What’s the difference between the X-50 and the X-35 (original) rails?
The X # refers to the diameter of the tubes. There’s some confusion that it is the length.
X-50 are 50mm diameter tubes at 6mm wall thickness. X-35 is 35mm diameter tubes at 5mm wall thickness. The thicker the tube, the more rigid and heavy the rails are.
When compared to the X-35 (original) rails, the X-50 comes with a larger Stepper Motor with up to 40% more torque, and a 1616 (vs a 1610 original) Ball Screw that delivers 60% more speed with no change to the motor settings.
The X-50 comes in 2 different sizes: Woodworker (32’), Jorneyman (48")
The X-35 comes in 2 different sizes: Machinist (16"), Woodworker (32")
