About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-40S
The AirTAC SAIJ160X165-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 125 to 165 mm, allowing you to dial back the nominal 165 mm stroke by up to 40 mm during commissioning. This bore size delivers a robust 10053 N pull force at 0.5 MPa, making it suitable for moving heavy industrial loads.
Unlike a fixed-stroke SAI, this model lets you fine-tune the retract end position without swapping the cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-40S Is Used
Product Changeover
Dial in the exact retract distance within the 125-165 mm window when switching machinery between different product sizes without changing hardware.
Heavy Assembly Press
Leverage the 10053 N pull force at 0.5 MPa to seat large industrial components, using the rear stopper to fine-tune the final pressing position.
End-Stop Calibration
Trim up to 40 mm of travel during machine commissioning to perfect the end-of-stroke deceleration and absorb mechanical tolerances automatically.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X165-40S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial force, offering 10053 N pull at 0.5 MPa, and you need precise retract positioning. If your force requirements are lower, stepping down to a 125 mm bore yields 5734 N of pull force at the same pressure. The PT tapered port is G3/4, and the carbon steel rod with an M36x2 thread provides high structural rigidity, though long unsupported strokes still require an external guide to manage side loading.
Choose the adjustable-stroke SAIJ over a fixed SAI when accommodating product size changeovers on a line. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the rear adjuster and air cushions only decelerate the travel end, this cylinder will not hold a load without live air. For true fail-safe load holding, specify an AirTAC SAIL or BSAI cylinder 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 SAIJ160X165-40S FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force at 0.7 MPa. It operates at speeds of 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke. For this SAIJ160X165-40-S model, you can trim the 165 mm nominal stroke back by up to 40 mm, creating a usable travel window of 125 to 165 mm. It is a travel stop, not a lock, and does not hold the load without live air pressure.
