BushingsA Technic bushing is a small cylindrical element with a cross hole in the center. When placed on a cross axle it acts to limit the lateral movement of the axle, acting as a stop bush. The 1/2 bushing, introduced in 1981 included teeth on one face, allowing it to fit with the other toothed elements. As the toothed system of elements was phased out a smooth-faced version was introduced.
