Airtac JSI Series Standard Cylinder JSI100X415S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X415S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 415mm 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 JSI100X415S
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder brings serious power to compact machinery. It is engineered with an extruded hard-anodized aluminum barrel that eliminates external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease for a long, low-friction service life.
Because the SKU includes the -S suffix, a built-in piston magnet enables CMSE or DMSE electronic switches to drop directly into the side grooves for precise end-position detection. Plan for about 2356 N of real work at 0.5 MPa, which means it lifts roughly 200 kg vertically with a 2:1 safety margin. The unit features a G1/2 port, an M26x1.5 rod thread, and 33 mm adjustable air cushions at both ends to smoothly decelerate the 32 mm rod.

Where the Airtac JSI Series Standard Cylinder JSI100X415S Is Used
Injection Mold Clamping
Provides the 3927 N push force required to secure mid-sized injection mold halves over the 415 mm travel distance.
Heavy Pallet Diversion
Shifts loaded pallets across a packaging line, using the built-in magnet to confirm full extension before the belt resumes.
Vertical Material Lift
Raises components weighing up to 200 kg in a 2:1 margin setup, relying on external guides to stabilize the long 415 mm stroke.
Is the Airtac JSI Series Standard Cylinder JSI100X415S the Right Cylinder?
When sizing this 100 mm bore actuator, consider the 80 mm bore (delivering 2513 N push at 0.5 MPa) for lighter duties, or step up to the 125 mm bore (6136 N push at 0.5 MPa) if your load demands more muscle. The integrated -S magnet pairs perfectly with CMSE/DMSE sensors for automated feedback. Remember that a standard pneumatic cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve. Given the 415 mm stroke, support the rod against side loads and bending moments by using external guide rails to prevent premature seal wear.
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 JSI100X415S FAQ
This 100 mm bore cylinder uses a G1/2 air port and an M26x1.5 rod thread. It generates 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.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It uses a hard-anodized aluminum extrusion without external rods, and the -S magnet allows CMSE/DMSE sensors to fit directly into the side grooves.
