[0002] The roller guide rail for high-speed travel refers to a roller linear guide rail for guiding linear motion.

[0003] The existing linear motion device usually adopts a steel ball bushing bearing structure in which steel balls move along a circulating track repeatedly. However, this structure generates a large noise when running at high speed, and in a dusty environment (such as woodworking machinery, sanding machines, sandblasting machines, etc.), fine dust easily penetrates into the internal track, hinders the circulation of the steel balls, and causes the bearing to fail, which needs to be frequently replaced. In addition, some high-precision roller guide rails adopt a three-point contact structure, but when there is a small straightness or parallelism error in the equipment, the load will be concentrated on individual bearings, shortening the service life of the bearings, and the entire equipment needs to be disassembled for maintenance, which is extremely inconvenient.
