About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X50-30
The AirTAC SAIJ32X50-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push force at 0.5 MPa and utilizes a G1/8 port. By integrating an external adjusting screw, this 50mm nominal stroke unit provides a usable travel window of 20-50mm, allowing you to dial in the exact retract position without swapping components.
The carbon steel piston rod features an M10x1.25 thread, providing a robust interface for your tooling. Sensor grooves on both sides of the extruded aluminum barrel accept CMSE or DMSE switches if you add a magnet later. The rear stopper acts purely as a travel end deceleration device, not a lock, so live air is required to hold the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X50-30 Is Used
Machine Changeover
Dial in the 20-50mm travel window rapidly when switching between product sizes on a packaging line, avoiding physical cylinder swaps.
End-Stop Tuning
Fine-tune the retract position during initial commissioning using the rear screw, hitting exact mechanical endpoints without adding external shims.
Light Assembly Push
Utilize the 402N push force at 0.5 MPa for light-duty part seating, relying on the 27mm cushion to soften the impact at the end of travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X50-30 the Right Cylinder?
Choose this 32mm bore when you need precise retract end-position tuning during commissioning or product changeover, saving the cost of external stops. If your application requires less force, stepping down is not an option below 32mm in this series, but if you need more clamping power, a 40mm bore provides 628N at 0.5 MPa. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the SAIJ adjuster.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 32mm bore, 50mm stroke, 30mm adjustment range, PT tapered port thread, carbon steel rod, and no magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32X50-30 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 30mm. This creates a usable travel window of 20-50mm, allowing you to set the exact retract end position without changing the cylinder.
At 0.5 MPa, it provides 402N of push force and 345N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 801N.
