Airtac JSID Double Rod Cylinder JSID50X100S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X100S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 100mm 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 JSID50X100S
Delivering 825 N of equal force in both directions at 0.5 MPa, this 50 mm bore double-rod actuator uses a symmetric load path to prevent twisting. The twin rods exiting both covers provide anti-rotation guidance while allowing you to drive two tools or mount a rear sensor cam simultaneously. It carries a G1/4 port and adjustable 20.5 mm air cushions at each end.
Built as a JIS-standard profile cylinder, its extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The integrated -S piston magnet works directly with CMSE or DMSE switches in the side grooves. Factoring a 60 percent safety margin, it handles a safe working load of about 495 N, which is roughly 42 kg lifted vertically with a 2:1 ratio.

Where the Airtac JSID Double Rod Cylinder JSID50X100S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 825 N force, keeping cycle times synchronized without adding a second cylinder.
Anti-Rotation Lift Gate
Uses the dual rods to lift and lower a heavy fixture without twisting, maintaining precise vertical alignment under asymmetric loads.
Symmetric Transfer Pusher
Pushes a part down the line while the rear rod simultaneously trips a mechanical valve or sensor cam to confirm the stroke completed.
Is the Airtac JSID Double Rod Cylinder JSID50X100S the Right Cylinder?
Sizing this actuator requires checking both directions: the 50 mm bore yields 825 N each way at 0.5 MPa, sitting neatly between the 40 mm bore at 528 N and the 63 mm bore at 1402 N. Choose the double-rod configuration when your mechanism demands strict anti-rotation, needs twin tooling mounted on opposite ends, or requires a symmetric load path. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S suffix ensures you have the magnet for CMSE/DMSE position sensing. Since the 100 mm stroke is under 300 mm, side-load stress is minimal, but always guide the load externally on longer travels.
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 JSID50X100S FAQ
Because the rod passes through both covers, force is equal in both directions. It provides 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the air port is G1/4.
No, a plain double-rod cylinder drifts without live air, as the adjustable 20.5 mm cushions only decelerate the piston near the end of stroke. To hold a load securely, you must add an external rod lock or a pilot-operated check valve.
