What is the maximum shaft rotation speed for the model RG drive?

I spray my machinery with silicone lubricant. Is this recommended for the Uhing drive?

Does anyone ever specify a maximum pitch that is larger or smaller than the maximum diameter of the wire being spooled?

When I received my Amacoil quotation for a Uhing drive assembly, I noticed a technical specification labeled "gear ratio." What is this?

What is the "L" dimension in a Uhing drive?

Rather than have Amacoil build a linear slide load carrier, can I use one of my own design?

When do I need a linear slide load carrier?

What is the difference between a V-cam and a slowdown cam?

When I reverse my drive shaft my Uhing drive stalls. Why?

Is it OK to install a Uhing assembly without having the mounting surface of the drive facing upwards?

I am considering a Uhing RS linear drive for a CMM application. How can I compensate for the accumulated difference in linear travel?

At the end of a stroke, my Uhing traverse starts to "skip." Why is it doing this?

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?

I frequently use spools of varying widths on the same winding system. Re-setting the traverse end stops every time I switch spools takes too much time. Is there any way to avoid this step?

Can I change the linear pitch of the RS drive head without sending the drive to Amacoil?

We manufacture and distribute several gauges of electrical wire. Any way around having to design a separate spooling system for each wire gauge?

What is the difference between linear pitch and linear speed?

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?

How does the free movement lever work?

In simple terms, how does a rolling ring system reduce my spooling set-up costs?

What is the GS Guide System?

Any tips for setting up a flat ribbon winding operation?

Would I ever use a fixed pitch Model RS linear drive for a spooling application?

Can I make a rolling ring bearing by machining a ball bearing?

My cutting application is set-up in a very dirty environment. Do I need to fabricate a bellows assembly to protect the Uhing unit?

Regarding maintenance of rolling ring linear drives, what exactly does Amacoil mean by "light, periodic lubrication"?
