Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X800-75
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic unit brings on-site adaptability to long-stroke tasks. The hard-anodized aluminum profile barrel keeps the body more compact than a same-bore ISO 15552 cylinder, and the G1/4 port matches the standard bore layout.
An external stop screw lets you trim the extend stroke by up to 75 mm, giving a usable range of 725-800 mm without swapping the actuator. In practice it handles about 589 N of real work, roughly 50 kg lifted vertically with a 2:1 margin. Note that this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors, and the retract end remains fixed.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-75 Is Used
Long-Transfer Diverter
Pushes packages across a wide conveyor belt, using the 75 mm adjuster to dial in the exact reach for different box sizes without changing the cylinder.
High-Bay Pusher Arm
Acts as a long-reach arm to eject pallets from a storage lane, trimming the extend stroke on-site to clear racking uprights perfectly.
Material Alignment Gate
Sweeps long workpieces into alignment on a machining line, relying on the adjustable stop to set the final position for various part lengths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-75 the Right Cylinder?
For sizing, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa while the 63 mm bore steps up to 1559 N, letting you tune the force band precisely. The -75 mm adjustable window is ideal for sharing a spare across stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is an 800 mm stroke, always use external guides to prevent rod bending under side loads. Remember this non-magnet SKU cannot support sensors; choose an -S variant for CMSE/DMSE switches.
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 JSIJ50X800-75 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum is 200 kgf at 1.0 MPa, and the air port is G1/4.
The nominal 800 mm extend stroke is the maximum. An external adjuster lets you shorten the extend end by up to 75 mm, yielding a 725-800 mm range, while the retract end stays fixed. This mechanism only sets the end position; it does not lock the load. For load holding on air loss, you need an external rod lock or pilot-operated check valve, as the air cushion only decelerates.
