Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 500mm 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 JSIJ40X500-30
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator features an external adjuster that shortens the extend stroke on-site by up to 30 mm. The nominal 500 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the cylinder. Its extruded hard-anodized aluminum profile barrel omits tie rods entirely, making the body shorter and more compact than an ISO 15552 cylinder of the same bore.
This double-acting single-rod unit handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 margin. It uses a G1/4 port and adjustable air cushions at both ends to decelerate the piston. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; adding the -S variant enables position sensing. Furthermore, the cushion only slows the piston near stroke end and does not hold the load on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-30 Is Used
Conveyor Diverter Tuning
Dial in the exact 470 to 500 mm extend reach to deflect packages of varying widths without re-mounting the actuator.
Pallet Stop Adjustment
Fine-tune the stopping position on-site by up to 30 mm to accommodate different pallet depths while maintaining a fixed retract.
Carton Flap Folding
Adjust the extend endpoint externally to fold different carton heights precisely, avoiding the need for multiple cylinder sizes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-30 the Right Cylinder?
When sizing this model, the 32 mm bore offers a lighter 402 N push at 0.5 MPa, while the 50 mm bore steps up to 982 N if your application needs more authority. The 30 mm adjustable window is ideal for sharing a spare across stroke variants or dialing in exact end positions on-site. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is relatively long, always support the load with an external guide to prevent rod bending and side-load damage. Choose the -S version if you require magnetic position sensing.
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 JSIJ40X500-30 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. This 40 mm bore unit uses a G1/4 air port and features a 16 mm piston rod with an M14x1.5 thread.
An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 470 to 500 mm. The nominal 500 mm stroke is the maximum travel, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
