Airtac JSI Series Standard Cylinder JSI50X750TC
The AirTAC Airtac JSI Series Standard Cylinder JSI50X750TC 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 JSI50X750TC
Delivering 982 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore. The extruded hard-anodized aluminum barrel sheds external rods for a cleaner, wear-resistant profile, while the heterogeneous two-way piston seal retains grease for long, low-friction life. With a 750 mm stroke and G1/4 ports, it moves at 30-800 mm/s.
Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches without changing to a magnetized variant. For real-world sizing, plan for about 589 N of actual work at 0.5 MPa, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. The adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock the rod.

Where the Airtac JSI Series Standard Cylinder JSI50X750TC Is Used
Packaging Line Diverter
Pushes heavy cardboard cartons at 982 N across a 750 mm gap, using the TC trunnion to pivot smoothly during the transfer stroke.
Palletising Push-Off
Sweeps layered product onto a waiting pallet, where the 50 kg vertical lift equivalent provides ample margin for shifting boxed goods.
Textile Web Guiding
Extends 750 mm to tension and align wide fabric rolls, relying on external guides to prevent rod bending over the long stroke.
Is the Airtac JSI Series Standard Cylinder JSI50X750TC the Right Cylinder?
When sizing this 50 mm bore against its neighbors, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. The integrated TC trunnion mount handles pivoting loads, but at 750 mm of travel you must support the rod against side-load and bending forces with an external guide to prevent premature seal wear.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered. If your application requires the load to be held statically, install an external rod lock or a pilot-operated check valve. Additionally, since this SKU has no -S suffix, it cannot host magnetic sensors; choose the -S version if you need drop-in CMSE or DMSE switches.
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 JSI50X750TC FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum is 200 kgf at 1.0 MPa, and the air port size is G1/4.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore. The adjustable cushions only decelerate the piston near stroke end and do not act as a brake, so you need an external rod lock or pilot-operated check valve to hold a load.
