Bal Spring - Mechanical Connecting Springs

The Bal Spring canted coil spring exhibits a unique deflection and force behavior when it’s compressed. Unlike typical spring technologies, our spring exerts a near-constant force across the working deflection range, and its forces remain consistent – even in wide temperature ranges. It resists compression set, and its individual coils compensate for misalignment, tolerance variations, and mating surface irregularities. By adjusting the spring groove, spring size, wire diameter and other characteristics, we can precisely control the force it takes to latch, lock, hold, connect, and disconnect. Spring forces can be precisely controlled from less than .5 lb. to >10,000 lb.

Our Bal Spring canted coil springs are available in a range of non-welded lengths (for simple or complex groove configurations), and in welded rings from 0.020 in. (.51 mm) ID. Since every spring is designed to meet the unique requirements of your application, we don’t stock a “standard” size and type. But we do maintain a database of commonly-requested diameters and cross-sections, which can serve as a baseline for streamlined customization.

Our Bal Spring canted coil spring can be designed with coils that deflect in an axial or radial orientation. This makes it possible to optimize the direction of the force in your design, ensuring effective, long-term service. For housing or piston mounted designs, a radial spring orientation is typically recommended. Axial springs are often specified for face mounted installations.
