Linear Guide Rail 2PCS 300mm + 4PCS

Build yourself a cartesian robot with your linear rails. Pick the right size. Use the right servomotor or a stepper motor to control your robot?s movement. Soon you will have your own robotic crane.

When you need a high level of accuracy, you go for a linear rail. Each block has four rows of ball bearings to smoothly glide along the rail. Build your own CNC from scratch.

Got a broken machine with a linear rail. Pick yourself up a new linear rail guide. They can withstand both download and lift-off loads, as well as moment loads. Superior to round shaft guides.

Maximise bearing life by using the two rails and four blocks in parallel. This will ensure that deflection is minimised and that your machine can handle high loads. For when load capacity, stiffness and travel accuracy is important.

Each linear rail comes with pre-drilled holes. Just use M5 bolts to connect to your mounting system. Make sure your mount is level to get the best life out of your rail blocks.
