I made a 3D printer that uses these bearing! You can find it here: • The Mulbot - 3D Printed Printer
Four Row Linear Bearing Rail
This is a 3D printed square rail linear ball bearing that utilizes four rows of standard .177 cal BB's. This is a similar bearing the two groove bearing rail I have already posted but this bearing uses four rows of BB’s instead of two. This allows for far greater load capabilities and heaver preloads as the balls are easier to recirculate with this design because each bearing is only making contact with the rail at one point. There is also less slop as the two rows on each side are trapping the rail.
Capacity
I’ll post a video on my YouTube channel once I test their load capability but it it can handle my 185 lbs and still slide freely no problem. I wouldn’t be surprised if it could handle 500-1000 lbs. I plan on finding out shortly.
