My payload is a long rod with a spray nozzle fixture at the end. It's too heavy to mount to the drive nut, and I have very little vertical space above the traverse to add a linear slide. What can I do?
Is there any space behind the traverse? If so, you can mount an Amacoil L4 linear slide to the back of your drive nut. The L4 adds only about 1.0 mm in vertical height to your drive assembly, yet completely removes the load from the nut. All radial forces and moments of torque created by overhung or off-center loads are directed away from the drive nut and assembly, and you are assured your system is protected from torque-induced damage.
