Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-20
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X600-20
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for tasks that need exact end-position tuning on the floor. The hard-anodized aluminium barrel keeps the overall body more compact than a same-bore ISO 15552 unit. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin.
The external stop screw provides a 20 mm on-site shortening window, meaning your usable extend stroke ranges from 580 mm up to the 600 mm maximum while the retract end stays fixed. Air connects via a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends. Note this SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-20 Is Used
Transfer Push-Off
Pushes parts off a belt at 600 mm, with the 20 mm window trimming the final position to match varying pallet widths.
Vertical Material Lift
Raises a 50 kg load platform using the 0.5 MPa thrust, relying on the adjustable cushion to soften the top stop.
Clamp Stroke Tuning
Extends to clamp parts where raw 600 mm travel is too long, dialing back the extend 20 mm to prevent crushing.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-20 the Right Cylinder?
When sizing, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa, while the 63 mm bore steps up to 1559 N, so this 50 mm model sits right in the middle for medium-force jobs. The 20 mm adjuster is ideal for sharing a spare across stroke variants or fine-tuning a tooling position without swapping the cylinder. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 600 mm stroke is long, always use an external guide to prevent rod bending and side loads. You cannot fit a magnetic switch here; specify the -S variant if you need CMSE or DMSE 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 JSIJ50X600-20 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke on site by up to 20 mm, giving a usable range of 580 to 600 mm. The nominal 600 mm is the maximum, and the retract end remains fixed. This stop only sets the end position; it is not a load lock.
