About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-50
The AirTAC SAIJ160X195-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a substantial 14074N push force at 0.7 MPa, utilizing a 40mm carbon steel piston rod and PT G3/4 porting. By turning the rear stopper screw, you can fine-tune the effective travel window down from the 195mm nominal stroke to anywhere in a 145-195mm range.
This on-the-fly adjustment allows precise end-position calibration during commissioning or product changeover without adding external stops or swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Note that the rear adjuster acts purely as a travel stop for the air cushion and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-50 Is Used
Heavy Press Fit Tuning
Dial in the exact 145-195mm travel window during heavy press assembly to accommodate material thickness variations without re-engineering the machine base.
Product Line Changeover
Quickly adjust the retract end-stop on a 160mm bore cylinder when switching a production line to a new product family, using the 50mm trim range to set new kinematics.
Large Fixture Clamping
Secure large automotive or aerospace fixtures by fine-tuning the clamping end position against the workpiece, leveraging the 10053N pull force at 0.5 MPa.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-50 the Right Cylinder?
Select this 160mm bore when an application requires high thrust—stepping up from a 125mm bore increases your 0.5 MPa push force from 6136N to 10053N. Choose this adjustable-stroke variant over a fixed SAI cylinder when you need a variable end-stop to dial in the exact 145-195mm travel during machine setup. Because the nominal stroke is under 300mm, the 40mm rod handles normal side loads well, though external guidance is still recommended for heavy radial loads. For load-holding without live air, this cylinder is not a lock; you would need to specify a SAIL or BSAI model instead. To match an ISO 15552 replacement, verify the 195mm stroke, 50mm adjustment, PT G3/4 port, and the chosen mounting accessory.

- ✓ 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 SAIJ160X195-50 FAQ
