    Default Linear Rails

    Are linear rails and carriage blocks an interchangeable industry standard? Meaning if I purchase a cheap carriage of the same size to add on to CNCRP's rails would there be potential compatibility issues? Could I buy a third party rail to extend a machine?

    They are not standard, though some brands may be compatible. You would have to check manufacturers specs. Profiles and mounting holes will differ between brands. Automation Overstock produces rails and blocks that work with an older Hiwin profile, but I don’t know of other examples of cross compatibility.

    Actually, they are interchangeable with current Hiwin HG series.

    I think mounting hole locations are somewhat standard, but nothing else usually is.

    Hi Infamous - Its usual not to mix cars and rails from different makers. They are made to an industry std but the std is for overall dimensions and hole spacing and such. So for instance if you use a hiwin 20mm combo you can replace it with a PMI combo. But I've found the actual race height to be different and the shape of the area around the race to be different so WON car seals won't go on HIwin rails or others. so expect some differences.
