Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X700-30S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic unit handles about 589 N of real work, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. The G1/4 port feeds a hard-anodized aluminum profile barrel that is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 670-700 mm without swapping the actuator.
The -S suffix equips the piston with a built-in magnet for CMSE/DMSE sensors that mount directly into the side grooves. Because the 700 mm stroke is quite long, external guides are recommended to prevent rod bending under side loads. Note that a plain cylinder does not hold load on air loss—the adjustable cushion only decelerates near the end of travel, so add an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30S Is Used
Transfer Line Divert
Fine-tunes the 700 mm extend position by up to 30 mm on-site to match varying product widths without replacing the cylinder.
Vertical Lift Gate
Lifts roughly 50 kg vertically using the 50 mm bore, relying on the compact JIS profile to save vertical mounting space.
Long-Reach Clamping
Extends across a wide machine bed; the external stop screw allows precise clamping depth adjustment between 670 and 700 mm.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30S the Right Cylinder?
When sizing this 50 mm bore, compare it against the neighbouring 40 mm class (628 N push at 0.5 MPa) and the larger 63 mm class (1559 N push). The on-site 30 mm extend adjuster is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning the end position after a mechanical change. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The integrated magnet supports CMSE/DMSE switches for position feedback. For the 700 mm stroke, always support the load with external guides to avoid rod-bending side loads.
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 JSIJ50X700-30S FAQ
This 50 mm bore cylinder uses a G1/4 port. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push and 1154 N pull at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa.
The nominal 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 670-700 mm. The retract end remains fixed, and this stop is for positioning only, not for holding a load.
