A constant velocity drive (32) includes a drive ring (38) and a driven ring (44) positioned around the drive ring (38). Drive links (46) extend from the drive ring (38) to the driven ring (44) to transfer torque applied at the drive ring (38) to the driven ring (44). Elastomeric bearings (54) are positioned at the driven ring (44) to transfer torque from a drive link of the plurality of drive links (46) to the driven ring (44). Each elastomeric bearing (54) includes both spherical bearing elements (62) and planar bearing elements (64) to allow for tilt of an axis of rotation of the driven ring (44) with respect to an axis of rotation of the drive ring (38) while ensuring a constant rotational velocity of the driven ring (44) with respect to the rotational velocity of the drive ring (38).
