About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-40S
The AirTAC SAIJ160X800-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, enabling you to dial back the effective stroke by up to 40 mm. This creates a precise 760-800 mm usable travel window, ideal for fine-tuning end positions during commissioning without swapping hardware. It delivers substantial thrust, offering 10053 N pull force at 0.5 MPa and up to 18095 N push at 0.9 MPa.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and carries the -S magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. With PT tapered G3/4 ports and a 30-500 mm/s speed range, it integrates seamlessly into heavy-duty setups.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-40S Is Used
Heavy Press Tuning
Dial in the exact 760-800 mm end-stop during machine commissioning to accommodate material thickness variations without machining new spacers.
Product Changeover
Quickly adjust the rear stopper by up to 40 mm on a packaging line to handle different large-format carton sizes on the fly.
Variable End Positioning
Use the adjustable travel window to fine-tune the retraction point of heavy 160 mm bore actuators in automated assembly fixtures.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-40S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore lacks sufficient power, as stepping up from 80 mm increases push force at 0.5 MPa from 2513 N to 10053 N. The adjustable stroke is selected over a fixed SAI cylinder when applications require variable end-stops or frequent product changeovers. For any stroke of 800 mm, the long unsupported travel demands an external guide to prevent excessive side-loading on the rod.
Remember that the rear adjuster acts strictly as a travel stop, not a locking device; it cannot hold a load without live air pressure. For load-holding requirements without continuous air, consider an external rod lock or the AirTAC SAIL locking cylinder. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets, and is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160AX800-40S FAQ
The rear adjuster screw lets you shorten the nominal 800 mm stroke by up to 40 mm, providing a usable travel window of 760-800 mm. It acts as a mechanical stop to fine-tune the end position and relies on the standard air cushion for deceleration.
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N, making it suitable for heavy-duty pressing and clamping tasks.
