HIWIN linear guide too tight

[IQChallenged]

I have some HIWIN linear guides that I bought on eBay. One of them is very tight and hard to push (by hand) while the other three are far easier to push. Is there any way to adjust these things?

Usually they are tight as standard but the more pressure you put on them, the better they glide. Try to load it with your body weight and slide it. It should run smoothly then.
This is not specific for Hiwin, all guide brands are similar.

No. I'm talking about a level of resistance that 2x the rest of them. Surely there must be a prescribed tension (range).

Check the part numbers to the HiWin site.....generally you can buy them with different preloads.....

Check if it has adjustable preload.
