## Questions & Answers

**Q: What size is the bolt hole?**
A: 5/16” threaded bolt with a lock washer has worked very well for me.

**Q: What size is the bolt hole?**
A: It's a 608 bearing, so the inner diameter is 8mm. http://www.gizmology.net/bearings.htm (It mounts on an M4 bolt)

**Q: I would like to know the weight that these pulleys support**
A: I don't know. I used them for my son's robotics team

**Q: Is there a load capacity on these if you are using them as a pulley?**
A: There probably is, the Plastic outer would be the limiting factor as excessive weight would make the cable or rope cut into the plastic.
