Constant Force Springs

Constant Force Springs are manufactured from flat strip material and spooled to a specific curvature matching the needed pull force. There is practically no limit on extension speed and acceleration. The springs can be fitted in a number of ways and extended partly or completely.

Applications for constant force springs include window balancers, counter balances, and point-of-purchase shelving and displays.
