Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 800mm 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 JSIJ40X800-30
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder integrates an external adjuster that lets you shorten the extend stroke on-site by up to 30 mm. The 800 mm nominal stroke remains the maximum travel, yielding a usable extend range of 770 to 800 mm, while the retract end stays fixed. Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 unit. It handles about 377 N of real work safely, which is roughly 32 kg lifted vertically with a 2:1 margin.
Air connects via a G1/4 port, driving a 16 mm rod with an M14x1.5 thread at speeds of 30-800 mm/s. Adjustable air cushions of 20.5 mm at each end absorb impact energy. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor. Note that the cushion only decelerates the piston; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-30 Is Used
Conveyor Diverter Tuning
Fine-tune the 770 to 800 mm extend reach on-site to match varying package widths without swapping the cylinder.
Long-Reach Pusher
Pushes cartons along a sorting line with 628 N at 0.5 MPa, using the external guide to handle the 800 mm travel.
Elevating Platform Stop
Sets a precise upper extend limit for a lift fixture, relying on a pilot-operated check valve to hold the load safely.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-30 the Right Cylinder?
When sizing, the neighbouring 32 mm bore offers 402 N push at 0.5 MPa, while the 50 mm bore steps up to 982 N if you need more authority. This 40 mm model provides 628 N push and 528 N pull at 0.5 MPa, striking a balance for medium-duty cycles. The -30 mm adjustable window is ideal for fine-tuning the extend end position on-site without changing the cylinder, or for keeping one shared spare across slightly different stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 800 mm stroke is long, always support the load with an external guide to prevent rod bending and side-load damage. As a no-magnet SKU, it cannot accept position sensors.
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 JSIJ40X800-30 FAQ
At 0.5 MPa it delivers 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 model uses a G1/4 air port.
An external stop screw lets you shorten the extend stroke on-site by up to 30 mm. The 800 mm nominal stroke is the maximum travel, so the usable extend range is 770 to 800 mm. The retract end remains fixed, and this stop only sets the end position rather than locking the load.
