About the Airtac SAID40 Double Rod Cylinder SAID40AX160S
The AirTAC SAID40X160-S is a double-acting, double-rod profile cylinder conforming to ISO 15552 dimensions. Equipped with a magnet for position sensing, it pushes and pulls with identical force, yielding 528N in both directions at 0.5MPa. A rod protrudes from both end covers, allowing you to drive a primary workpiece on the front while mounting a cam or position flag on the rear for dual-side guidance.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance over standard carbon steel. It uses PT tapered port threads (G1/4) and includes adjustable air cushions at both ends to decelerate the piston smoothly. The extruded aluminum barrel integrates sensor grooves on both sides, fully compatible with AirTAC CMSE reed and DMSE solid-state switches.

Where the Airtac SAID40 Double Rod Cylinder SAID40AX160S Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, preventing speed variations common to single-rod designs where annulus areas differ.
Anti-Rotation Slides
The twin-rod architecture keeps guided slides perfectly aligned without twisting, ensuring precise linear movement under offset loads.
Dual-Side Actuation
Mount the primary tool on the front rod and a secondary cam or limit flag on the rear rod to trigger external sensors in compact spaces.
Is the Airtac SAID40 Double Rod Cylinder SAID40AX160S the Right Cylinder?
Select this 40mm bore when an application demands equal extend and retract forces alongside anti-rotation stability. It provides 528N each way at 0.5MPa; step down to a 32mm bore for lighter 345N loads, or up to a 50mm bore if you need 825N. The double-rod design is preferred over a single-rod SAI when you need to drive twin stations or prevent a load from twisting.
Remember that the adjustable cushions only decelerate the piston near stroke end; they do not hold a load. If air pressure drops, the cylinder drifts, so use an external rod lock or a SAIL/BSAID model for true position holding. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement matching the 40mm bore, 160mm stroke, PT port, and mounting accessories.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID40 Double Rod Cylinder SAID40AX160S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. It delivers 528N at 0.5MPa, 739N at 0.7MPa, and 950N at 0.9MPa for both extend and retract strokes.
Yes. The SAID40X160-S is dimensionally interchangeable per ISO 15552. It shares the standard 40mm bore footprint and PT port spacing, making it a direct drop-in replacement for other ISO 15552 double-rod cylinders.
