Airtac JSI Series Standard Cylinder JSI100X55S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X55S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 55mm 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 JSI100X55S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X55S is a double-acting JIS-standard profile cylinder built for heavy machinery. Its extruded hard-anodized aluminum barrel omits external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The bore dictates a G1/2 port and an M26x1.5 rod thread, while a 33 mm adjustable air cushion decelerates the piston at both ends.
A heterogeneous two-way piston seal retains grease for extended, low-friction operation. Plan for roughly 2356 N of real work at 0.5 MPa, which safely lifts about 200 kg vertically with a 2:1 margin. Because this SKU includes the -S magnet, CMSE or DMSE sensors drop directly into the side grooves for position detection.

Where the Airtac JSI Series Standard Cylinder JSI100X55S Is Used
Injection Mold Clamping
Provides the 3927 N push force needed to secure mid-sized injection mold halves during polymer injection cycles.
Pallet Diverting
Actuates heavy-duty diverter arms on packaging lines, moving loaded pallets laterally with reliable 3574 N pull force.
Vertical Lift Gates
Raises and lowers material handling safety gates, safely lifting components up to 200 kg using a 2:1 safety margin.
Is the Airtac JSI Series Standard Cylinder JSI100X55S the Right Cylinder?
When sizing this 100 mm bore, stepping down to the 63 mm JSI yields 1559 N of push at 0.5 MPa, whereas moving up to the 125 mm bore provides 6136 N. The 55 mm stroke keeps the rod compact, but if your application exceeds 300 mm, add an external guide to prevent rod bending under side loads. Remember that the air cushion only decelerates the piston near stroke end; it will not hold a load if air pressure drops. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 JSI100X55S FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull. At 0.7 MPa it delivers 5497 N push and 5003 N pull, with a theoretical maximum of 801 kgf at 1.0 MPa. The air port is G1/2.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The extruded aluminum barrel lacks external rods, and the included -S magnet supports CMSE/DMSE sensors.
