Springs

Constant-Force Springs

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

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.

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.

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.

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.

Lifting and Pulling

Counterbalancers

A spring controls the tension.

Air-Controlled Counterbalancers

Cable tension is controlled by an air regulator for precise, constant tool positioning.

Counterbalancers with Air Hose

Support the weight of your tool with air hose instead of a separate cable.

Bolt-Mount Retractors

Housings have holes for mounting.

Bolt-Mount Retractors with Stem

Drill through the stem to mount.

Shaft-Mount Retractors

Secure to a square arbor.
