Attaching a load to a Uhing traverse drive

Uhing traverse drives are friction drives. The rolling ring bearings are under pressure and in direct contact with the surface of the drive shaft. If you attach a load, then you are increasing this pressure on the bearings and as a result, the bearings...

Is this you?

It's taken me 10 years to become somewhat proficient at being able to match Uhing linear drives to applications for which they will be an ideal fit. I'm no genius. But every day I speak with folks who seem to think they are. If someone asked me what is...

Are you changing the length of travel on your Uhing traverse drive?

If you are, then depending on how you are changing travel length, you need to be aware of shaft vibration or you might run into some problems. In the photo below, the traverse assembly was built for a maximum travel of 28 inches.

It doesn’t always make “sensor”

This here is a pretty cool picture of a Uhing traverse winding set up to which sensors and electronics have been added. In this case, the sensors monitor traverse linear speed, spool rotational speed and line feed speed.

One size does NOT fit all

I often get phone calls and emails from people saying "I'd like a quote on (insert Uhing rolling ring traverse drive model number)." I can approach these requests in two ways: 1) I can quote as requested and probably make a fast sale. 2) Or I can do what...

Using adjustable pitch to an advantage

Today we completed a Uhing assembly with the "S" option. This option enables the Uhing traverse to move at a set pitch in one direction, and then at the same or a different set pitch after reversal. In this case, the customer needed the drive to move...

Repairs to Uhing rolling ring drives

I get calls all the time from folks who want to repair their Uhing traverse drive. They want a parts list and they want to order the parts and do the repairs at their facility. Regardless of mechanical aptitude, repairing a Uhing drive is tricky. There...

It’s a friction drive

That means that the bearings put a significant "bite" on the shaft. Anything you do in your set up to interfere with that "bite" will cause problems for you. You can't lessen or increase the pressure of the bearings against the shaft. If you use oil or...

Accident waiting to happen

Was in Milwaukee last week seeing customers. Worked with the Amacoil rep out there who is very competent and a good guy. We saw one guy who had installed a new Uhing drive assembly with the L4 linear bearing slide. This load carrier mounts across the...
