Mount these shafts to a support rail to get more support for heavy loads. The shafts have tapped holes along their length and can be mounted to a rail with screws. The thread size and distance between the mounting holes on the shaft must match those on the support rail.
Use linear shafts to support parts that move in a straight line, such as linear ball bearings or sleeve bearings.
