About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-50
The AirTAC SAIJ32X100-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 100mm travel back by up to 50mm, creating a precise 50-100mm usable stroke window. This bore size delivers 402N of push force and 345N of pull force at 0.5MPa, operating at speeds between 30-800mm/s.
Instead of swapping components during commissioning, the external stopper screw lets you fine-tune the retract end position on the fly. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting, while the carbon steel rod and M10x1.25 thread provide a robust interface. The adjuster acts strictly as a travel stop and cannot hold loads without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-50 Is Used
Machine Changeover
Dial in the 50-100mm stroke window during product size transitions without physically replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to absorb mechanical tolerances and achieve exact positioning before final lockdown.
Variable Stroke Limiting
Restrict the full 100mm travel dynamically on automated test fixtures where the effective stroke needs to adapt to different part heights.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-50 the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your application requires variable end-stops or frequent product changeovers, as it allows you to dial in the exact position without adding external stops. If your setup needs greater thrust, stepping up to the 40mm bore increases the 0.5MPa push force to 628N. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
This model uses a PT tapered port thread and standard carbon steel rod. For load-holding or safety requirements without live air pressure, consider the SAIL or BSAI series instead, as the SAIJ rear adjuster and air cushions do not function as a lock or brake. For ISO 15552 interchangeability, match the 32mm bore, 100mm stroke, 50mm adjustment, PT port, and standard mounting footprint.
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 SAIJ32X100-50 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 100mm stroke by up to 50mm, giving a usable travel window of 50-100mm. It only sets the end position and does not lock the load without live air.
