Airtac JSI Series Standard Cylinder JSI100X155
The AirTAC Airtac JSI Series Standard Cylinder JSI100X155 is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 155mm stroke, G1/2 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 JSI Series Standard Cylinder JSI100X155
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X155 is a double-acting JIS-standard profile cylinder built for heavy machinery. Because it uses an extruded hard-anodized aluminum barrel instead of external rods, the overall envelope is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring long, low-friction life even under demanding cycles.
With a 155 mm stroke, this specific length is a non-standard, made-to-order dimension outside the standard catalog increments. At 0.5 MPa you can plan for about 2356 N of real work, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. It features a G1/2 port, an M26x1.5 rod thread, and adjustable 33 mm air cushions at both ends to decelerate the payload smoothly. Note that this SKU lacks a magnet, so it cannot accept CMSE or DMSE position sensors without upgrading to the -S variant.

Where the Airtac JSI Series Standard Cylinder JSI100X155 Is Used
Injection Mold Clamping
Supplies 3927 N of push at 0.5 MPa to secure mid-sized injection mold halves during material injection.
Pallet Diverting
Drives heavy lane diverters on packaging conveyors, moving loaded pallets with 2356 N of safe working force.
Vertical Lift Gate
Raises and lowers 200 kg mezzanine safety gates using the 155 mm stroke to clear the loading path.
Is the Airtac JSI Series Standard Cylinder JSI100X155 the Right Cylinder?
When sizing this 100 mm bore unit, consider the neighboring JSI bores: the 80 mm offers 2513 N of push at 0.5 MPa if your load is lighter, while the 125 mm provides 6136 N for heavier demands. This 155 mm stroke is a custom length, so confirm delivery times. Since the standard JSI is double-acting, it will drift if air pressure is lost or the valve is centered, as the cushions only decelerate the piston near stroke ends and do not act as a brake; add an external rod lock or pilot-operated check valve for secure load holding. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, or an I/Y/F/U rod knuckle.
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 JSI Series Standard Cylinder JSI100X155 FAQ
This 100 mm bore cylinder delivers 3927 N push and 3574 N pull at 0.5 MPa, 5497 N push and 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. The air port is G1/2, the rod thread is M26x1.5, and it operates at 30-800 mm/s.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, saving valuable machine space. It achieves this via an extruded hard-anodized aluminum barrel with no external rods.
