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.
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.
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.
