If you are designing a product that requires any sort of smart-motion precision, spring parts that apply constant force or constant resistance are key mechanical design elements to consider. Two of ...

1. Constant Force Spring 2. Constant Torque Spring 3. Constant Force Spring for Carbon Brush 4. Power Spring and Prestressed Power Spring 5. Variable Force Spring 6. Spring-Strip Tube 7. Assembly and ...

John Evans’ Sons is the international leader in design and manufacturing of constant force springs, constant force spring assemblies and pusher springs (variable force). Our vibration isolators are ...

Compliant constant‐force mechanisms represent an innovative class of devices engineered to provide a near‐invariable output force over a defined range of motion. By exploiting the elastic deformation ...

A force of 3 N is applied to a spring. The spring stretches reversibly by 0.15 m - the fact that the string stretches reversibly means that it will go back to its normal shape after the force has been ...
