This is a clamp for the P3steel 2.x Y-axis.
Designed for use with IGUS RJZM-01-08 bearings.

The outer diameter is 1mm bigger than the LM8UU standard bearings. That is why the original lasercut clamps don't work and you need modified parts.

It's the next part of a complete series for P3steel parts.
I redesigned every part based on my long time experience with the P3 steel.

Please share your makes!

is this compatible with Igus DryLin® RJ4JP 01-08?

Thanks for the great design! Did you also update the x-carriage to accommodate the IGUS bearing?

I'm looking at replacing all of my LM8UU's with RJZM-01-08's in the hopes of a more reliable and quieter experience. What was your experience doing so?


I don't use the IGUS bearings anymore. They are expensive and hard to handle.
I switched to sinter bronze bearings. Check out my Blog for the MK2 version.

Ah, thanks for the great input! Do you run those bronze bearings on hardened/chrome plated rods? And if so, does that work ok? I had read somewhere that using bronze bushings or even IGUS bushings on smooth rods don't work as well because they require some abrasion in order to deposit their lubrication.

I'm confused. The LM8UU's don't fit in snug with these brackets. They have about a millimeter to move around from top to bottom. Is that supposed to happen? It looks like from your photos that your's are not snug either.Seems like this could cause noise in the y direction?

This is for IGUS bearings and NOT for LM8UU.

I made another type for LM8UU bearings. Use this one.

Wow yep there it is right in the title. Thanks for responding to my idiotic question! Just installed the y axis belt tensioner so at least the afternoon wasn't in vain! Thanks for the awesome remakes.

How much cost the igus ?

Hi Toolson.
Do you have this clamp for P3steel and standard LM8UU?, not for IGUS?
Your design is better than the piece that comes by default with p3steel.

Thanks in advance.

Thank you, ;-)
It is printing them now

Hi, do you have a version of this clamp and your X carriage design that would be suitable for Igus Drylin RJ4JP-01-08 bearings?

You should use this type of bearing only in a pressfit seat. Otherwise the tolerance is not defined.
You cannot make a pressfit with a printed part.
