Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 700mm 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 JSIJ40X700-100S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator features an external adjuster that shortens the extend stroke on-site by up to 100 mm. The nominal 700 mm stroke serves as the maximum, letting you dial the usable extend travel down to 600 mm without swapping the cylinder. Because it is a JIS profile build, the hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 377 N of real work safely, which means roughly 32 kg lifted vertically with a 2:1 margin. The G1/4 air port and built-in magnet round out the hardware.
The -S suffix equips the piston with a magnet for CMSE/DMSE switches that drop directly into the side grooves. Remember that the external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve if you need to hold a suspended load. At a 700 mm stroke, external guides are strongly recommended to prevent rod bending and manage side loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100S Is Used
Conveyor End-Stop Tuning
Dial in the exact 600 to 700 mm push-off distance on a transfer line without machining new hard stops.
Vertical Lift Positioning
Lifts roughly 32 kg vertically with a 2:1 safety margin while allowing 100 mm of on-site extend adjustment.
Shared Spare Inventory
Keep one cylinder as a universal spare for multiple 40 mm machines by adjusting the extend stroke down from 700 mm.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100S the Right Cylinder?
Size this 40 mm bore against its neighbors: the 32 mm bore yields 402 N push at 0.5 MPa for lighter duties, while the 50 mm bore steps up to 982 N for heavier cycles. The 100 mm adjustable window is ideal when you need to fine-tune the extend end position on-site or want a single shared spare across slightly different stroke variants. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The included -S magnet supports CMSE/DMSE sensors. Because the stroke runs 700 mm, always use external guides to absorb side loads and protect the rod from bending.
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 JSIJ40X700-100S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. The air port is G1/4.
The nominal 700 mm stroke is the maximum extend length. An external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 600 to 700 mm. The retract end remains fixed.
