    Hi every body,

    1) For rod ends, I saw that everybody using this one for connection.

    But the angle of this is limited. I am already using these rod end bearings in 3 dof with out any problem. Can I use this one in 2 dof motor to upper frame connection ? Any comments.

    2) Also again every body uses this one for center support point.

    I want to use same bearing (image-2) as center support u-joint. Is there any drawbacks or else ?

    Thanks for support.

    Tie rod ends. like you have linked or these more common ones, will work fine for the rod ends: https://www.aliexpress.com/item/1559309095.html

    But they are not good for the center support, as they allow unwanted lateral rotation, a universal joint as pictured does not allow lateral rotation, hence why members use them.

    Thank you for fast reply. Your sended rod end is 90 degrees. Mine is 180 degrees. I think it is ok for rod ends.
