Featuring a unique tapered asymmetrical design, it effectively saves installation space and provides progressive elastic feedback, ensuring stable pressure control within confined or complex mechanisms.

Manufactured using a variable-diameter coiling process, the primary advantage of this spring is the "nesting" capability, where coils fit inside one another when fully compressed, dramatically reducing the solid height. Its conical geometry not only provides superior centering stability to prevent lateral buckling but also delivers an increasing support force as compression progresses, making it ideal for space-constrained applications requiring precision force feedback.
