Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75S 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 JSIJ50X600-75S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features an external adjuster that lets you shorten the extend stroke on-site by up to 75 mm. The nominal 600 mm stroke remains the maximum travel, giving a usable extend range of 525 to 600 mm while the retract end stays fixed. This on-site tuning is ideal for matching end positions without swapping the whole actuator. The hard-anodized aluminum extruded barrel omits external rods, making the body noticeably shorter and more compact than a same-bore ISO 15552 cylinder.
Equipped with a G1/4 port and an M18x1.5 rod thread, the unit handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. Because this is a -S SKU, it includes a built-in piston magnet for CMSE or DMSE sensors that mount directly into the side grooves. Remember that a standard cylinder does not hold load on air loss; the 20.5 mm adjustable air cushions only decelerate the piston near the ends, so fit an external rod lock or pilot-operated check valve if you need strict load holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75S Is Used
Sorter Stroke Tuning
Dial in the exact pusher distance on a package diverter by shortening the 600 mm extend stroke up to 75 mm on-site without changing the cylinder mount.
Adjustable Lift Stop
Lift a 50 kg tote vertically using the 982 N push force, tweaking the upper end position with the external adjuster to match varying shelf heights.
Long-Reach Clamping
Extend across a wide machine bed to clamp parts, using the 600 mm travel and fine-tuning the final clamp position via the 75 mm window.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75S the Right Cylinder?
When sizing this actuator, the 50 mm bore provides 982 N push at 0.5 MPa, sitting neatly between the lighter 40 mm option at 628 N and the heavier 63 mm version at 1559 N. The 75 mm adjustable window is a major advantage for maintenance teams, allowing one spare to cover several stroke length variants by simply turning the external stop screw. You can mount it using basic, FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE and DMSE switches for position feedback. Because the 600 mm stroke is quite long, always support the rod against side-load bending and use external guides to prevent premature wear.
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 JSIJ50X600-75S FAQ
This 50 mm bore cylinder pushes with 982 N and pulls with 825 N at 0.5 MPa. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 air port and features a 20.5 mm adjustable air cushion at each end.
An external stop screw lets you shorten the extend stroke on-site by up to 75 mm. The nominal 600 mm stroke is the maximum travel, so the usable extend range is 525 to 600 mm. The retract end is fixed, and this mechanism sets the end position rather than acting as a load lock.
