Components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT) are provided. In one embodiment, a CVT has a number of spherical planets in contact with an idler assembly. Various idler assemblies can be used to facilitate to improve durability, fatigue life, and efficiency of a CVT. In one embodiment, the idler assembly has two rolling elements having contact surfaces that are angled with respect to a longitudinal axis of the CVT. In some embodiments, a bearing is operably coupled between the first and second rolling elements. The bearing is configured to balance axial force between the first and second rolling elements. In one embodiment, the bearing is a ball bearing. In another embodiment, the bearing is an angular contact bearing. In yet other embodiments, needle roller bearings are employed.
An idler assembly for a continuously variable transmission (CVT) having a plurality of tiltable traction planet assemblies arranged about a longitudinal axis, each traction planet assembly operably coupled to a carrier having a plurality of radially offset guide slots, the idler assembly comprising:
A continuously variable transmission (CVT) comprising:
