Linear motion

Convert rotation into linear travel. A dual-shaft rail guides and carries the load. A belt stage covers long, fast moves. XY, gantry, and screw builds are configured per project.

Function

The motor output is rotation. For linear travel, either a rail constrains the path, or a belt converts revolutions into millimetres.

  • Dual-shaft rail: two round shafts, carriage held by rollers. No motor. Guidance and load only.
  • Belt stage: profile, timing belt, carriage, and motor mount. Travel can be long and speed high. Repeatability grade C is ±0.04 mm.

Use a rail when the slide is pushed by hand. Use a belt stage for powered long travel. For a short stroke and tighter accuracy, a screw can be used and is drawn per project.

Do not hang a gravity load on a vertical belt. If the stage must stand upright, add a brake or a counterweight and check the torque. Order SX674-WR separately for home and limits. S2 in a model name is the number of sensor positions reserved.

Besides a single-axis stage, the mechanism can be XY, gantry, multi-carriage, or a screw combination. The figure shows the layouts. Travel and connectors are fixed per project.

Multi-axis linear stage layouts
Layouts: single axis, dual rail, XY, I-shape, and gantry.
XY linear stage layout
XY layout. Choose a screw or a belt from the load and the accuracy.

How to choose

  1. Does it need a motor? Guidance only: rail. A powered linear axis: belt or screw.
  2. Set the profile width. Light load and a narrow space start at 40B, then 45, 65 (profile width 60), and 80. A larger section carries more.
  3. Set the motor position. External BO when the end has mounting depth. Internal BI when the motor mounts underneath or must be hidden.
  4. Calculate overall length. Overall length = effective travel + end constant. The order must say whether the length is overall or effective.

A belt stage connects directly to the MSP drive. In the software, set the lead as millimetres per revolution. A rail does not change software parameters.

Units are mm. The 65 series profile width is 60. Belt grade C is ±0.04 mm. Motors are 100 / 200 / 400 / 750 W. 206 / 226 is short carriage / long carriage.

Order code

Linear units are not in the configurator default cross. The order must state series, effective travel, short or long carriage, motor, shaft direction, and sensor count. Mark the length as overall or effective.

Do not oil the timing belt. The mounting face should be IT7. A cantilever should not exceed 4 × the body width. XY, gantry, and screw combinations are numbered separately per project.
