Airtac JSID Double Rod Cylinder JSID100X250S
The AirTAC Airtac JSID Double Rod Cylinder JSID100X250S is a genuine double acting, double rod JIS-standard air cylinder with a Ø100mm bore and 250mm stroke, G1/2 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 JSID100X250S
Delivering 3574 N of equal force in both directions at 0.5 MPa, this 100 mm bore double-rod actuator uses a rod-side pressure area on every stroke. It yields a safe working load of about 2144 N, which translates to lifting roughly 182 kg vertically with a 2:1 safety margin. The twin rods exit both covers to drive opposing tools or carry a sensor cam while preventing rotation under offset loads.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the unit is noticeably shorter than a same-bore ISO 15552 cylinder. It features a G1/2 port, a 32 mm rod, and adjustable 33 mm air cushions at each end. The S suffix denotes a built-in piston magnet for CMSE/DMSE switches that drop directly into the side sensor grooves.

Where the Airtac JSID Double Rod Cylinder JSID100X250S Is Used
Twin-Spindle Machining
Drives two opposing machining heads from a single piston, keeping synchronized cutting forces balanced with equal push and pull thrust.
Symmetric Transfer Gate
Uses the rod extending from the rear cover to actuate a return cam, maintaining a symmetric load path without requiring a second cylinder.
Anti-Rotation Vertical Lift
Lifts roughly 182 kg of guided material using the dual rods to prevent twist and ensure smooth vertical descent without binding.
Is the Airtac JSID Double Rod Cylinder JSID100X250S the Right Cylinder?
At 100 mm this bore sits between the 80 mm option providing 2268 N and the 125 mm providing 5734 N, both rated at 0.5 MPa. Choose a double-rod configuration when your mechanism needs anti-rotation guidance, symmetric load distribution, or twin tooling driven from one piston. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The S suffix magnet enables CMSE/DMSE position sensing. For this 250 mm stroke, ensure external load guides are used to prevent side-load binding.
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 JSID100X250S FAQ
Because the rod passes through both covers, force is equal in both directions: 3574 N at 0.5 MPa, 5003 N at 0.7 MPa, and a theoretical max of 729 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod, and adjustable 33 mm cushions.
No, the air cushions only decelerate the piston near the stroke ends and do not act as a brake. The load will drift if air is lost or the valve is centered; use an external rod lock or pilot-operated check valve for load holding.
