Airtac JSID Double Rod Cylinder JSID40X450S
The AirTAC JSID Double Rod Cylinder JSID40X450S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 450mm 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 JSID40X450S
Delivering 528 N of equal force in both directions at 0.5 MPa, this 40 mm bore double-rod actuator uses the pull-side area on every stroke. The G1/4 port feeds a hard-anodized aluminum profile barrel that is noticeably shorter than a same-bore ISO 15552 cylinder.
Because a rod exits both ends on one piston, you get a symmetric load path that resists torsional twist and can drive tooling from the back end simultaneously. This -S variant carries a built-in piston magnet for CMSE/DMSE switches in the side grooves. Note that air cushions only decelerate the load; an external rod lock or pilot-operated check valve is required to hold position on air loss.

Where the Airtac JSID Double Rod Cylinder JSID40X450S Is Used
Symmetric Transfer Pusher
Drives a conveyor diverter with equal push and pull force, using the twin rods to keep the tooling perfectly aligned without rotating under load.
Twin-Tool Machining Station
Operates two opposing machining heads from a single piston, ensuring both ends move simultaneously with identical 528 N force at 0.5 MPa.
Dual-End Sensor Cam Drive
Uses the rear rod extension to trigger external CMSE/DMSE position switches while the front rod performs the primary work stroke.
Is the Airtac JSID Double Rod Cylinder JSID40X450S the Right Cylinder?
Sizing a double-rod unit means looking both ways: the neighboring 32 mm bore yields 345 N each way, while the 50 mm bore provides 825 N. This 40 mm bore sits right in the middle at 528 N. Choose the double-rod layout when you need anti-rotation guidance, twin tooling operation, or a symmetric load path. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix adds the magnet for CMSE/DMSE sensors. With a 450 mm stroke, you must use external guides to prevent rod bending and manage side loads.
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 JSID40X450S FAQ
Force is equal in both directions due to the double-rod design: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a theoretical max of 108 kgf at 1.0 MPa. It operates at speeds from 30 to 800 mm/s. The air port is G1/4.
The rod passing through both covers creates a symmetric load path that prevents piston rotation, making it ideal for guiding heavy tools. It also allows you to mount tooling or sensor cams on the back end. The JIS profile barrel is shorter and more compact than an ISO 15552 cylinder of the same bore.
