About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-50
The AirTAC SAIJ32X135-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 85 to 135 mm, allowing you to dial back the nominal stroke by up to 50 mm during commissioning.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Fluid supply connects via a PT tapered G1/8 port.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-50 Is Used
Machine Setup & Changeover
Fine-tune the 85-135 mm travel window during line changeovers to accommodate new product lengths without replacing the cylinder.
Variable End-Stop Positioning
Dial in the exact retract position during initial commissioning, using the 50 mm adjustment screw to perfect the end-stop without adding external shims.
Prototype Testing Rigs
Test different stroke endpoints rapidly on a 32 mm bore actuator, leveraging the 30-800 mm/s speed range to cycle through various travel distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-50 the Right Cylinder?
The 50 mm adjustment range is ideal for prototyping or product changeovers where the exact end position varies, eliminating the need to swap cylinders or bolt on external stops. For fixed travel, use the standard SAI cylinder.
This SAIJ32X135-50 is dimensionally interchangeable per ISO 15552 standards. Configuration details: 32 mm bore, 135 mm stroke, 50 mm adjustment, PT G1/8 port, SUS420J2 rod, no magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster is a mechanical stop, not a lock; it cannot hold a load without live air pressure. For load-holding, consider SAIL or BSAI cylinders.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-50 FAQ
At the maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 135 mm down to 85 mm. This creates a 50 mm adjustable window for fine-tuning the end position without swapping the cylinder.
