Airtac JSID Double Rod Cylinder JSID40X900
The AirTAC JSID Double Rod Cylinder JSID40X900 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm 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.

About the Airtac JSID Double Rod Cylinder JSID40X900
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm bore double-rod actuator uses a single piston with a rod exiting each cover. The G1/4 port feeds the chamber efficiently, while the hard-anodized aluminum profile barrel keeps the total envelope more compact than a same-bore ISO 15552 unit.
Because the rod passes through both ends, you can mount tooling or a sensor cam on the back side simultaneously. This 900 mm stroke SKU lacks a magnet, so it cannot accept CMSE or DMSE switches without upgrading to the -S version. Note that the adjustable air cushions only decelerate the piston near the end caps; they do not hold the load if air pressure drops, which requires an external rod lock or pilot-operated check valve.

Where the Airtac JSID Double Rod Cylinder JSID40X900 Is Used
Dual-End Transfer Pusher
Drives a transfer carriage from one end while the opposite rod carries a fixed cam for mechanical signaling along a packaging line.
Anti-Rotation Lift Station
Uses the twin-rod symmetry to lift and lower a 27 kg vertical load without twisting, ensuring smooth guided elevation over 900 mm.
Symmetric Clamp Assembly
Applies 528 N of clamping force equally on both strokes to hold a workpiece centered between two opposing tool heads.
Is the Airtac JSID Double Rod Cylinder JSID40X900 the Right Cylinder?
When sizing this double-rod unit, the equal-both-ways force is 528 N at 0.5 MPa. Stepping down to the 32 mm bore yields 345 N each way, while stepping up to the 50 mm bore provides 825 N. Choose this symmetric layout when your application demands anti-rotation guidance, twin tooling driven from both ends, or a rear-mounted sensor cam. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Since this specific model has a 900 mm stroke, you must use external guides to prevent rod bending and manage side loads over that extended length. Also, because it lacks the -S magnet, position sensing is not possible on this SKU.
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 JSID40X900 FAQ
This 40 mm bore double-rod cylinder outputs 528 N at 0.5 MPa and 739 N at 0.7 MPa. Because the rod exits both ends, this force is identical in both directions. The theoretical maximum is 108 kgf at 1.0 MPa. It features a G1/4 port, a 16 mm rod, M14x1.5 rod thread, and 20.5 mm adjustable cushions at each end.
No, the air cushions only decelerate motion near the end caps; they do not lock the piston. To hold a vertical load securely, you need an external rod lock or pilot-operated check valve. Additionally, this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors unless you switch to the -S variant.
