Airtac JSI Series Standard Cylinder JSI40X175STC
The AirTAC Airtac JSI Series Standard Cylinder JSI40X175STC is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 175mm 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 JSI Series Standard Cylinder JSI40X175STC
Delivering 628 N of push force at 0.5 MPa, the AirTAC JSI40X175STC is a double-acting JIS-standard profile cylinder built for tight machinery layouts. Its extruded hard-anodized aluminum barrel omits external rods entirely, making the unit significantly shorter and more compact than a same-bore ISO 15552 cylinder without sacrificing structural rigidity.
The bore maps to a G1/4 port and an M14x1.5 rod thread, while a heterogeneous two-way piston seal retains grease for low-friction service life. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing. For real-world sizing, plan for about 377 N of actual work at 0.5 MPa, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin.

Where the Airtac JSI Series Standard Cylinder JSI40X175STC Is Used
Package Diverting Gate
Uses the 628 N push output at 0.5 MPa to snap a routing flap sideways on a 40 mm belt conveyor, diverting cartons into a packing lane.
Small Part Ejection
Kicks molded plastic parts out of an injection mold cavity on a 175 mm stroke, relying on the -S magnet and DMSE switch to confirm the ejection fully cleared.
Clamp Actuation
Extends a secondary hold-down clamp on an aluminum machining fixture, where the compact JIS profile saves valuable Z-axis clearance compared to ISO 15552 units.
Is the Airtac JSI Series Standard Cylinder JSI40X175STC the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm JSI drops the 0.5 MPa push force to 402 N, while moving up to a 50 mm bore increases it to 982 N. This 175 mm stroke falls well within the 1200 mm standard limit, keeping the assembly compact. The factory TC trunnion mount supports pivoting loads, but remember that a standard cylinder drifts if air pressure is lost or the valve is centered; the adjustable air cushion only decelerates the piston near stroke end. For suspended or vertical loads that must hold position safely, add 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 JSI40X175STC FAQ
This 40 mm bore cylinder features a G1/4 air port and an M14x1.5 rod thread. The thrust output is 628 N push and 528 N pull at 0.5 MPa, increasing to 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum of 128 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 machine space. The TC designation means it uses a trunnion mount for pivoting applications, and the included -S magnet allows CMSE or DMSE sensors to track position.
