Airtac JSID Double Rod Cylinder JSID40X700S
The AirTAC JSID Double Rod Cylinder JSID40X700S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 700mm stroke, G1/4 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSID Double Rod Cylinder JSID40X700S
Delivering 528 N of thrust in both directions at 0.5 MPa, this double-acting JIS profile cylinder uses a twin-rod piston to provide perfectly symmetric output. Because the rod exits both covers, the effective area is identical on extension and retraction, eliminating force mismatch. The hard-anodized aluminum barrel keeps the overall body shorter than an equivalent ISO 15552 unit, and the G1/4 porting matches the 40 mm bore standard.
With the built-in magnet, this -S SKU accepts CMSE or DMSE sensors directly in the side grooves for end-of-stroke detection. A 700 mm stroke demands external load guidance to prevent rod bending, and note that the adjustable cushions only decelerate the piston; an external rod lock is required to hold a load on air loss.

Where the Airtac JSID Double Rod Cylinder JSID40X700S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from one piston, ensuring perfectly synchronized part handling without adding a second cylinder.
Anti-Rotation Web Guide
Uses the dual rods to resist twisting forces during long 700 mm traverses, keeping film or foil web guiding brackets from skewing.
Symmetric Lift Fixture
Balances vertical lifting loads equally across both rod ends, preventing cantilever stress on the piston during mid-stroke positioning.
Is the Airtac JSID Double Rod Cylinder JSID40X700S the Right Cylinder?
This 40 mm bore generates 528 N each way at 0.5 MPa. If you need less power, the 32 mm bore provides 345 N both ways; for heavier duty, the 50 mm bore offers 825 N. A double-rod design is the right call when you need anti-rotation stability, symmetric load paths, or a rear rod end to mount a sensor cam. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S suffix ensures you have the magnet for CMSE/DMSE switches. Because the stroke is 700 mm, you must use external guides to absorb side loads and prevent rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ 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 Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSID Double Rod Cylinder JSID40X700S FAQ
Force is equal in both directions due to the double rod: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a theoretical max of 108 kgf at 1.0 MPa. The air port size is G1/4.
No, the adjustable air cushions only decelerate the piston near the stroke ends and do not act as a brake. For load holding on air loss, you must install an external rod lock or a pilot-operated check valve.
