Production compensation
Normally we compensate through the spring's unloaded leg position ( ) to be able to
meet the torsion spring requirements.
Fixed parameters
Compensated by
One spring torque, the respective angle of rotation of the
1.
tensioned spring.
One spring torque, the respective angle of rotation of the
2. n,d
tensioned spring and .
Two spring torques, the respective angle of rotation of the
3. ,n,Di
tensioned spring.
Tolerances
Select the quality grade for
the
springs. Our
torsion
torsion springs are usually
manufactured to DIN 2094
Grade 2 as standard. If you
select Grade 1, your torsion
spring is manufactured
according to the smallest
tolerance range, and for
Grade 3 with the largest
tolerance range.

Coiling direction
Please make sure that the torsion
springs are only stressed in the
direction of coil.
Unstressed leg position ( )
Select one of the given leg positions or enter the desired angle
under "Other".
Surface treatment
The disadvantage of later surface treatment for the majority of
torsion springs is that application of a protective coating to the
coils is only possible at extremely high cost on account of the
spring body. Here, the selection of a suitable material should
usually be preferred to later surface treatment. Select a surface
treatment frompage 13 if required.
