Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-50S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 75mm stroke, G1/8 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 JSIJ32X75-50S
Its external adjuster lets you shorten the extend stroke by up to 50 mm, giving a usable range of 25 to 75 mm without swapping the cylinder. The retract end stays fixed, while the stop screw sets the exact end position. This JIS profile body is noticeably shorter than a same-bore ISO 15552 unit, and the hard-anodized aluminum barrel keeps weight down.
The integrated -S piston magnet supports CMSE/DMSE switches that mount directly into the side grooves for precise position sensing. Air connections use a G1/8 port, and adjustable air cushions at both ends absorb impact over the 20 mm cushion length. Note that the cushion only decelerates the load; a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve if you need to hold a load vertically.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-50S Is Used
Adjustable Stop Clamping
Dial in the exact 25 to 75 mm extend position on-site to clamp delicate workpieces without reprogramming the machine cycle.
Compact Part Ejection
Fit the short JIS profile body into tight machine cells to push small parts out of a mold, tuning the stroke length to match part variations.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-50S the Right Cylinder?
This 32 mm bore sits at the low edge of the JSIJ range, pushing 402 N at 0.5 MPa; step up to the 40 mm bore for 628 N if your payload grows, or keep the 32 mm for lighter pick-and-place tasks. The -50 mm adjustable window is ideal when you need to fine-tune the extend end position on-site or want a single spare cylinder that covers multiple stroke variants between 25 and 75 mm. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet is already included for CMSE/DMSE sensors. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ32X75-50S FAQ
This 32 mm bore cylinder pushes 402 N and pulls 345 N at 0.5 MPa, pushes 563 N and pulls 483 N at 0.7 MPa, and reaches a theoretical max of 82 kgf at 1.0 MPa. The air port size is G1/8.
The nominal stroke is 75 mm maximum. An external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 25 to 75 mm. The retract end is fixed, and the adjuster sets the end position but does not lock the load.
