Airtac JSI Series Standard Cylinder JSI100X1050S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1050S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 1050mm 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 JSI100X1050S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X1050S is a double-acting JIS-standard profile cylinder engineered for large-scale automation. Its extruded hard-anodized aluminum barrel omits external rods, making the unit significantly shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The integrated -S piston magnet allows CMSE or DMSE switches to drop directly into the side grooves for precise position detection.
This 1050 mm stroke configuration is a non-standard, made-to-order length that maximizes reach. The two-way NBR piston seal retains grease for low-friction longevity, while the 33 mm adjustable air cushions at both ends decelerate the heavy 32 mm carbon steel rod. Plan for roughly 2356 N of real work at 0.5 MPa, which safely lifts about 200 kg vertically with a 2:1 margin. The G1/2 port ensures high airflow to maintain speed across the long travel distance.

Where the Airtac JSI Series Standard Cylinder JSI100X1050S Is Used
Automotive Body Welding
Indexes heavy welding fixtures along a 1-meter axis, utilizing the 3927 N thrust to shift large steel sub-assemblies between robotic stations.
Pallet Transfer Pusher
Transfers loaded pallets between parallel roller lines, safely moving masses up to 200 kg vertically or horizontally with a 2:1 safety margin.
High-Bay Storage Extraction
Extracts deep-rack totes in automated storage systems where the extended 1050 mm reach is required to clear structural supports.
Is the Airtac JSI Series Standard Cylinder JSI100X1050S the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI80X125S yields 2513 N push at 0.5 MPa, while stepping up to a JSI125X100S provides 6136 N. Because this 1050 mm stroke exceeds the 1500 mm maximum standard range, it requires careful external guiding to prevent rod bending under side loads. A standard cylinder drifts when air is lost or a valve centers; the cushions only slow the piston near the end caps. To hold a suspended load securely, install an external rod lock or a pilot-operated check valve.
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 JSI100X1050S FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull. At 0.7 MPa it provides 5497 N push and 5003 N pull. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
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. It uses a hard-anodized aluminum extrusion without external rods, and the -S magnet enables CMSE/DMSE sensors.
