So much better than the original ones. My zip line is up and running again.

Good size but are u groove not v groove like advertised

These salvaged our zip line, which has been neglected by the kids because it no longer zipped. The new bearings where a perfect fit, and the zip line works perfectly now.

Used these on the mast of a sailboat. Perfect fit. It helped that the dimensions were clearly shown in a photo. Bearings rotate smoothly.

Dislike fact soap was not included
