Abstract
The present invention provides a linear module, which includes a casing, and a linear transmission device (20). The casing has an internal cavity, in which the linear transmission device (20) is at least partially disposed, and an output opening (31) which extends along a movement direction of the linear transmission device (20) defined on the case. A sealing band (32) is arranged at the output opening (31). The linear module further includes a first rolling mechanism (50) which is moveable in synchronization with the linear transmission device (20) and is arranged on a side of the sealing band (32) which is away from the internal cavity. The first rolling mechanism (50) is in rolling contact with the sealing band (32). This linear module enables high cleanliness and has good sealing performance, high accuracy and high stability.
