About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-30S
The AirTAC SAIJ160X140-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 14074N push force at 0.7 MPa, making it suited for heavy-duty positioning tasks. The integrated -S magnet allows seamless operation with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
Equipped with a 30mm adjustment mechanism, this model provides a usable travel window of 110-140mm. This built-in stopper allows precise end-position tuning during commissioning without adding external physical stops. The carbon steel rod and PT tapered port threads are engineered to endure substantial side loads while maintaining a strict 30-500mm/s operating speed range.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-30S Is Used
Heavy Press Fitment
Dial in the exact 110-140mm retraction depth during machine setup to press heavy components accurately without swapping out the entire cylinder body.
Product Changeover
Quickly adjust the end-stop to accommodate varying product sizes on the line, using the 30mm rear screw to fine-tune the travel window on the fly.
Automated Heavy Positioning
Leverage the 14074N push force at 0.7 MPa to move substantial masses, relying on the dual-side sensor grooves for precise end-of-stroke electronic tracking.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-30S the Right Cylinder?
Selecting this 160mm bore provides massive thrust, stepping up from the 100mm bore which yields 5497N at 0.7 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product-size changeovers or fine-tuning the retracted position on the fly. For strokes of 140mm, side-load is manageable, but for any travel over 300mm, an external guide is required.
This SAIJ configuration uses a PT tapered port and a carbon steel rod. It supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts only as a travel stop and deceleration aid, not a lock; for load-holding without live air pressure, specify an SAIL or BSAI cylinder.
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 SAIJ160X140-30S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 13235N of pull force. It can deliver a maximum push force of 18095N at 0.9 MPa.
The rear adjuster acts as an external stopper that lets you mechanically shorten the 140mm nominal stroke down to as little as 110mm. This provides a 110-140mm usable travel window for fine-tuning the end position during commissioning without needing live air to hold the load.
