About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-75S
The AirTAC SAIJ160X190-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 115-190 mm usable travel window, letting you dial back the 190 mm nominal stroke by up to 75 mm during commissioning. This 160 mm bore generates 14074 N of push force at 0.7 MPa, making it suited for heavy-duty positioning.
Equipped with a carbon steel rod and PT tapered ports, it includes a -S magnet for position sensing with CMSE reed or DMSE solid-state switches. The extruded aluminum barrel offers sensor grooves on both sides. Unlike a fixed-stroke SAI, this adjustable version eliminates the need for external stoppers when tuning end positions.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-75S Is Used
Heavy Machinery Setup
Fine-tune the 115-190 mm travel window during heavy equipment assembly to achieve precise end-position alignment without machining external stoppers.
Product Changeover
Quickly adjust the retract stroke by up to 75 mm on automated lines when switching between product sizes or variants.
Large Assembly Pressing
Leverage the 14074 N push force at 0.7 MPa for pressing heavy components, using the rear screw to set exact compression depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-75S the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust, such as 14074 N push force at 0.7 MPa. If your force requirements are lower, stepping down to the 125 mm bore yields 8590 N at 0.7 MPa. The 75 mm adjustment range is particularly useful for product changeovers, allowing you to fine-tune the end position without swapping the cylinder.
This cylinder uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider the SAIL or BSAI series. Operating speed is 30-500 mm/s.
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 SAIJ160X190-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the 190 mm nominal stroke down to 115 mm. This provides a 115-190 mm usable window for fine-tuning the retract end position at commissioning.
