About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-30
The AirTAC SAIJ32X150-30 is a double-acting ISO 15552 profile cylinder with a rear screw stopper that trims the effective stroke by up to 30 mm, creating a 120-150 mm usable travel window. It delivers 402 N of push force at 0.5 MPa and reaches 724 N at 0.9 MPa, matching the standard SAI output class.
This unit features a SUS304 stainless steel piston rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is not magnetized for position sensing.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-30 Is Used
Machine Setup Tuning
Dial in the exact 120-150 mm retract end-position during initial commissioning to perfectly align a pick-and-place head without machining spacers.
Product Changeover
Quickly adjust the stroke stop on a packaging line when switching to a different carton size, saving setup time and avoiding cylinder replacement.
Variable End Stops
Fine-tune the clamping reach on a small fixture where the raw 150 mm stroke would overtravel, using the rear screw to cushion the final position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-30 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning during commissioning without adding external stops or swapping the cylinder. If your application requires less force, stepping down is not an option below 32 mm, but if you need roughly 628 N of push force at 0.5 MPa, move up to the 40 mm bore. The 12 mm rod and M10x1.25 thread handle moderate side loads, but a 150 mm stroke still benefits from an external guide for heavy loads.
This cylinder is dimensionally interchangeable per ISO 15552. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The rear adjuster acts only as a travel stop, not a lock; it cannot hold a load without live air, so consider an external pilot-operated check valve or a SAIL lock cylinder for load-holding.
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 SAIJ32BX150-30 FAQ
The rear adjuster is a mechanical stopper that lets you shorten the nominal 150 mm stroke by up to 30 mm, providing an effective travel range of 120-150 mm. It sets the retract end-position but does not lock the load without continuous air pressure.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
