About the Airtac SAIJ50 Adjustable Cylinder SAIJ50X150-10S
The AirTAC SAIJ50X150-10-S is a double-acting ISO 15552 profile cylinder with a 50mm bore and a 150mm nominal stroke. A rear adjusting screw lets you trim the retract end-position by up to 10mm, creating a 140-150mm usable travel window for exact positioning during commissioning. It delivers 982N of push force at 0.5MPa and uses a standard carbon steel piston rod with PT tapered port threads.
This unit includes a magnet (-S) for position sensing, directly compatible with AirTAC CMSE reed and DMSE solid-state switches mounted in the dual-side sensor grooves. The rear stopper functions purely as a travel end-stop and does not lock the load without live air pressure. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50X150-10S Is Used
End-Stop Calibration
Dial in the exact 140-150mm travel window during machine commissioning to perfect part ejection distances.
Product Changeover
Quickly adjust the retract position by up to 10mm on the line when switching between slightly different product sizes.
Automated Clamping
Provides 982N of clamping force at 0.5MPa while allowing micro-adjustments to the clamping depth without external spacers.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50X150-10S the Right Cylinder?
Choose this 50mm bore when you need 982N push force (825N pull) at 0.5MPa, stepping up from a 40mm bore that yields 628N. The 10mm adjustment window is ideal for fine-tuning end stops during machine setup or product changeover without swapping cylinders or adding external stops. For strokes of 150mm, the 20mm rod and M16x1.5 thread handle moderate side loads, though an external guide is recommended for heavy lateral forces.
To match this ISO 15552 replacement, verify the 50mm bore, 150mm stroke, 10mm adjustment range, PT port threads, and the -S magnet requirement. If your application requires the load to be held mechanically without live air, this cylinder is not a lock; consider the AirTAC SAIL or BSAI series instead.
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 SAIJ50 Adjustable Cylinder SAIJ50X150-10S FAQ
At a standard 0.5MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. It can reach up to 1767N push force at 0.7MPa.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the 150mm nominal stroke by up to 10mm. This creates a 140-150mm travel window for fine-tuning the end position without replacing the cylinder.
