The working load, safety factor, and rated life of the linear bearing were calculated and analyzed, and the strength of the slider, guide rail, and connecting pieces of the linear bearing was checked. The calculation results show that the selected linear bearing type is reasonable, the safety factor meets relevant regulations, the strength of the slider and guide rail of the linear bearing meets the requirements, and the strength of the connecting bolts between the slider and the slide table meets the use requirements.

Linear bearing is one of the components on the suspension frame with high workload and high safety requirements. Its performance directly determines whether the train can operate safely and smoothly through the curve. The selection work mainly needs to consider several aspects such as vehicle load, linear bearing safety factor, structural dimensions, maintainability, etc.
