## Questions & Answers

**Q: Is there a data sheet for these?  i want to know the slip torque for model csk8p.**
A: No, but it is pretty solid and it can take at least 25 foot pounds without issue. I haven't taken it beyond that.

**Q: Maximum torque?**
A: To many variable applications, and I didn't test to failure, use mfg spec

**Q: Has anybody successfully used this in a tongsheng tsdz2 bike motor?**
A: I am not familiar with the motor you are referring to. I used it for a different application and it worked as expected from a one way mechanical clutch.
