A system for virtual reality (VR) motion control includes a multi-dimensional motion platform and a thrust universal spherical plain bearing. The VR motion control method includes: setting parameters; calibrating a device; obtaining parameters; receiving a head-mounted display device tracking packet and/or an action control packet; determining whether a real-time angle difference is greater than a set dead zone angle; and calculating a difference between a current angle of a head-mounted display device and a current status of the multi-dimensional motion platform, and feeding the difference into an action control system of the multi-dimensional motion platform, to eliminate the difference. The multi-dimensional motion platform uses single-point bearing or single-point lifting bearing and lever traction-type transmission, thereby realizing functions of swinging and rotating in all directions. The thrust universal spherical plain bearing integrates a common thrust universal spherical plain bearing with a plane thrust bearing.
