About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-30
The AirTAC SAIJ32X135-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 105 and 135 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it utilizes a PT G1/8 port and a 12 mm SUS304 stainless steel rod for enhanced corrosion resistance.
The rear adjustment screw acts purely as a mechanical stop to set the retract end-position and cannot hold a load without live air pressure. It shares the standard extruded aluminum barrel with dual sensor grooves, supporting AirTAC CMSE reed and DMSE electronic sensors if a magnet is added later.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-30 Is Used
End-Position Tuning
Dial in the exact retract distance from 105 to 135 mm during machine commissioning to align stops perfectly without machining new brackets.
Product Changeover
Quickly adjust the stroke length on packaging lines when switching between product sizes, using the rear screw to set a new travel limit.
Light Assembly Clamping
Apply up to 345 N of pull force at 0.5 MPa for precise clamping tasks, using the adjustable stop to prevent over-travel on delicate components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-30 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa, or step down if you need less power. An adjustable stroke is ideal for machine changeovers, letting you dial in the exact end-stop without swapping the cylinder or adding external stops. For load-holding without live air, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 135 mm stroke, PT G1/8 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the 12 mm rod and M10x1.25 thread handle moderate side loads, but any stroke over 300 mm requires an external guide.
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 SAIJ32BX135-30 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 105 to 135 mm. It functions as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
At an operating pressure of 0.5 MPa, the SAIJ32X135-30 provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
