An embodiment of the present invention provides a linear module, which includes: the device comprises a motor 10, a first mounting seat 20, a coupler 30, a screw rod 40, a threaded sleeve 50, a second mounting seat 60, a linear guide rail 71, a sliding table 72, a fixed seat 81, a first bearing 82, a supporting seat 83, a second bearing 84 and a flexible ring 85. The motor 10 is mounted on the first mounting seat 20. The motor 10 is provided with a rotating shaft 11. The two ends of the screw 40 are respectively provided with a first fixed shaft 41 and a second fixed shaft 42. The rotation shaft 11 is connected to the first fixed shaft 41 through the coupling 30. The threaded sleeve 50 is threadedly sleeved on the screw rod 40. The linear guide 71 is mounted on the second mount 60. The slide table 72 is slidably disposed on the linear guide 71, and the slide table 72 is connected to the screw 50. The fixing seat 81 is provided with a first through hole 811. The first bearing 82 is mounted on the fixing base 81 through the first through hole 811. The first bearing 82 is sleeved outside the first fixed shaft 41.
