    I was looking at some pictures on the Pendlay website and couldn't figure out how the collars attach to the bar.

    Most cheap bars have a socket-head screw at each end, which I assume screws into the bar to secure the collars. What about higher end bars?

    Here are the pictures I was talking about:

    ^^^ Are those ends threaded? If they are, then a cap could just go on the end.
    I see a slot for a snap ring as well. That can't be the only thing holding the collars on? I guess there isn't much axial load to worry about.

    The problem is on your end, Baconator. I see them.


    Those ends are not threaded.

    As far as I know, the retaining ring is the only thing holding the collars to the shaft.

    *waits for Glenn to confirm*

    The higher quality bars almost always use some sort of snap ring design.

    There is no threading on any of the bars. The HD bars have the sleeves held by a shoulder cut into the shaft and a snap ring. The needle bearing models are held in place by half moon washers that fit into a groove in the shaft and are held in place by snap rings. The Eleiko is fastened in a similar matter, and some variation of this system is used on virtually all high-end bars.

    Barbells are just Chuck Norris' stool.

    Did you even take the time to check the results?

    Thanks.

    How long are the needle bearings? Do they cover the entire length of the collars?
