When selecting flexible coil spring couplings, understanding their specific applications is crucial. These components are designed to absorb shock, dampen vibration, and accommodate misalignment, making them vital for reliable mechanical system operation. Choosing the correct coupling ensures longevity and performance for your equipment.
Material: Aluminum alloy; Connection Diameter: 5mm to 8mm; Total Length: 25mm /0.98 inch; Outside Diameter : 19mm/ 0.75 inch
Zero backlash. One-piece metallic spring coupling. For little torque shaft connect.
Absorption of parallel, angular misalignments and shaft end-play by spring action.
Widely used in drive systems for encoders, instrumentation,lead screws, small pumps, feed rollers and anywhere light to medium duty, torsionally flexible coupling is required.

How to Choose the Best Flexible Coil Spring Couplings
Material Selection
Aluminum: Lightweight and corrosion-resistant, suitable for general-purpose applications where high torque is not a primary concern.
Stainless Steel: Offers superior strength, corrosion resistance, and durability, making it ideal for demanding environments or applications requiring high precision.
Torque and Speed Ratings
Consider the maximum torque the coupling will need to transmit. Exceeding this limit can lead to failure.
Ensure the coupling's speed rating is appropriate for your application to prevent excessive wear or operational issues.
Shaft Size and Alignment Accommodation
Measure the diameters of the shafts you need to connect accurately. Couplings come in various bore sizes.
Note the degree of misalignment (angular, parallel, axial) your system experiences. Coil spring couplings are effective at absorbing moderate misalignment.
Frequently Asked Questions
What is a flexible coil spring coupling?
A flexible coil spring coupling is a mechanical device that connects two rotating shafts. It uses a coiled spring to absorb shock, dampen vibration, and accommodate shaft misalignment.
What are the main benefits of using a coil spring coupling?
These couplings offer excellent vibration damping and shock absorption capabilities. They can also compensate for angular, parallel, and axial misalignment between shafts, reducing stress on connected components.
How do I determine the correct size coupling?
You need to measure the diameter of both shafts you intend to connect. Ensure the bore sizes of the coupling match these shaft diameters precisely for a secure fit.
Are coil spring couplings suitable for high-speed applications?
Coil spring couplings can be used in moderate to high-speed applications, but it's essential to check the manufacturer's specified speed rating. Exceeding this limit can lead to premature wear or failure.
