X55 Roller Bearing

   
Well, I've finally tinkered around with a few iterations in order to come up with something robust enough for you to 3D Print yourself! The looser tolerances ensure that your printer will have better luck with this one.

     This is the simplest bearing I've made to date, and foregoes the spherical knuckular flanges which make production difficult. This one features simple and straight rollers. I even included an assembly jig to make assembling it easy. In the past, these rollers were incredibly tedious to put together, but not anymore! 

     So try it out, and tell me what you think.

Required Quantities and Recommended Print Settings (Infill)

(x7) Main Rollers: 0%.

(x7) Spacer Rollers: 0-20%. (Doesn't change print speed too much)

(x2) Concentor Collars: 10-20%. This part needs the strength. 

(x1) Inner Sleeve: 10-20%. I printed at 20%, (supports required*)

(x1) Outer Sleeve: 10-20%. (supports required*) Thicker bottoms and tops will allow you to bring this below 20%. 

(x1) Assembly Jig: 0-20%

*Unless you have adequate overhang printing capability, supports are generally required to accomplish the 90 degree angles and tight corners on this model.
