Excavator Turntable Bearing

thingiverse

This is a turntable bearing that i designed when i was building a model excavator. i figured that the community could use it. This is printed in four parts. To fill all of he bearing races you either need to purchase or print the enclosed file of bearings. You will need 79 balls to completely fill all the races without to large of gaps. In the photos I didn't remove all the mates in solid works I just removed one so I could show the inside of the parts. there is a updated version that takes the same balls but just has 5mm holes for attaching it to parts. the updated version is also almost twice as thick for more strength. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: No Resolution: .005 Infill: max Notes: Best results came from printing flat side down and using ABS. this can be printed using any plastic or metal though.
