Airtac JSI Series Standard Cylinder JSI32X15
The AirTAC Airtac JSI Series Standard Cylinder JSI32X15 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 15mm stroke, G1/8 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 JSI32X15
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built for tight spaces. As a JIS-standard profile unit, it is notably shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine real estate. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for a long, low-friction service life.
Because this is a non-standard 15 mm stroke made-to-order unit, it provides exact short-travel motion. Plan for about 241 N of real work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. It uses a G1/8 port and an M10x1.25 rod thread; since this SKU lacks the -S magnet, it cannot accept CMSE or DMSE position sensors.

Where the Airtac JSI Series Standard Cylinder JSI32X15 Is Used
Micro-Clamp Actuation
Provides precise 15 mm travel for clamping small electronic components on a PCB assembly line without consuming excessive frame space.
Short-Stroke Ejection
Ejects small molded plastic parts from a die, using the 241 N safe working load to push lightweight items clear of the cavity.
Valve Pilot Triggering
Fits into compact pneumatic manifolds to mechanically trigger secondary valves where a full 25 mm standard stroke would cause a collision.
Is the Airtac JSI Series Standard Cylinder JSI32X15 the Right Cylinder?
When sizing this 32 mm bore, stepping up to the 40 mm bore raises the 0.5 MPa push force to 628 N, while 32 mm is the smallest available JSI option. For any vertical load, remember that a plain cylinder drifts when air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near stroke end and never acts as a lock. To hold a load securely, fit an external rod lock or a pilot-operated check valve. To add position sensing, you must switch to the -S magnet variant.
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 JSI32X15 FAQ
The 32 mm bore generates a push of 402 N and pull of 345 N at 0.5 MPa, and a push of 563 N and pull of 483 N at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 port, an M10x1.25 rod thread, and operates at speeds between 30-800 mm/s.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. It features an extruded hard-anodized aluminum barrel with no external rods, making it a space-saving choice for tight machinery.
