Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X275-100S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X275-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 275mm 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 JSIJ32X275-100S
Its extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The integrated -S magnet allows side-groove CMSE/DMSE sensors to track position directly.
The -100 code means an external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 175-275 mm. You fine-tune the end position without changing the cylinder itself, while the retract end stays fixed. This double-acting double-rod unit runs at 30-800 mm/s. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load on air loss, so fit an external rod lock or pilot-operated check valve for vertical holding.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

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 JSIJ32X275-100S Is Used
Stop Position Tuning
Use the 100 mm adjuster window to dial in the exact extend stop on a test rig without machining new spacers or swapping cylinders.
Consolidated Spares
Keep one 275 mm unit in maintenance stock and shorten the extend stroke on-site to cover various shorter sub-200 mm tasks.
Compact Clamping
Clamp small electronic housings in a tight cell where the shorter JIS profile barrel saves valuable machine footprint.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X275-100S the Right Cylinder?
When sizing, the 32 mm bore sits at the low edge of the range. If your task needs more push, the neighbouring 40 mm bore provides 628 N at 0.5 MPa. Conversely, if 402 N is excessive, you would step out of the JIS family. The adjustable stroke is ideal for sharing a single spare across multiple stroke variants or tuning end positions on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S suffix means a magnet is already fitted for CMSE/DMSE switches. Because the 275 mm stroke exceeds 300 mm when extended, ensure adequate side-load guidance to prevent uneven seal 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 JSIJ32X275-100S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. It features a G1/8 port.
The 275 mm nominal stroke is the maximum. The external stop screw lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable extend range of 175-275 mm. The retract end remains fixed.
