All Drawbar Springs

Drawbar springs have long steel loops that pass through the centre of the spring and hook around the opposite end, compressing the spring on loading.

This design helps prevent unexpected overloading and fracturing that can occur in standard extension springs by stopping and hold the load at the spring limit. The spring rate indicates the load required to pull out the first 25mm of the spring.

301 Stainless Steel

Mounting hole specifications will be supplied on request. These springs are usually mounted on a drum and the free end attached to a loading force like a counterbalance. Free ID may vary to meet load specification. Load capacity can be increased by using multiple strips in tandem, back to back or laminated. Be sure to leave at least 40mm coiled on the drum at full extension. The spring ID will wrap tightly on the drum so that most applications require no fastening to the drum.
