How do Igus bearing material compare to Nylatron GS which is a molybdenum disulphide impregnated nylon from Quadrant?

No matter how you push it.....nothing rolls as smooth as a ball.

Great presentation. I've been prototyping our new product with igus DryLin rails/blocks and love them. I am interested in making custom extruded profiles for our production version (as you descibed here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SLXX4kHNp5s.html&t=21m00s) that work with DryLin pillow blocks. Can you recommend an aluminum extruder in the US to do this? Or guidelines to follow for best performance with your bearings (like making the profiles hardcoat anodized, etc.)? Thanks!

Accuracy compared to hiwin square rails and blocks? Also curious if you make a hiwin style replacement block like hgh20,25,30??. Many of the aftermarket applications are limited to distance apart bearing blocks can sit. If 4 Drylin style blocks were used the tables would have the capability to travel beyond one of 3 blocks and allow for 4” more X axis travel where bearing blocks would be limited to two and therefore be subject to axial loads that may exceed their specifications. Having the option to use drylin or at least adding two additional drylin blocks atop existing bearing blocks would be a desirable option even despite mixing bearing blocks the benefit would certainly increase overall performance and prevent limitation of table travels in aftermarket (hobby) applications.

Plastic Bearing do run down and need to be replaced to often ! already tested on a new Prusa MK2 and after 3 weeks printing the Igus Bearing were replaced to the original Steel Bearings because of worn out and wiggling on a m8 Rod

You did something wrong then. I have over 300 hours on an MK2S with the RJZM-02-08 in place of all the OEM steel bearings.

Can plastic shaft be used instead of metal? This can reduce weight.

chia ming Chen No, in fact I can't think of any common application or that would be just too specific. The load apply on a plastic shaft would just make a flexion which isn't the best thing.

You could use carbon fiber

Nice, I'm going to try your parts in windows, and doors.. That's where the most wear and tear happens and meal bearings just isn't the best solution I think.

thank you this is a super useful tool for calculations and simulations. we will surely be emailing to you.

How would these hold up in 3D printing applications? I see advantages (self lubricating, resistant to dirt, vibration dampening and dual rotation) but wonder if this application would tax them as precision (= or - .001mm) and speed (200-300mm/s) are also needed.

Interesting that I've not seen igus rail solutions used in 3D printing yet. I've seen HiWin, and the LM8UU style bearings being replaced with igus bearings. I actually ordered some like those earlier, but I'm getting curious.
