About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-50
The AirTAC SAIJ32X750-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, allowing you to fine-tune the travel window from 700 to 750 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance in demanding environments.
The rear stopper screw lets you dial in exact end positions during commissioning without adding external stops. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that this adjuster acts as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-50 Is Used
Machine Changeover
Quickly modify the 700-750 mm end-stop to accommodate different product lengths on a packaging line without swapping the cylinder.
Position Calibration
Fine-tune the retract stroke during initial setup to achieve exact positioning without fabricating custom external spacers.
Material Handling
Adjust the travel distance on the fly to push varying package sizes onto a conveyor while maintaining safe deceleration.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-50 the Right Cylinder?
Choose this 32 mm bore when you need precise 700-750 mm travel adjustments; step down to a 20 mm bore if your force requirements are lower. With a 750 mm stroke, the 12 mm rod requires an external guide to prevent side-load damage. For load-holding without live air, select the SAIL or BSAI series instead.
To match this ISO 15552 cylinder, specify a 32 mm bore, 750 mm stroke, 50 mm adjustment, PT tapered port, and SUS304 (B) rod material. It operates at 30-800 mm/s and uses dual air cushions to decelerate the load.
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 SAIJ32BX750-50 FAQ
A rear stopper screw lets you shorten the effective travel by up to 50 mm, creating a usable 700-750 mm window. It acts as a mechanical stop and does not lock the load without live air.
At 0.5 MPa, this 32 mm bore double-acting 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.
