Well made and seem to be solid enough for the task. These have c clips holding the cross pins. Others don't. They are quite weak. Working well so far.

One of the joints was messed up in the first set that I ordered. The joint would only swing freely in one of the directions. Amazon replaced that set, but that adds a lot of unnecessary hassle. I ordered several different sizes of these and only one joint out of ten was broken. The rest are fairly solid and appear to work fine, so I'm ok but the quality control could still use some improvement.

This product connected an 8mm threaded rod to an 8mm pillow block bearing.

Works as it should, 4 stars because the allen screws to tighten it get rounded off easy

They seem sturdy enough. They're not solid stainless steel but they're not a cheap metal. The things I like most about these is they're precise at 8mm with no wiggle or friction. The boar is 8mm straight to the joint, so if you needed to restrict motion you can push your rod or shaft up flush to the joint bar. Also another nice thing is the joint on these aren't some metal dowel smashed in but rather a pin with snaprings keeping in place so if you so needed you could take it apart and use as a y joint. I personally used these for a motorized actuator and this is the joint that goes on the back of the push rod and front of the rotating arm and it keeps the rods in place well without any wiggle or getting loose, just be sure to file or drill a couple of dimples for the set screws on your rod and it'll hold it tight and no rotating or jiggle.

Artikel ok, leider im Modell sehr laut. Trotz ausgerichtete Wellen.
