Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 350mm 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 JSIJ32~50 Adjustable Cylinder JSIJ32X350-20S
The hard-anodized aluminum extruded barrel contains no tie rods, yielding a clean profile that accepts switches directly in its side grooves. Because the -S suffix denotes a built-in piston magnet, this specific SKU is ready for CMSE or DMSE reed and electronic sensors to track position along its 350 mm stroke.
The -20 code defines a 20 mm external adjuster window that lets you shorten the extend stroke on site, dropping the usable forward travel from the 350 mm maximum down to 330 mm for precise end-position tuning without swapping the cylinder. The retract end remains fixed. It connects via a G1/8 port and features a 12 mm rod with an M10x1.25 thread.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20S Is Used
Adjustable Stop Clamping
Clamps parts in a machining fixture where the exact 350 mm extend point needs 20 mm of on-site adjustment to accommodate different material thicknesses without changing the cylinder.
Transfer Pusher Tuning
Pushes items along a conveyor line, using the external adjuster to dial in the exact 330 to 350 mm stroke length required to align products against a hard stop.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20S the Right Cylinder?
When sizing this 32 mm bore, stepping down is not an option as it is the smallest available JSIJ size, but stepping up to a 40 mm bore raises the 0.5 MPa push force to 628 N if your payload grows. The 20 mm adjustable window is highly useful for sharing a single spare cylinder across multiple stroke variants in a plant, as you can fine-tune the extend endpoint on the floor. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this model features the -S magnet, it supports CMSE and DMSE sensors; a no-S SKU cannot take a sensor. With a 350 mm stroke, you must support the payload with external guides to prevent rod bending and excessive side loading.
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 JSIJ32~50 Adjustable Cylinder JSIJ32X350-20S FAQ
At 0.7 MPa the push is 563 N and the pull is 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The -20 indicates a 20 mm external adjuster window. You can shorten the extend stroke on site from the 350 mm maximum down to 330 mm. The retract end is fixed, and the adjuster only sets the end position; it does not lock the load.
