Choose a rodless pneumatic actuator for the required travel, installed length and moving-load geometry. Review guide moments, sealing and stopping energy with the actual air circuit. Long stroke in a compact envelope does not remove the need for rigid support and suitable load guidance. Run representative minimum and maximum loads through full travel at the intended point-of-use pressure. Check smooth motion, carriage/tool deflection, end impacts and position signals. Include long-cycle warming, controlled interruption and restart, documenting support positions, guide alignment and air settings with the result. Submit the intended configuration and any OEM/ODM changes for project-specific feasibility review.

Choose the rodless transmission concept
Mechanically coupled and magnetically coupled rodless cylinders have different operating boundaries. State the intended force, environment and carriage duty. The SMC MY1B reference uses a mechanically jointed arrangement; its characteristics should not be applied automatically to a magnetically coupled alternative.
Assess carriage moments and guidance
Provide payload, overhang and forces applied to the moving table throughout travel. Some rodless cylinders need external guides to carry these loads. Compare the selected guide arrangement and mounting with the actual moment directions rather than inferring bearing capacity from a long carriage surface.
Support the long-stroke structure
A long actuator can deflect or distort if mounted on an unsuitable frame. Define span, intermediate supports and alignment requirements using the selected model's instructions. Installed length should include fittings, end adjustment and service clearances, not only the nominal cylinder-body dimension.
Size speed and end cushioning
Supply travel time, cycle rate and moving mass with valve and tubing information. Large travel can produce substantial end energy. Confirm allowable cushioning or external absorbers and assess controlled stops; raising pressure is not a substitute for selecting adequate flow and energy capacity.
Protect the sealing band and sensing
Describe dust, chips, coolant or sticky contaminants along the stroke. Confirm covers, sealing-band care and sensor access. Position switches must indicate the required machine states, and adjustment should account for carriage stopping behavior rather than simply matching a nominal groove location.
Review air loss and maintenance recovery
Determine what happens to the carriage when pressure is lost, especially on sloped or vertical installations. Identify safe isolation and load support. Obtain sealing, guide and end-stop parts with a procedure for restoring alignment and speed after service, since the entire travel influences reliable operation.

| Review air loss and maintenance recovery | Orientation, pressure-loss behavior, support, seals and post-service checks |
Plan installation and access
Align the actuator and any external guide over the full travel, using supports that do not twist the body. Keep hoses and sensor wiring outside the moving-load envelope. Guard the long swept zone and provide safe isolation and mechanical support before adjustments.
Agree acceptance evidence before ordering
Run representative minimum and maximum loads through full travel at the intended point-of-use pressure. Check smooth motion, carriage/tool deflection, end impacts and position signals. Include long-cycle warming, controlled interruption and restart, documenting support positions, guide alignment and air settings with the result.
Define OEM/ODM engineering boundaries
OEM carriage adapters, covers and approved stroke variants can be reviewed. ODM band sealing, coupling or guide changes require mechanical and endurance testing. The reference image identifies a particular rodless family and does not confer its load ratings or manufacturer authorization on another design.
