Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 900mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100S
The AirTAC SAIJ32X900-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 900 mm nominal stroke that can be dialed back by up to 100 mm, yielding an 800-900 mm usable travel window for precise end-position tuning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. This variant includes a SUS420J2 stainless steel rod and a magnet for position sensing.
Because the adjuster acts purely as a mechanical stop on the retract end, it decelerates the piston alongside the standard variable air cushions but does not hold the load without live air. For load-holding without pneumatic pressure, an external rod lock or a related SAIL pneumatic-lock cylinder is required. The extruded aluminum barrel integrates sensor grooves on both sides, accepting CMSE reed and DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100S Is Used
Long-Stroke Changeover
Dial the retract end-position back by up to 100 mm to accommodate different product lengths on a packaging line without changing out the actuator.
Variable End-Stop Diverter
Fine-tune the 800-900 mm travel window during machine setup to perfectly position a diverting arm on an extended material handling conveyor.
Sensor Calibration Rig
Leverage the CMSE and DMSE sensor compatibility alongside the 100 mm adjustment range to precisely set inspection probe travel limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N push force at 0.5 MPa but needs less travel than a 40 mm bore (which provides 628 N). The 100 mm adjustment range is ideal for product changeovers, allowing you to shift the end-stop from 800 to 900 mm without swapping the cylinder or adding external stops. If you need fixed travel without a rear screw, the standard SAI series is simpler, but this SAIJ model excels at commissioning flexibility.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 900 mm stroke, 100 mm adjustment, PT tapered port threads, and the -S magnet. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. At 900 mm of travel, the 12 mm rod and M10x1.25 rod thread face elevated side-load risks; always use an external guide to support the load and prevent rod binding.
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 SAIJ32AX900-100S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that shortens the 900 mm nominal stroke by up to 100 mm, creating an 800-900 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
