    Default Linear bearings for CNC router?

    I have Magnum Phoenix CNC router that I got six years ago and replaced its electronics with new ones. Now, I found out that the machine needs new linear bearings. The old bearings are made of white plastic shaped like a tube. The shafts are 1 inch or 25mm. Is it possible to replace the bearings with the ones from: LK2540 25mm Ball Bushing 25x35x40 Linear Motion Bearings ? It's hard for me to measure the old bearings so that I can get new correct-sized bearings.

    1" is not 25mm, and bearings for either size would not be interchangeable.

    If the original bearings were plastic, than there's a good chance that ball bearings may wear grooves into the shafts.

    Igus has a large range of plastic bearings that may work for you.

    I checked the web site that you referred me to and I found out that they have many different kinds of plastic sleeve bearings! Which ones? The old ones are white.

    They don't have to be white, they could be any color, they most likely where made of Delrin, the IGUS material is much better than Delrin, for bushings like this
