About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-20
The AirTAC SAIJ160X175-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 155 to 175 mm usable travel window. Delivering a robust 18095 N of push force at 0.9 MPa, it handles heavy loads using a 40 mm carbon steel rod and a PT G3/4 tapered port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This adjustable-stroke model allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It features variable air cushions at both ends and operates at speeds from 30 to 500 mm/s. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-20 Is Used
Heavy Press Tuning
Dial in the 155-175 mm travel window during machine commissioning to set precise pressing depths on heavy assemblies without external stopper blocks.
Product Changeover
Quickly adjust the retract end-position by up to 20 mm to accommodate different product sizes on a single production line.
Assembly Station Setup
Fine-tune the end stop during initial equipment setup to perfect the mating distance of heavy components, leveraging the 18095 N push force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-20 the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust, stepping up from a 125 mm bore that provides 11045 N at 0.9 MPa. An adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, unlike a fixed-stroke SAI cylinder. For load-holding without live air, use an SAIL or BSAI cylinder instead of relying on the rear stopper. To replace an ISO 15552 cylinder, match the 160 mm bore, 175 mm stroke, 20 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts. For this 175 mm stroke, an external guide is recommended to manage side loads.
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 SAIJ160X175-20 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 9425 N of pull force. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 175 mm down to 155 mm, creating a 20 mm adjustable window. This stopper sets the retract end position but does not lock or hold the load without continuous air pressure.
