Airtac JSID Double Rod Cylinder JSID40X25S
The AirTAC JSID Double Rod Cylinder JSID40X25S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 25mm 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 JSID40X25S
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm bore double-rod cylinder uses a single piston with a rod exiting each cover to ensure perfectly symmetric output. The twin rods resist torsional twist during rapid strokes, making it ideal for driving opposing tools or mounting a rear sensor cam. Built to JIS standards with an extruded hard-anodized aluminium profile barrel, the unit is noticeably shorter and more compact than a same-bore ISO 15552 cylinder.
Air enters via a G1/4 port, driving the 16 mm rod at speeds of 30-800 mm/s across the 25 mm stroke. The S suffix denotes a built-in piston magnet for direct CMSE or DMSE reed and electronic switches along the side grooves.

Where the Airtac JSID Double Rod Cylinder JSID40X25S Is Used
Symmetric Clamping
Drives two opposing clamps simultaneously from a single piston, ensuring perfectly balanced gripping force on machined parts.
Anti-Rotation Lift
Twin rods prevent torsional twist during vertical elevation, maintaining precise vertical alignment for delicate electronic assembly.
Dual-End Sensing
Uses the rear rod extension as a mechanical cam to trigger external proximity sensors while the front rod performs the primary work.
Is the Airtac JSID Double Rod Cylinder JSID40X25S the Right Cylinder?
Sizing this actuator requires balancing the 528 N equal-both-ways force against your payload. Stepping down to a 32 mm bore yields 345 N, while moving up to a 50 mm bore provides 825 N at 0.5 MPa. Choose this 40 mm double-rod design when your mechanism demands anti-rotation stability, twin tooling operation, or a symmetric load path. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The integrated -S magnet supports CMSE/DMSE sensors for end-of-stroke confirmation. Because the 25 mm stroke is very short, side-load stress is minimal, but always guide the load externally on longer strokes.
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 JSID40X25S FAQ
Because the rod passes through both covers, force is equal in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa. The air port size is G1/4.
No, a plain double-rod cylinder drifts without live air, as the adjustable air cushion only decelerates the piston near the stroke end. To maintain a vertical position on air loss, install an external rod lock or a pilot-operated check valve.
