The AirTAC Airtac JSID Double Rod Cylinder JSID50X900 is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 900mm 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.
Delivering 825 N of thrust in both directions at 0.5 MPa, this 50 mm bore double-rod cylinder brings symmetric power to demanding setups. The twin-rod layout creates an equal push and pull force while preventing piston rotation. It yields a safe working load of roughly 495 N, which is enough to vertically lift about 42 kg with a 2:1 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. Air enters via a G1/4 port, and adjustable cushions decelerate the stroke at each end. Note this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors without switching to the -S variant.

| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 200 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

JSI-family variants: JSI (double acting), JSID (double rod), JSIJ (adjustable stroke). Mounting: LB / FA / FB / CA / CB / CR / TC / TCM1 / TCM2. Thread PT (blank) / G.
Drives two synchronized end-effectors from a single piston, ensuring perfectly matched timing on a 900 mm parts transfer line.
The dual rods prevent twist during long 900 mm extensions, keeping precision clamps perfectly aligned on packaging machinery.
Provides equal force both ways to raise and lower a 42 kg vertical load platform, maintaining a balanced load path without drift.
This 50 mm bore sits between the 32 mm option, offering 345 N each way, and the 63 mm size, providing 1402 N. Choose a double-rod configuration when your application demands anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this model has no -S suffix, it cannot support magnetic sensing. The 900 mm stroke is substantial; always use external guides to prevent rod bending and manage side loads.
Quick checklist
Because the rod exits both ends, force is equal in both directions: 825 N at 0.5 MPa and 1154 N at 0.7 MPa. The theoretical maximum is 168 kgf at 1.0 MPa. It uses a G1/4 port, operates at 30-800 mm/s, and has a 20 mm rod with an M18x1.5 thread.
No, this SKU lacks a magnet and cannot take CMSE or DMSE sensors. Additionally, the adjustable air cushion only decelerates the piston near stroke end; it does not lock. For a suspended load, you must install an external rod lock or a pilot-operated check valve to prevent drifting.
