About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-50
The AirTAC SAIJ32X900-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 850 to 900 mm, enabling precise end-position tuning without external stops. In the 32 mm bore class, it generates 402 N of push force at 0.5 MPa and reaches speeds of 30-800 mm/s.
This unit includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. Adjustable air cushions at both ends manage deceleration over the long stroke.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-50 Is Used
Machine Setup Calibration
Dial in the exact retract position within the 850-900 mm window during commissioning without swapping hardware.
Product Size Changeover
Quickly adapt the end-stop for different product lengths on a packaging line using the 50 mm adjustment screw.
Variable End-Stop Positioning
Fine-tune the travel end to meet varying process requirements while relying on standard ISO 15552 dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-50 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when you need variable end-stops for machine setup or product changeovers. If your application requires less force, dropping down to a smaller bore is an option, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa for heavier demands. Because the 900 mm stroke is long, an external guide is recommended to manage side loads despite the 12 mm rod diameter. The rear adjuster acts strictly as a travel stop, not a lock; the cylinder will not hold its load without live air pressure. For load-holding without continuous pressure, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32AX900-50 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster allows you to shorten the effective travel from the nominal 900 mm down to 850 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
