About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-50
The AirTAC SAIJ32X350-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 300-350mm usable travel window. Delivering 402N of push force at 0.5 MPa, it uses a PT G1/8 port and an M10x1.25 rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This variant uses a SUS304 stainless steel rod (code B) for superior corrosion resistance. The rear adjuster acts as a mechanical stop to fine-tune the retract position without adding external stops. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-50 Is Used
Product Changeovers
Quickly adjust the 300-350mm travel window during line changeovers to accommodate varying package sizes without replacing hardware.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to dial in exact positioning tolerances without external spacers.
Sorting Diverters
Actuate sorting arms on a conveyor line where the rear mechanical stop provides repeatable end-of-travel control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-50 the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa, stepping down from a 40mm bore that provides 628N. The 50mm adjustment window is ideal for product changeovers, allowing you to dial in the exact end-position without swapping cylinders. For operations needing fixed travel, the standard SAI cylinder is a simpler alternative.
Because the 350mm stroke is relatively long for a 12mm rod, an external guide is recommended to prevent excessive side-loading. Note that the rear adjuster and air cushions only decelerate the load; they do not hold position without live air. For fail-safe load holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ32BX350-50 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 50mm. This provides a usable travel window of 300-350mm, enabling fine-tuning of the end position at commissioning without swapping the cylinder.
At an operating pressure of 0.5 MPa, the 32mm bore generates 402N of push force and 345N of pull force. At 0.9 MPa, the push force increases to 724N.
