About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-20
The AirTAC SAIJ160X180-20 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that trims the effective stroke by up to 20 mm. This yields a usable travel window of 160 to 180 mm, allowing you to dial in the exact retract end-position during commissioning without adding external stops. Built with an extruded aluminum barrel, it delivers heavy thrust up to 18095 N at 0.9 MPa.
Equipped with a 40 mm carbon steel rod and a PT G3/4 port, this 160 mm bore unit handles demanding dynamics. It includes adjustable air cushions at both ends to absorb kinetic energy, and its mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-20 Is Used
Heavy Pressing
Fine-tune the 160-180 mm stroke window for heavy pressing or forming tasks that require precise end-position calibration during setup.
Product Changeover
Quickly adapt the retract stop for different product sizes on a high-thrust conveyor line without physically replacing the cylinder.
Machine Setup
Use the rear adjuster to dial in the exact end-of-stroke position during machine commissioning, saving time over fixed-stroke alternatives.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-20 the Right Cylinder?
Choose this 160 mm bore when your application requires substantial force—stepping down to a 125 mm bore yields 11045 N at 0.9 MPa, whereas this size provides 18095 N. The 20 mm adjustable window is ideal for product changeovers where the retract position needs slight shifting, avoiding the need to physically swap a fixed-stroke SAI cylinder. Because the nominal stroke is 180 mm, side-loading is less severe, but always guide heavy loads externally rather than relying on the rod thread. If you need true load-holding without continuous air, consider the SAIL or BSAI variants instead of relying on the rear stopper. This model is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ160X180-20 FAQ
At 0.9 MPa operating pressure, the 160 mm bore provides a push force of 18095 N and a pull force of 9425 N. It can deliver a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster allows you to shorten the nominal 180 mm stroke by up to 20 mm, creating a usable travel window between 160 and 180 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
