Incompatible with 3/32 " balls despite this being the standard for MGN12 rails

If you lose any bearing balls in one of these, consider it completely useless. 3/32" bearing balls are too large and will make the rails very hard to move. If you get a defective rail it will miraculously be even worse if you try disassembling it, cleaning and lubing it. Of the seven rails I have, one is so bad that it won't slide even if you hold the assembly by the carriage at a 90 degree angle.

Pros

The linear rail guide offers excellent wear resistance to prevent deformation

Cons

The linear rail guide may be too thick to fit certain types of 3D printers or CNC machines, reducing its compatibility
