Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X1000-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X1000-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 1000mm 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 JSIJ50X1000-40S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features a hard-anodized aluminum barrel that is noticeably shorter than a same-bore ISO 15552 unit. The integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for precise position detection. It connects via a G1/4 port and handles a safe working load of about 589 N, which translates to roughly 50 kg lifted vertically with a 2:1 margin.
The -40 code means an external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 960 to 1000 mm while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder, and the adjustable air cushions absorb 20.5 mm of impact at both ends. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for load holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X1000-40S Is Used
Long-Reach Press Down
Uses the full 1000 mm extend to reach down into a deep fixture, with the 40 mm adjuster fine-tuning the exact pressing depth on-site.
Extended Transfer Push
Pushes parts across a wide conveyor gap, dialing in the 960 to 1000 mm stroke window to hit the exact stop location without changing cylinders.
Vertical Material Lift
Lifts approximately 50 kg of stock vertically using the 2:1 safety margin on the 0.5 MPa push force, relying on the -S magnet for top and bottom confirmation.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X1000-40S the Right Cylinder?
When sizing, the 63 mm bore steps up to 1559 N push at 0.5 MPa, while the 40 mm bore drops to 628 N, so the 50 mm bore sits squarely in the mid-range. The adjustable stroke is ideal for sharing a spare across stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix confirms the magnet is present for sensors. Because the 1000 mm stroke is long, always support the rod against side-loads and use an external guide to prevent 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 JSIJ50X1000-40S 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.
An external stop screw lets you shorten the extend stroke on-site by up to 40 mm. The nominal 1000 mm stroke is the maximum, so the usable extend range is 960 to 1000 mm. The retract end is fixed, and this mechanism sets end position rather than locking the load.
