Zaber's linear stages can produce enough force to cause personal injury. Be careful to not get body parts caught between the moving carriage and the end plates of the stage. Make sure that no loose clothing gets caught in the rotating lead screw.
Teflon-coated (black) lead screws are not designed to be greased. Normally no lubrication is required over the lifetime of the device. If a squeaking sound develops in the lead screw, Super Lube oil with PTFE (Product number #51004) can be applied. Apply a very thin bead over 80% of the contact surface of the lead screw and run the stage slowly from end to end. Wipe off any excess.
