ1. Are you a manufacturer or a trader?
Manufacture, we have 5 own foundries, 4 in ZheJiang Province, 1 in ZHangZhoug Province
Q2. Do you have MOQ request?
1 pcs per order is ok with us , unless material is seldom used.
Q3. If I only have a sample,without drawings, can you quote then manufacture for me?
Just send us the sample, we would have the sample simulated and measured by professional equipment then issue formal drawings for
you , at the same time, we could help you optimize the design according to your demand and related processes’ feasibility.

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.
What are the common installation mistakes to avoid when using jaw couplings?
Proper installation of jaw couplings is crucial to ensure their reliable and efficient operation. Avoiding common installation mistakes can prevent premature wear, misalignment, and potential equipment damage. Here are some of the most common installation mistakes to avoid when using jaw couplings:
- Incorrect Coupling Size: Using the wrong size of jaw coupling for the application can lead to various issues. Undersized couplings may not handle the required torque, leading to early failure, while oversized couplings may result in increased rotational inertia and decreased system performance. Always ensure that the selected coupling is appropriate for the torque and power requirements of the equipment.
- Misalignment: Improper alignment of the shafts during coupling installation can cause excessive forces and premature wear on the coupling components. Angular, parallel, and axial misalignments should be minimized and kept within the manufacturer’s recommended tolerances. Consider using alignment tools and techniques to achieve accurate shaft alignment.
- Over-Tightening: Applying excessive torque when tightening the coupling elements can lead to deformation of the elastomer spider or damage to the hubs. Over-tightening can also increase friction and cause premature wear. Follow the manufacturer’s specified torque values during installation to ensure proper clamping without causing damage.
- Lack of Lubrication: Some jaw couplings require lubrication to reduce friction and wear. Neglecting to lubricate the coupling elements can lead to increased friction, higher operating temperatures, and reduced coupling life. Follow the manufacturer’s guidelines regarding lubrication intervals and types of lubricants to use.
- Failure to Inspect Components: Before installation, carefully inspect all coupling components for any signs of damage, wear, or defects. Using a damaged or worn-out elastomer spider or other components can compromise the coupling’s performance and reliability. Replace any worn or damaged parts before installing the coupling.
- Improper Shaft End Preparation: Ensure that the shaft ends are clean, smooth, and free from burrs or imperfections before installing the coupling. Rough or uneven shaft surfaces can lead to misalignment and reduce coupling performance. Properly clean and prepare the shaft ends to ensure a secure and accurate fit.
- Not Following Manufacturer’s Guidelines: Each jaw coupling has specific installation instructions provided by the manufacturer. Failure to follow these guidelines can result in coupling failure or reduced performance. Always refer to the manufacturer’s installation manual and recommendations for proper installation procedures.
By avoiding these common installation mistakes, users can maximize the performance and longevity of jaw couplings in their applications. Proper installation ensures that the coupling operates efficiently, transmits power effectively, and reduces the risk of unexpected failures or downtime.
Handling Angular, Parallel, and Axial Misalignment with Jaw Couplings
Jaw couplings are designed to handle various types of misalignment that can occur between the shafts they connect. These misalignments include:
- Angular Misalignment: When the shafts are not aligned in a straight line and have an angular offset, jaw couplings can accommodate this misalignment due to the flexibility of their elastomeric spider. The spider allows for a limited amount of angular movement between the hubs, reducing stress on the connected equipment.
- Parallel Misalignment: Parallel misalignment occurs when the shafts are not perfectly aligned but are parallel to each other. Jaw couplings can handle parallel misalignment to some extent, thanks to the elastomeric spider’s ability to flex and offset slight shaft misalignments.
- Axial Misalignment: Axial misalignment refers to the displacement of shafts along their rotational axis. While jaw couplings are primarily designed for torque transmission and misalignment compensation, they have limited capability to handle axial misalignment. Excessive axial misalignment can lead to premature wear and reduce the coupling’s effectiveness.
It’s important to note that jaw couplings have specific misalignment limits, and exceeding these limits can lead to increased wear and decreased performance. Regular maintenance and inspection of jaw couplings are essential to ensure they are operating within acceptable misalignment parameters.
