About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-20S
The AirTAC SAIJ160X65-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 45 to 65 mm. Built with a SUS420J2 stainless steel rod (option A) and a position magnet (-S), it operates at speeds between 30 and 500 mm/s. This bore delivers immense thrust, pushing 18095 N at 0.9 MPa, making it ideal for heavy press operations.
The integrated rear stopper screw allows technicians to dial in the exact end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-20S Is Used
Heavy Press Tuning
Fine-tune the 45-65 mm stroke window on heavy pressing tasks to prevent over-travel and adapt to varying material thicknesses during setup.
Machine Changeover
Quickly adjust the retract end-stop during product size changes without swapping out the entire ISO 15552 cylinder or adding external stops.
Robotic End Effectors
Leverage the 18095 N push force and SUS420J2 stainless rod for robust, corrosion-resistant actuation in demanding industrial automation lines.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-20S the Right Cylinder?
Select this 160 mm bore when an application demands high force, generating 14074 N of push at 0.7 MPa, but requires finer end-position tuning than a fixed SAI cylinder offers. If your process needs less than 10000 N of push force at 0.9 MPa, stepping down to the 125 mm bore (11045 N) provides a more compact footprint. The 40 mm rod and M36x2 thread provide excellent resistance to side loads, though any stroke over 300 mm would still require an external guide.
To replace this ISO 15552 cylinder, match the 160 mm bore, 65 mm nominal stroke, 20 mm adjustment range, PT tapered ports, and the -S magnet. Remember that the rear adjuster is strictly a travel stop, not a lock; it cannot hold a load without live air. For true load-holding without pressure, specify an AirTAC SAIL or BSAI model 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 SAIJ160AX65-20S FAQ
At 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. At 0.5 MPa, it provides 10053 N of push force.
The rear adjuster acts as a mechanical stop that allows you to trim the effective travel. For this SAIJ160X65-20-S, the 65 mm nominal stroke can be dialed back by up to 20 mm, creating a 45-65 mm usable travel window for precise end-position tuning.
