About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30
The AirTAC SAIJ32X65-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the retract end position. It provides a usable travel window of 35-65 mm, allowing you to dial back the 65 mm nominal stroke by up to 30 mm without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This model uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. The rear adjuster functions purely as a travel stop to set deceleration, not as a lock, so live air is required to hold a load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30 Is Used
Machine Changeovers
Dial in the exact 35-65 mm retract position during product size changeovers on a packaging line without swapping out the entire cylinder.
End-Stop Calibration
Fine-tune the final end position during machine commissioning to absorb mechanical tolerances and achieve precise part seating.
Variable Retract Stops
Set custom retraction limits for delicate assembly tasks where the full 65 mm stroke would apply excessive travel or pressure.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when an application requires exact end-position tuning during commissioning or frequent product-size changeovers, rather than relying on a fixed-stroke SAI cylinder. If your process needs slightly less force and a smaller footprint, stepping down is an option, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa for heavier payloads.
When matching this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 65 mm stroke, 30 mm adjustment range, PT G1/8 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the adjuster. The 12 mm rod and M10x1.25 thread handle moderate side loads well, though long unsupported strokes still require external guidance.
Quick checklist
- ✓ 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 SAIJ32AX65-30 FAQ
A rear adjusting screw lets you shorten the effective stroke by up to 30 mm, creating a usable travel window of 35-65 mm. This allows you to set the exact retract end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
