Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-75 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 JSIJ50X700-75
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach actuation. The hard-anodized aluminum barrel omits external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. It handles a safe working load of roughly 589 N, which translates to lifting about 50 kg vertically with a 2:1 margin.
The -75 code defines an external stop screw that shortens the extend stroke on-site by up to 75 mm, giving a usable forward range of 625-700 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. Air connects via a G1/4 port, and adjustable 20.5 mm cushions decelerate the piston at both ends. This non-magnetic SKU cannot take a sensor; add the -S variant for CMSE/DMSE switches.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-75 Is Used
Transfer Push-Off
Pushes parts off a long conveyor belt, using the 75 mm adjuster to dial in the exact drop position without repositioning the cylinder.
Vertical Material Lift
Lifts approximately 50 kg of stock vertically, relying on the 982 N push force at 0.5 MPa with a safe 2:1 working margin.
Long-Reach Clamping
Extends 700 mm to clamp distant workpieces, using the adjustable cushion to soften the stop at the end of the forward stroke.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-75 the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm gives 628 N push at 0.5 MPa, while a 63 mm yields 1559 N. The 75 mm adjuster is ideal for sharing one spare across multiple stroke variants or dialing in a final end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 700 mm stroke, always support the load with an external guide to prevent rod bending and side-load damage. Note that a plain cylinder drifts on air loss—the cushion only decelerates, so fit an external rod lock or pilot-operated check valve if you need to hold a load.
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 JSIJ50X700-75 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum is 200 kgf at 1.0 MPa. It uses a G1/4 port, a 20 mm rod with an M18x1.5 thread, and runs at 30-800 mm/s.
The 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, yielding a usable forward range of 625-700 mm for fine-tuning end positions. The retract end remains fixed, and this stop is not a load lock.
