uxcell F3-8M Thrust Ball Bearings 3mm x 8mm x 3.5mm Chrome Steel Single Direction 10pcs

When I use thrust ball bearings, I can thrust all day with no Z wobble.... what's in your Z Axis?

These bearings make the tuners on an R-Trem far more precise and comfortable to use. I removed the two washers on each tuner and replaced them with one of these. Big difference. Note there is just BARELY enough screw there to make this work.

I'm using these thrust bearings for a robotic project that I'm working on and they feel great. They glide smoothly and are all consistent. The measurements are spot-on (I checked with my calipers) and I don't have any complaints. Would recommend!

I bought these (the 3x8x3.5 size) after seeing them mentioned on a guitar forum for fixing rough tuning on Stinberger-style tremolo systems... and man, are they FANTASTIC! Even on my cheapo knockoff trem, they give silky-smooth tuning without slipping. I can't recommend them enough!

Work as described. Nicely individually packaged

Product delivered was as described. Used them to fix two swivel office chairs.

I have a machine that has adjustments made by a wing nut and a spring. I wanted to reduce the friction between the wing nut and the plate it pushes against. I bought these, not really expecting that they'd be as nice as the 3-6" versions I use on other machines. I was surprised by the quality when I took them out of the package. I installed them and they were smooth. As I ran the machine the wing nuts were actually TOO SMOOTH. Now they were moving and the machine fell out of calibration! I had to remove them, however I have another machine under design and were going to make my own "lazy Susan"; now I will use these.

I noticed the bed on the ender 5 plus seemed heavy. Stepper motors are not designed to support much axial weight capacity so these were used these to carry the weight for the Z stepper motors.
