    Can I use only 1 bearing blocks per axis?

    Hi all!

    My current machine's Y-axis saddle length is 137.5mm. The new linear guideway I'm installing on my machine comes with 124mm bearing blocks.
    The load-bearing specs of the new bearing block are more than enough to support the weight on my current Y-axis.
    Can I use only 1 bearing block to mount the saddle on?

    What size rails? A block that long is probably meant to be the only block on the rail, and may have two tracks of bearings per race, or just a much longer loop.

    Yes, you are right on. 2 tracks of rollers per side. It's the Hiwin roller type series(RG series).
    I'll be installing the 25mm and 35mm rails. 35mms on the Y-axis.
