About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75
The AirTAC SAIJ32X270-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 195 to 270 mm, allowing you to dial back the nominal 270 mm stroke by up to 75 mm during commissioning without adding external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement, though this non-magnet version does not support position sensing. The rear adjuster functions strictly as a travel stop to set end positions and deceleration, meaning it will not hold a load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75 Is Used
Machine Changeovers
Dial in the exact 195-270 mm travel window during product size changeovers without swapping the physical cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-position at commissioning using the rear adjuster screw to perfectly align tooling or fixtures on the line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-75 the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify a 32 mm bore, 270 mm stroke, 75 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. For any stroke of 270 mm or more, ensure you use an external guide to support the load and mitigate side-load stress on the rod.
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 SAIJ32BX270-75 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 270 mm down to a minimum of 195 mm. It sets the end-position and deceleration, but it is not a lock and will not hold the load without continuous air pressure.
