Conical Springs·CUSTOMIZATION

Heavy duty conical springs are engineered for applications requiring high load capacity and excellent fatigue resistance. The unique tapered design provides progressive spring characteristics and efficient space utilization. Our heavy-duty conical springs are widely used in industrial equipment, automotive suspension systems, hydraulic applications, and specialized mechanical devices.

The parameters of the conical compression spring

d (spring wire diameter): This parameter describes the diameter of the spring wire.
S (Maximum Diameter of Mandrel) This parameter describes the maximum diameter of the spring shaft in industrial applications.
De (outer diameter of the outsole): the outer diameter of the widest end of the spring.
De (outer diameter of small bottom): the outer diameter of the narrowest end of the spring.
H (minimum aperture): This is the diameter of the minimum space required for the normal operation of the spring.
Lc (compressed length): The theoretical length of the spring when each coil is in contact. For most tower springs, this value is equal to the wire diameter.
L0 (Natural Length): The length of the spring in its natural state after being compressed once.
R Spring stiffness: This parameter represents the load change per unit deformation of the spring. Unit calculation: 1 DaN/mm = 10 N/mm (Newton/mm), tolerance ±15%.
L1 & F1 (length L1 of the spring under load F1): Load F1 and length L1 can be calculated with this formula: F1 = (L0-L1)* R, and then calculate the length L1: L1 = L0-F1/R
