Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-10 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 JSIJ40X800-10
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings an external adjuster that lets you shorten the extend stroke by up to 10 mm directly on site. The nominal 800 mm stroke remains the maximum travel, while the retract end stays fixed. Its hard-anodized extruded aluminum barrel makes it more compact and shorter than a same-bore ISO 15552 unit. The G1/4 port drives a 30-800 mm/s speed range.
This specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor. For sizing, it handles about 377 N of real work, roughly 32 kg lifted vertically. Remember that the adjustable air cushion only decelerates the piston near the ends; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-10 Is Used
Long-Reach Transfer
Pushes parts along an 800 mm conveyor lane, using the 10 mm adjuster to dial in the exact push-off distance on site.
Storage Lane Sorting
Actuates a diverter arm across a wide packaging track, trimming the extend end position to match varying box sizes.
Vertical Lowering Stop
Lowers a 32 kg fixture and uses the external stop screw to set a precise 790 mm drop, avoiding hard mechanical crashes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-10 the Right Cylinder?
At 0.5 MPa this 40 mm bore yields 628 N push and 528 N pull, sitting neatly between the lighter 32 mm and the stronger 50 mm options. The 10 mm extend-shortening window is ideal for fine-tuning end positions without swapping the cylinder, letting you standardize on one 800 mm body for slightly varied strokes. Mounting choices include FA, LB, TC, TCM1, and TCM2. Because this SKU has no -S suffix, it cannot accept a magnetic switch. As the 800 mm stroke is long, always use 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 JSIJ40X800-10 FAQ
This 40 mm bore cylinder uses a G1/4 port. It delivers 628 N push and 528 N pull at 0.5 MPa, increasing to 879 N push and 739 N pull at 0.7 MPa. The theoretical maximum force is 128 kgf at 1.0 MPa.
The -10 code means an external adjuster lets you shorten the extend stroke by up to 10 mm on site. The usable extend range is 790-800 mm, with 800 mm being the maximum travel. The retract end is fixed, and this stop only sets position; it is not a load lock.
