Airtac JSID Double Rod Cylinder JSID40X125
The AirTAC JSID Double Rod Cylinder JSID40X125 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 125mm 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 JSID40X125
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm bore double-rod actuator uses a G1/4 port and a 16 mm rod to ensure perfectly symmetric force. The twin-rod architecture creates an equal pressure area on both faces, meaning push and pull outputs are identical. This design naturally resists torsion and provides a stable, anti-rotation load path for demanding mechanics.
Built to JIS standards with an extruded hard-anodized aluminium profile barrel, it is noticeably shorter than a same-bore ISO 15552 cylinder. Note that this specific SKU lacks a magnet and cannot accept CMSE/DMSE sensors; choose the -S variant for position detection.

Where the Airtac JSID Double Rod Cylinder JSID40X125 Is Used
Twin-Tool Transfer
Drives two opposing pickers simultaneously from one piston, keeping cycle times perfectly synchronized without adding a second valve.
Anti-Rotation Press
Uses the symmetric dual-rod structure to press bearings flat without twisting, eliminating the need for a separate linear guide.
Symmetric Divertor
Pushes product from either side of a belt with identical 528 N force, ensuring consistent sorting regardless of travel direction.
Is the Airtac JSID Double Rod Cylinder JSID40X125 the Right Cylinder?
When sizing this double-acting actuator, the equal-both-ways force is 528 N at 0.5 MPa. If you need less power, the neighbouring 32 mm bore provides 345 N, while stepping up to the 50 mm bore yields 825 N. Choose this twin-rod configuration when your mechanism demands anti-rotation guidance, symmetric load distribution, or needs to drive two tools simultaneously from one piston. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. For this 125 mm stroke, ensure external guide rails are used to prevent side-load binding. Remember that a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 JSID40X125 FAQ
Because the 16 mm rod passes through both covers, force is equal in both directions: 528 N at 0.5 MPa and 739 N at 0.7 MPa. The theoretical maximum is 108 kgf at 1.0 MPa. It features a G1/4 port, M14x1.5 rod thread, and adjustable 20.5 mm air cushions at each end.
No, this specific SKU does not have a magnet and cannot accept CMSE or DMSE switches. You must order the -S variant to enable position sensing. The air cushions only decelerate the piston near the end caps; they do not hold the load, so use a pilot-operated check valve for vertical applications.
