Retractors

Manual-Return Hanging Retractors

Lift your tool until the cable retracts into the housing.

Strip Springs

Constant-Force Retractors

For controlled extension and retraction, these retractors provide the same amount of force no matter how far you extend them. The flexible attachment cable allows a wider range of movement than standard constant-force springs.

Constant-Force Springs

No matter how far you extend them, these springs pull back with the same amount of force.

Clip-On Constant-Force Springs

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.

Variable-Force Springs

Unlike constant-force springs, the farther you pull these, the harder they are to pull. Use them for applications where the load becomes lighter as the spring contracts, such as in automated dispensing machines.

Extension Springs

Mil. Spec. Extension Springs with Loop Ends

These steel springs meet MS 24586 and come with a traceable lot number and material test report.

Extension Springs with Loop Ends

Use these steel springs in noncorrosive environments.

Garter Springs

With ends that are connected to form a circle, these garter springs exert strong radial (towards the center) forces from all directions to maintain pressure on shafts or in seals.

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.

Spring Assortments

Extension Spring Assortments

The more you extend these springs, the greater the force the springs will exert to pull the two points back together. They're commonly used to tension cable, return an air cylinder to its starting point, and hold a door closed.

Elongated-Hook Extension Spring Assortments

The springs in these assortments have deep hooks that are less likely to slip off compared to standard extension springs.

Extension and Compression Spring Assortments

These assortments include springs that pull and springs that push.

Extension, Compression, and
Torsion Spring Assortments

Keep a collection of three of the most common types of springs on hand.
