About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-50S
The AirTAC SAIJ160X105-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, providing 14074N of push force and 9425N of pull force at 0.7 MPa. Equipped with a magnet for position sensing, this carbon-steel rod unit accepts CMSE reed and DMSE electronic switches along its dual sensor grooves.
With a nominal 105 mm stroke and a 50 mm adjustment range, you can dial the effective travel back to anywhere within a 55-105 mm window. This built-in mechanical stopper allows precise end-position tuning during commissioning without adding external stops. The adjuster and variable air cushions manage deceleration but do not hold the load without live air; for dead-air holding, consider a SAIL or BSAI variant.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-50S Is Used
Heavy Press Tuning
Fine-tune the 55-105 mm end-stop during heavy press commissioning to achieve exact contact depth without machining new spacers.
Product Changeovers
Rapidly adapt clamping positions on a production line by dialing the rear adjuster back up to 50 mm for different material thicknesses.
Variable Assembly Stops
Use the rear mechanical stop to set precise retraction points for large automated assembly fixtures requiring high push forces.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-50S the Right Cylinder?
Choose this 160 mm bore when a 125 mm bore (8590N push at 0.5 MPa) cannot supply enough force, but you want to avoid stepping up to a massive 200 mm unit. The adjustable 55-105 mm travel window is ideal for product changeovers on heavy machinery, letting you set variable end-stops on the fly rather than swapping a fixed-stroke SAI cylinder. To match this ISO 15552 footprint exactly, specify the 160 mm bore, 105 mm stroke, 50 mm adjuster, PT port thread, and the -S magnet option.
Because the 105 mm stroke is relatively short for this large bore, side-load risks are minimal, but always ensure the M36x2 rod thread is properly aligned. Note that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Operating speed is 30-500 mm/s.
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 SAIJ160 Adjustable Cylinder SAIJ160X105-50S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074N of push force and 9425N of pull force. It can deliver a maximum push force of 18095N at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 105 mm nominal stroke by up to 50 mm. This creates a usable travel window of 55-105 mm for fine-tuning end positions without replacing the cylinder.
