Spring formed in low temperature, such as the cold formed coil compression spring and the cold formed coil extension spring as called by its forming method.
Combination of Multiple springs to obtain the required characteristics. (Springs may be combined in a serial or parallel way. A combination spring comprising two springs is called serial double spring or parallel double spring.)
Composite Resin Spring
Spring made of composite rresin materials, as called by its material.
Spring subjected mainly to a compressive force, in the narrow sense, helical compression spring.
Constant Force Spring
Spring that indicates constant load or torque despite of the deflection change.
Constant Rate Spring
Spring deflection of which is linear to the load applied.
Motion of spring ends or arms under the application or removal of an external load (P)
E-Type Retaining Ring
Retaining ring shaped like letter "E" for on-shaft-use.
Maximum stress to which a material may be subjected without permanent set.
Fixturing a spring at elevated temperature to minimize loss of load at operating temperature.
The spiral form (open or closed) of compression, extension, and torsion springs.
Open loops or ends of extension springs.
Hot Formed Spring
Spring formed in low temperature, such as the cold formed coil compression spring and the cold formed coil extension spring, as called by its forming method.
The heat setting.
Hydrogen absorbed in electroplating or pickling of carbon steels, tending to make the spring material brittle and susceptible to cracking and failure, particularly under sustained loads.
Spring using the elasticity of gas or liquid, as called by its material.
The mechanical energy loss that always occurs under cyclic loading and unloading of a spring, proportional to the area between the loading and unloading load-deflection curves within the elastic range of a spring.
Initial Tension (P)
The force that tends to keep the coils of an extension spring closed and which must be overcome before the coils start to open.
The force applied to a spring that caused a deflection (F).
Generic term for washers for locking using the spring action.
Coil-like wire shapes at the ends of extension springs that provide for attachment and force application.
