AirTAC JSIJ Series Adjustable JIS Cylinders
The AirTAC JSIJ series is an adjustable-stroke JIS profile air cylinder spanning 32-125 mm bores, letting you trim the forward end position on site without external stops.
inventory_22079 models availableSeries Overview
The JSIJ series is the adjustable-stroke version of the AirTAC JSI JIS-standard profile air cylinder. It uses a no-tie-rod extruded-profile body and allows the extend stroke to be shortened on site within a set window by an adjusting screw. The nominal stroke represents the maximum travel.
The range covers seven bores from 32 to 125 mm. Adjust window codes include 10, 20, 30, 40, 50, 75 and 100 mm. As a double-acting cylinder, the push force at 0.5 MPa spans from about 402 N on the 32 mm bore up to about 6136 N on the 125 mm bore. Ports scale with bore size.
Shared design features include standard pneumatic pressure and temperature ranges, along with standard magnetic-switch grooves. The magnet -S option supports switches for position sensing. This is a JIS-standard profile cylinder, not a tie-rod cylinder and not ISO 15552. Use JSIJ to trim the forward end position on site without external stops.

Typical Applications
Conveyor End-Stop Positioning
Trimming the extend stroke on site lets operators fine-tune conveyor stopper arms without external mechanical stops or cylinder swaps.
Packaging Machine Flap Control
The JIS profile body and adjustable forward end position suit packaging lines where carton flap contact points vary by format.
Assembly Press Toning
The 32-125 mm bore range provides 402-6136 N of push force at 0.5 MPa for light pressing and seating tasks on automated assembly lines.
How to Choose the Right Model
Choose the bore based on your load and the 0.5 MPa push force span: 32 mm yields about 402 N, while 125 mm yields about 6136 N. Select the adjust window code (10-100 mm) based on how much you need to trim the extend stroke. Confirm the exact pressure, temperature and cushion specifications from the datasheet.
If you need a fixed stroke, step out to the JSI family. If you need double-rod output, use the JSID. When selecting, confirm these five points: bore size, nominal stroke and adjust window, port and thread size, mounting style, and the magnet -S option for sensor switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and available mounting space
- ✓ Port / thread type (PT / NPT / G)
- ✓ Sensor / magnet option (-S)?
- ✓ Side load — consider a guided model
Frequently Asked Questions
The series spans seven bores from 32 to 125 mm. At 0.5 MPa, the double-acting push force ranges from about 402 N on the 32 mm bore to about 6136 N on the 125 mm bore. Adjust window codes span 10 to 100 mm.
The JSIJ is the adjustable-stroke version of the JSI. It uses an adjusting screw to shorten the extend stroke on site within a set window. The JSI has a fixed stroke, and the JSID features a double-rod design.
No. The JSIJ is a JIS-standard profile cylinder with a no-tie-rod extruded body. It is not a tie-rod cylinder and is not ISO 15552. Confirm mounting interface compatibility from the datasheet before swapping.
No. The JSIJ is a double-acting air cylinder and does not hold position when pressure is lost. If load holding is required, a mechanical lock, rod brake or pilot check valve must be used.
