LEGO compatible thrust ball bearing

LEGO compatible thrust ball bearing

To rotate an axial load LEGO developed the turn table. For light loads this works great but the friction increases dramatically with heavy loads. This thrust ball bearing uses standard LEGO balls to transform the friction into rotations. This allows the two disks to easily rotate. The balls and an additional rim keep the two disks in place.

A motor can be attached on the inside to power the rotation. Even the smallest LEGO motor is sufficient to easily rotate this 2 kg load. This thrust ball bearing is fully LEGO compatible and even allows studs to be attached to top half. Standard 14.2 mm LEGO balls can be used. The bearing measures 20 studs across and is three bricks high. This should be big enough for even the biggest crane or MOC display.

The 3D data is available from the Autodesk Gallery.

Galaxy Explorer 6000

The LEGO Galaxy Explorer is amongst one of the most popular sets of all times. In 1980 LEGO published the Idea Book 6000 that contained an alternative build for the Galaxy Explorer. The building instructions were sketchy at best. I built the Galaxy Explorer 6000 model for the Moonbase 42 at the Christchurch Brick Show 2015 and I also created an LDD file for it. The building instructions are available here. It has been great fun to re-create this spaceship from my childhood. I hope you enjoy it.
