FAQ ST Torque Limiters
1. What is the maximum speed rating of the ST?
The max rpm depends on the application. It is important that the differential speed is no more
than 5, rpm.
2. When would the springs begin to weaken?
The only factor here would be temperature. A weakening / reduction of the spring force would
take place around degrees Celsius.
3. What material is the ST made of, in regards to tensile strength?
The ST is made of high-strength, hardened steel. A material that has been proven over the
past years.
4. How does the torque limiter behave after being in use for long periods of time? Does it
continue to disengage within the preset range?
Yes. The ST is composed of wear-free components. The axial spring tension is guaranteed to
remain unchanged since the engagement receptacles are located on a plane of reference.
The empty space in the torque module is filled with grease. [Note: Bibby + Autogard have a
grease nipple].
5. Is there a test report involving the precision of re-engagement?
Yes, on the part of the RWTH. The value is roughly +/- 3%.
6. How does the torque limiter behave with heavy shock loads, for example on a crusher
that is filled with different amounts of different materials?
The shock moment must be provided by the customer.
7. How much force must be used to re-engage the plunger on the torque module?
For the series -60, a light hit with a rubber mallet will do the trick. The series can be re-
engaged with a special tool. Alternatively, if there is enough space, a forceful strike with a
hammer will re-engage the module.
8. Are there options for another function system in regards to re-engagement?
We are working on an automatic re-engagement version so that the operator would not have
to manually reset the torque limiter. Conclusion: Automatic re-engagement is coming.
9. How precise is set disengagement torque of the ST?
The tolerance is +/- 5%.
