About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-100
The AirTAC SAIJ160X180-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 18095N at 0.9 MPa, while its external stopper screw allows you to dial back the 180mm nominal stroke to a usable travel window of 80-180mm. This enables fine end-position tuning at commissioning without swapping the cylinder or bolting on external stops.
Equipped with a 40mm carbon steel rod and M36x2 thread, it handles substantial side loads, though long unsupported strokes still require an external guide. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE solid-state switches, and the mounting set spans Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-100 Is Used
Heavy Press Tuning
Dial in the exact 80-180mm travel window during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Rapidly adjust the retract end-position on a packaging line when switching product sizes, leveraging the 100mm trim range instead of adding external stops.
Large Assembly Setup
Secure heavy components during large-scale assembly operations, relying on the 40mm carbon steel rod to manage significant side loads during positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-100 the Right Cylinder?
Choose this 160mm bore cylinder when an application requires heavy thrust (up to 14074N push at 0.7 MPa) and variable end-stops for product changeovers. If you need less force, stepping down to a 125mm bore yields 8590N at 0.7 MPa. The 100mm adjustment range is ideal for machine setups needing a wide tuning window. Remember, the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-load holding, use an external rod lock, a pilot-operated check valve, or related AirTAC types like SAIL or BSAI. As a dimensionally interchangeable ISO 15552 cylinder, match replacement specs by bore, stroke, 100mm adjustment, PT port, and mounting.
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 SAIJ160X180-100 FAQ
This 160mm bore cylinder generates a push force of 14074N at 0.7 MPa and 18095N at 0.9 MPa. The pull force at 0.7 MPa is 9425N due to the rod area.
The rear adjuster acts as a mechanical stop that trims the effective travel back by up to 100mm, creating a usable stroke window of 80-180mm. It only sets the travel end and does not lock the load without live air pressure.
