Drag to rearrange

With the rail still on the absorbent paper towels, carefully and slowly move the carriage from one end of the rail to the other

Both carriages should move smoothly over the entire length of the rail

Small changes in resistance are normal, but the carriage becoming very hard to push, or binding completely are not

Repeat the previous test whilst applying a small amount of force downwards on the carriage

The carriage will likely travel more smoothly when applying a downwards force, this is normal

Repeat the process to check the second carriage on the rail

If the carriage does not move smoothly, or binds completely, refer to the Linear Rail Troubleshooting Guide
