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.

Cadbury Energy Chocolate Scam

Many products are being sold that are suppose to increase your energy. Unless your food is completely indigestible, this will always be true. Food by definition has calories which provide you with energy. But food manufactures have moved on and this trivial definition of energy is rarely used. These days energy food typically contains Caffeine. In particular energy drinks, such as Red Bull, Mother and V contain a considerable dose.
