Airtac JSID Double Rod Cylinder JSID40X75S
The AirTAC JSID Double Rod Cylinder JSID40X75S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 75mm 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 JSID40X75S
Delivering 528 N of thrust in both directions at 0.5 MPa, the AirTAC JSID40X75S uses a twin-rod layout to balance the load path and resist rotation. Because the piston rod passes through both covers, the effective area is identical on the advance and retract strokes, giving you perfectly symmetrical push and pull forces. This JIS-standard profile body is significantly shorter than a same-bore ISO 15552 unit, and its hard-anodized aluminium extrusion omits tie rods for a clean exterior.
The built-in -S magnet allows CMSE or DMSE switches to drop directly into the barrel grooves for end-of-stroke signalling. Adjustable 20.5 mm air cushions at both ends tame the kinetic energy at stroke completion.

Where the Airtac JSID Double Rod Cylinder JSID40X75S Is Used
Dual-End Tooling Shuttle
Drives two opposing pickers at once, using the equal both-ways 528 N force to push and pull parts symmetrically without twisting.
Cam-Triggered Sorting Gate
Uses the extending back rod as a sensor cam for DMSE switches while the front rod actuates the divert gate, saving space on the main actuation face.
Is the Airtac JSID Double Rod Cylinder JSID40X75S the Right Cylinder?
If you need less force, the 32 mm bore offers 345 N both ways, while stepping up to the 50 mm bore yields 825 N. Choose this double-rod configuration when your mechanism requires anti-rotation stability, needs to drive two tools simultaneously from one cylinder, or requires a cam for back-end sensing. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means a piston magnet is already fitted for CMSE/DMSE sensors. At a 75 mm stroke side loads are minimal, but for any stroke over 300 mm you should guide the load externally to prevent rod 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 JSID40X75S FAQ
Because it is a double-rod cylinder, force is equal in both directions using the pull-side area. It provides 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical max of 108 kgf at 1.0 MPa. The air port size is G1/4.
No, a plain double-rod cylinder will drift if air is lost or the valve is centered. The adjustable 20.5 mm cushions only decelerate the piston near the end of stroke and do not act as a brake. For suspended loads you must add an external rod lock or a pilot-operated check valve.
