    Rotor Springs

    Image of Product. Front orientation. Rotor Springs.
    Wind these springs to store power, then release them to create rotary motion—similar to winding a wristwatch. Also known as clock springs and power springs. All are stainless steel for corrosion resistance.

    Constant-Force Strip Springs

    Image of Product. Front orientation. Strip Springs. Constant-Force Strip Springs.
    No matter how far you extend them, these springs pull back with the same amount of force. Compact and tightly coiled, these springs extend to multiple times their length to pull objects in a linear direction. All are stainless steel for corrosion resistance. Please allow for 1 ½ coils on the shaft at full extension to hold the spring in place.

    Variable-Force Strip Springs

    Image of Product. Front orientation. Strip Springs. Variable-Force Strip Springs.
    Compared to constant-force springs, these are easier to pull at first but become harder to pull the farther you extend them. Use them for applications where the load becomes lighter as the spring contracts, such as in automated dispensing machines. All are stainless steel for corrosion resistance. Please allow for 1 ½ coils on the shaft at full extension to hold the spring in place.

    Clip the end onto a flat surface to install—no fasteners needed. Once installed, these springs pull back with the same amount of force no matter how far you extend them. Compact and tightly coiled, they extend to multiple times their length to pull objects in a linear direction. All are stainless steel for corrosion resistance. When using, please allow for 1 ½ extra coils on the shaft at full extension to hold the spring in place.
