Airtac JSI Series Standard Cylinder JSI50X750STC
The AirTAC Airtac JSI Series Standard Cylinder JSI50X750STC is a genuine double acting JIS-standard air cylinder with a Ø50mm bore and 750mm 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 JSI50X750STC
Generating 982 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an equivalent ISO 15552 unit of the same 50 mm bore. The hard-anodized extruded aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. A built-in piston magnet allows CMSE or DMSE reed and electronic switches to drop directly into the side sensor grooves.
At 0.5 MPa you can plan for roughly 589 N of real work, which translates to lifting about 50 kg vertically with a 2:1 safety margin. The G1/4 air port and M18x1.5 rod thread handle flows for a 30-800 mm/s operating speed. Adjustable 20.5 mm air cushions at both ends decelerate the piston smoothly, though they do not function as a braking lock.

Where the Airtac JSI Series Standard Cylinder JSI50X750STC Is Used
Case Pusher Diverter
Uses the 982 N push rating at 0.5 MPa to deflect heavy cartons across a packaging conveyor over the full 750 mm travel.
Vertical Parts Elevator
Lifts approximately 50 kg of assembled housings between machinery tiers, relying on the TC trunnion to pivot smoothly.
Long-Reach Gate Actuator
Opens and closes sorting chutes on CNC lines, using the built-in magnet and DMSE sensors to confirm end positions.
Is the Airtac JSI Series Standard Cylinder JSI50X750STC the Right Cylinder?
If 982 N of push is excessive for your payload, the smaller JSI40 bore provides 628 N at 0.5 MPa; if you need more power, stepping up to the JSI63 yields 1559 N. This 750 mm stroke variant requires an external guide to prevent rod bending and premature seal wear under side loads. The TC trunnion mount supplied here is ideal for pivoting articulations. Because a standard cylinder drifts when air is lost or a valve is centered, apply an external rod lock or pilot-operated check valve to suspend vertical loads safely.
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 JSI50X750STC FAQ
This 50 mm bore cylinder features a G1/4 port and delivers 982 N push / 825 N pull at 0.5 MPa, 1374 N push / 1154 N pull at 0.7 MPa, with a theoretical maximum of 200 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. It uses an extruded aluminum barrel without external rods and includes a built-in magnet for side-groove sensors.
