Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 600mm 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 JSIJ40X600-50S
Generating 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to long-trroke automation. The external stop screw lets you trim the forward stroke by up to 50 mm, giving a usable range of 550 to 600 mm without swapping the actuator. Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 cylinder.
The integrated -S piston magnet supports CMSE/DMSE reed or electronic switches that mount directly into the side grooves. With a practical safe working load around 377 N, it handles roughly 32 kg lifted vertically with a 2:1 safety margin. Pneumatic connections use a G1/4 port, and adjustable air cushions at both ends absorb end-of-stroke impact.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50S Is Used
Long-Reach Transfer
Pushes parts down a 600 mm conveyor lane, using the 50 mm adjuster to dial in the exact hand-off position without reprogramming the machine.
Variable Depth Press
Lowers a lightweight tooling head, trimming the extend stroke on-site to accommodate different material thicknesses while relying on the cushions for smooth stops.
Adjustable Divider Push
Sorts cartons by extending to variable lengths, using the external stop screw to quickly change the push distance for different box sizes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50S the Right Cylinder?
When sizing this actuator, the 40 mm bore sits neatly between the lighter 32 mm option and the heavier 63 mm class. At 0.5 MPa it delivers 628 N push and 528 N pull, stepping up to 879 N push at 0.7 MPa. The 50 mm adjuster window is ideal for fine-tuning the extended end position across multiple stations or keeping a shared spare for machines needing slightly different strokes. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the stroke is 600 mm, always support the load with external guides to prevent rod bending and side-load damage.
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 JSIJ40X600-50S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa.
The nominal 600 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 550 to 600 mm. The retract end remains fixed.
