About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-100
The AirTAC SAIJ32X800-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 700-800 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model uses a PT tapered port thread and relies on its external stopper screw to fine-tune the retract end position during commissioning. The adjuster acts purely as a travel stop and does not lock the load without live air pressure. For load-holding requirements, an external pilot-operated check valve or a SAIL locking cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-100 Is Used
Variable Length Stops
Ideal for pushing parts varying in size, using the 100 mm adjustment window to dial in the exact 700-800 mm reach without adding mechanical spacers.
Commissioning Fine-Tuning
Perfect for machine setup where the final retract position needs micro-adjustments at the rear stopper screw rather than re-mounting the entire actuator.
Product Changeover
Enables rapid line changeovers for different product lengths by simply turning the rear adjuster to shift the end-of-stroke position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-100 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning over a long 800 mm travel, avoiding the need to swap cylinders during product changeovers. If the 402 N thrust at 0.5 MPa is insufficient, stepping up to the 40 mm bore yields 628 N of push force. Conversely, if you need to hold a load statically without continuous air, consider the BSAI clamp-lock or SAIL series instead of relying on the SAIJ adjuster.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 800 mm stroke, 100 mm adjustment range, PT G1/8 port, and mounting style. The SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Because the stroke is 800 mm, the 12 mm rod is highly susceptible to side-loading; always use an external guide rail to prevent binding and premature seal wear.
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 SAIJ32AX800-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At a maximum 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating a 700-800 mm travel window. It acts as a mechanical stop to fine-tune the end position and does not function as a lock.
