Linear rail maintenance
MGN12 Rails
Your linear rails use small ball bearings in recirculating tracks.
Balls fell out from dissassembly?
- MGN12 Rails use 3/32" mm ball bearings
- Fill your cartridges to minimize available space. You should *not* overpack the bearings - pack as many as you can to ensure smooth movement, but ensure there is a slight gap available in the track
- Use your best precision to reassemble carriages back on the rails and when taking them off. Printed tools like this can help guide the rail onto the carriage without losing ball bearings. https://www.printables.com/model/790997-mgn12-carriage-holder
Grease: You should ensure your rails are adequately greased. We stock excellent greases here at Luke's Laboratory:
