14 best mechanical constant force springs
Mechanical constant force springs are a type of industrial hardware used in various applications to provide a constant and consistent force over a defined range of motion. These springs are designed to exert a uniform force regardless of the extension or compression of the spring. Here's what you need to know about mechanical constant force springs:
Purpose and Applications:
- Mechanical constant force springs are used when a consistent force is required in applications such as retractable cords, seatbelt retractors, window counterbalances, and more.
- They are often used in situations where it is essential to counteract gravitational or other external forces.
Design:
- These springs are typically made from a flat, spiral-wound strip of steel or other materials.
- The design of constant force springs allows them to exert a nearly constant force throughout their range of motion.
- The force exerted is a function of the material properties, width, thickness, and the number of coils in the spring.
Features:
- Constant force springs offer a linear force output, which means that the force remains constant as the spring is wound or unwound.
- They are often designed to be space-efficient and can be configured in various shapes to fit specific applications.
Applications:
- Constant force springs are commonly used in automotive retractors, such as seatbelt retractors, to ensure a consistent and controlled retraction of the belt.
- They are also used in various industrial equipment, such as cable management systems and medical devices.
Benefits:
- Predictable Performance: These springs offer a predictable and reliable force, making them ideal for applications where consistent force is critical.
- Space Efficiency: Constant force springs can be compactly designed to fit within tight spaces.
- Durability: They are known for their durability and ability to withstand extended use.
Limitations:
- Constant force springs may not provide high force levels, and their range of motion is limited by the length of the coiled strip.
- Extreme environmental conditions can affect their performance.
Customization:
- Constant force springs can be customized to meet specific force requirements and design constraints.
- Manufacturers can alter the width, thickness, and material properties to achieve the desired force characteristics.
Manufacturers:
- Various companies specialize in the design and production of constant force springs, including Associated Spring Raymond, Lee Spring, and Vulcan Spring & Mfg.Co., among others.
In summary, mechanical constant force springs are specialized industrial hardware components designed to provide a consistent force throughout their range of motion. They are used in a wide range of applications where maintaining a constant force is essential, offering predictable and reliable performance. These springs are customizable to meet specific force requirements and can be found in various industries, including automotive, aerospace, and medical devices.

Take Control Over Your Thoughts
"You can deliberately plant the good seeds/thoughts of God in your mind. As these thoughts take root and grow, they will help remove the destructive weeds that the Enemy tries to plant in your mind."
Develop an Intimate Relationship with Jesus
"God wants to be known by you, and you can know as much about Him as you have the appetite and desire to know. He invites you not to settle for surface knowledge."
Find Encouragement, Hope & Strength In the Midst of Your Valley
"When you allow Jesus to be your Shepherd, He steps into this stressed-out culture and becomes your replenishing guide. He leads you, watches over you, and gives you rest. Jesus gives you purpose."
Redefine Yourself & Remove Any Guilt and Shame
"Many of you are walking around with a scarlet letter of your own. You are defined by your sin. God changes your identity. The Enemy wants to define you by your scars. Jesus wants to define you by His scars."
Lysa TerKeurst
Louie writes with hope and speaks freedom to our weary hearts that need the victory available to us through Jesus. This book is a treasure you’ll return to again and again. I can’t wait for you to read it and see your life transformed!

The greatest war of our lives centers around the battle of the mind. I am grateful for work like this that floods our spiritual artillery with gospel ammunition. Thank you, Louie G (that’s the rap name I gave him), for giving us the kind of depth and accessibility we need to hold the line for the glory of God in the war zone of our minds.
Sadie Rob and Christian Huff
Don’t Give the Enemy a Seat at Your Table reminds us of the identity that we have in Christ—that every battle He has won we have won also! Louie shows us how God invites us into relationship with Him and gives us a seat at His table, all the while winning the battle of your mind.
Steven Furtick
Louie’s new book, Don’t Give the Enemy a Seat at Your Table, is for anyone who’s been letting the enemy occupy space in their mind. Whether it’s anger, loneliness, insecurity, or shame, it’s time to kick the enemy out of your mind and take back your seat at the table.
