Airtac JSID Double Rod Cylinder JSID50X25S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X25S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm 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 JSID50X25S
Delivering 825 N of equal force in both directions at 0.5 MPa, this AirTAC double-rod actuator uses a single piston with a rod exiting each end. The symmetric layout creates an anti-twist load path that prevents rotation, making it ideal for driving twin tooling stations or mounting a rear sensor cam. It yields a safe working load of roughly 495 N, which translates to lifting about 42 kg vertically with a 2:1 safety margin.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the unit is noticeably shorter than an ISO 15552 cylinder of the same bore. It features a G1/4 port, M18x1.5 rod threads, and adjustable air cushions at both ends. The built-in magnet (-S) supports CMSE and DMSE switches that drop directly into the side sensor grooves for precise position detection.

Where the Airtac JSID Double Rod Cylinder JSID50X25S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from a single piston, keeping pick-and-place timing perfectly synchronized.
Anti-Rotation Lift
Lifts 42 kg vertical loads without twisting, using the dual rods to maintain strict alignment during elevation.
Dual-Cam Sensing
Uses the rear rod extension to carry a secondary sensor cam, triggering external equipment at the retracted position.
Is the Airtac JSID Double Rod Cylinder JSID50X25S the Right Cylinder?
This 50 mm bore sits between the 40 mm option, which provides 528 N of equal force, and the 63 mm version, which outputs 1402 N. Choose the double-rod configuration when your application demands anti-rotation guidance, symmetric load distribution, or rear-end sensing. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The integrated magnet allows seamless use of CMSE/DMSE switches. Because the stroke is only 25 mm, side-load stress is minimal, but any stroke over 300 mm requires an external guide to prevent 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 JSID50X25S FAQ
Force is equal in both directions because the rod passes through both covers. It outputs 825 N at 0.5 MPa and 1154 N at 0.7 MPa. The theoretical maximum is 168 kgf at 1.0 MPa.
No, a standard cylinder drifts when air is lost or valves are centered. The adjustable air cushion only decelerates the piston near the stroke ends. To hold a load securely, install an external rod lock or a pilot-operated check valve.
