Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40S 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 JSIJ40X600-40S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder shortens on-site by up to 40 mm so you can fine-tune the extend end position without swapping the unit. The external stop screw yields a usable extend stroke of 560-600 mm while the retract end stays fixed. It handles about 377 N of real work, roughly 32 kg lifted vertically with a 2:1 margin. An extruded hard-anodized aluminium barrel removes external rods, making the body shorter and more compact than an ISO 15552 cylinder of the same bore.
A G1/4 port feeds the double-acting single-rod piston, and the -S suffix means a built-in magnet is present for CMSE/DMSE switches that drop directly into the side grooves. Adjustable air cushions of 20.5 mm at each end absorb kinetic energy near stroke end. The stop screw sets end position only; it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load against air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40S Is Used
Transfer Push-Off Tuning
Trim the 600 mm extend stroke by up to 40 mm on-site to dial in the exact push-off distance for varying box sizes on a conveyor line.
Pallet Stop Adjustment
Set the precise pallet stop position without changing the cylinder, using the external adjuster to compensate for pallet thickness variations.
Vertical Press Positioning
Fine-tune the downward extend end point for light pressing tasks, relying on the 628 N thrust at 0.5 MPa to seat components accurately.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40S the Right Cylinder?
At 0.5 MPa this 40 mm bore gives 628 N push and 528 N pull; step down to a 32 mm bore for 402 N push, or up to a 50 mm bore for 982 N push if you need more thrust. The 40 mm adjustable window is ideal for sharing one spare across several stroke variants and trimming the extend end position on the machine. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1 and TCM2. Because the 600 mm stroke is long, always support the load with an external guide to prevent rod bending and side-load wear. The -S magnet supports CMSE/DMSE sensors.

- ✓ 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 JSIJ40X600-40S FAQ
This 40 mm bore cylinder has a G1/4 port and generates 628 N push / 528 N pull at 0.5 MPa, and 879 N push / 739 N pull at 0.7 MPa. 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 40 mm, giving a usable extend range of 560-600 mm. The retract end is fixed, and the stop sets position only, not load holding.
