Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-20S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 200mm 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 JSIJ32~50 Adjustable Cylinder JSIJ40X200-20S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder uses an external adjuster to shorten the extend stroke on site by up to 20 mm. The nominal 200 mm stroke remains the maximum travel, yielding a usable 180-200 mm extend range while the retract end stays fixed. Because the hard-anodized aluminum extrusion omits external retaining rods, the overall body is noticeably shorter and more compact than a same-bore ISO 15552 unit. The integrated -S piston magnet allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
In practical terms, it handles a safe working load of roughly 377 N, which translates to lifting about 32 kg vertically with a 2:1 safety margin. Air connects via a G1/4 port, driving the 16 mm rod at speeds of 30-800 mm/s. Adjustable 20.5 mm cushions at both ends tame end-of-stroke impact, though the cylinder relies on live air; a separate rod lock or pilot-operated check valve is required if you need to hold a load during a pressure drop.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-20S Is Used
Clamp Position Trimming
Dial in the exact 180-200 mm clamping reach on a machining fixture using the external adjuster, accommodating varying part thicknesses without replacing the cylinder.
Transfer Gate Timing
Fine-tune the extend stop on a sorting diverter to synchronize package routing precisely, relying on the 628 N push force to shift loads reliably.
Vertical Lift Stops
Lift approximately 32 kg of inventory using the integrated magnet for position feedback, adjusting the extend endpoint on-site to match varying shelf heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-20S the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to a 50 mm bore raises it to 982 N. The -20 mm adjustable window is ideal for fine-tuning the extend end position on the machine without physically swapping the cylinder, letting you standardize one spare across slight stroke variants. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The included -S magnet supports CMSE/DMSE switches for end-of-stroke signaling. For this 200 mm stroke, ensure external guide rails are used to absorb any lateral side loads and prevent rod binding.
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 JSIJ40X200-20S FAQ
This 40 mm bore cylinder generates 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 uses a G1/4 air port, a 16 mm rod, and features 20.5 mm adjustable air cushions at both ends.
The -20 indicates a 20 mm external adjustment window that shortens the extend stroke on site. The nominal 200 mm stroke is the maximum travel, and you can reduce the extend end position down to 180 mm without changing the cylinder. The retract end remains fixed, and this stop mechanism decelerates the piston but does not lock or hold the load without live air pressure.
