About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-75
The AirTAC SAIJ160X550-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 550 mm travel back by up to 75 mm, creating a precise 475-550 mm usable window. Built with an extruded aluminum barrel, it delivers massive thrust up to 18095 N at 0.9 MPa, making it ideal for heavy-duty positioning tasks.
This model features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The rear adjustment mechanism acts purely as a mechanical stop to dial in the end position during commissioning; it is not a locking device, so live air pressure is required to hold the load. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-75 Is Used
Heavy Press Tonnage
Provides up to 18095 N of thrust at 0.9 MPa for robust pressing and forming operations.
Product Changeover
Dial the stroke back by up to 75 mm to accommodate different material thicknesses without changing hardware.
Automated Assembly
Handles large payload positioning on ISO 15552 mounting interfaces at operating speeds up to 500 mm/s.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-75 the Right Cylinder?
Choose this 160 mm bore when you need significantly more force than the 100 mm bore provides (7068 N push at 0.9 MPa), but less than the massive 200 mm class (28274 N). The adjustable stroke is perfect for machine setups requiring variable end-stops or product-size changeovers, saving you from swapping out a fixed-stroke SAI cylinder. Because the total stroke is 550 mm, an external guide is recommended to prevent excessive side-loading on the 40 mm rod. If position holding without live air pressure is required, select the 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 SAIJ160 Adjustable Cylinder SAIJ160AX550-75 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. The maximum theoretical force at 1.0 MPa is 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 550 mm down to 475 mm. This enables fine-tuning of the end position during commissioning without adding external stops.
