## Questions & Answers

**Q: What is the maximum diameter size pipe this can roll on.  Thank you.**
A: The groove fits a 7/16" rod at maximum (I'm guessing the groove has a 12mm diameter). Once you're at 1/2" the rod won't sit all the way into the groove.

**Q: What are the ratings for this bearing? i'm looking for static and dynamic load ratings, as well as the rpm rating.**
A: Well made with approximately 1/2" diameter convex surface, don't know the ratings but good quality suggest 500# max load and could handle high rpm with the tolerances used.

**Q: i see that the bearing is made of stainless steel how about the roller?**
A: Both of  Pulley Bearings  and  roller are made of  stainless steel

## Customer Reviews

### ⭐⭐⭐⭐⭐ Made our zipline scary fast!
*by W***W on October 21, 2022*

Bought these to replace some bad bearings on a used zipline trolley. After mounting them, the zipline got dangerously fast. So much so that I had to drop the upper mount by about 3 feet. It's still plenty fast but not "Panic drag your feet along the brush and stumps before smashing through the spring and into the tree" fast. Now it's "daughter's feet shoot up in the air when she hits the spring and freaks out my wife" fast. Perfection.

### ⭐ Fraude
