Airtac JSID Double Rod Cylinder JSID50X175S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X175S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 175mm 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 JSID50X175S
Delivering 825 N of thrust in both directions at 0.5 MPa, the AirTAC JSID50X175S uses a twin-rod layout to give identical push and pull force. A rod exits each end of the hard-anodized aluminum profile barrel, creating a symmetric load path that resists torsional twist. This JIS build is noticeably shorter than an ISO 15552 cylinder of the same 50 mm bore, and the G1/4 port keeps air delivery compact.
With the -S suffix, this unit carries a piston magnet for CMSE/DMSE switches in the side grooves. The 825 N output translates to a safe working load of about 495 N, or roughly 42 kg lifted vertically with a 2:1 safety factor. The adjustable air cushions decelerate the stroke, but remember a plain cylinder drifts without live air, so fit an external rod lock for held loads.

Theoretical Output Force (Ø50mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |

Where the Airtac JSID Double Rod Cylinder JSID50X175S Is Used
Twin-Tool Transfer
Drives a pusher from the front rod and a return cam from the rear rod simultaneously, keeping cycle times balanced.
Symmetric Lift Station
Uses the equal both-ways force to raise and lower a 42 kg platen with a 2:1 margin without torque twist.
Dual-End Sensing
Pairs the -S magnet with CMSE switches to confirm stroke limits while using the back rod for a secondary stop.
Is the Airtac JSID Double Rod Cylinder JSID50X175S the Right Cylinder?
Sizing the 50 mm bore: the smaller 40 mm bore yields 528 N each way, while the larger 63 mm bore provides 1402 N. This 50 mm option at 825 N is the middle ground. Choose a double-rod configuration when you need anti-rotation guidance, twin tooling driven from both ends, or a sensor cam on the back side. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet enables CMSE/DMSE position sensing. For this 175 mm stroke, ensure external guide rails carry any heavy lateral side-load 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 JSID50X175S FAQ
Force is equal in both directions due to the double rod: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a theoretical max of 168 kgf at 1.0 MPa. The air port is G1/4.
The twin rods create a symmetric load path that prevents rotation, and the rear rod can drive a secondary tool or sensor cam. This JIS profile is also shorter than a same-bore ISO 15552 cylinder.
