Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10S 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 JSIJ50X700-10S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS actuator features an external adjuster that fine-tunes the extend stroke by up to 10 mm on site. The nominal 700 mm travel remains the maximum, yielding a usable 690-700 mm window while the retract end stays fixed. You avoid swapping the whole cylinder when a target position shifts slightly. Built with an extruded hard-anodized aluminum profile barrel, the body is shorter and more compact than a same-bore ISO 15552 unit. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves.
This model handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin. Air connections use a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends. Note that the cushion only absorbs end-of-stroke energy; the piston will drift on air loss. For a securely held load, fit an external rod lock or a pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10S Is Used
Transfer Line Positioning
Dial in the exact push-off point of parts on a conveyor using the 10 mm external adjuster, ensuring precise handoff without reprogramming the machine.
Vertical Material Lift
Elevates approximately 50 kg of inventory using the 0.5 MPa push force, with the built-in magnet confirming the full 700 mm upstroke.
Carton Flap Folding
Folds heavy packaging flaps over long distances, using the 20.5 mm adjustable cushions to soften the end impact and prevent crushing the board.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10S the Right Cylinder?
When sizing, step down to a 40 mm bore for lighter duties (528 N pull at 0.5 MPa) or up to a 63 mm bore for heavier loads (1402 N pull at 0.5 MPa). The 10 mm extend adjuster is ideal for sharing a spare across slightly different stroke variants or finalizing end positions on-site without machining. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix ensures you have the magnet for position sensing. Because the 700 mm stroke is long, always support the load with an external guide to prevent rod bending and premature seal wear.
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 JSIJ50X700-10S 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. The air port is G1/4.
The external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 690-700 mm. The nominal 700 mm is the maximum, and the retract end remains fixed.
