About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10S
The AirTAC SAIJ160X135-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering substantial thrust for heavy-duty automation. With a 160 mm bore, it generates 14074 N of push force at 0.7 MPa and 9425 N of pull force. The built-in rear stopper allows you to fine-tune the effective travel down from the 135 mm nominal stroke, providing a precise 125-135 mm usable window to dial in end positions without adding external stops.
This adjustable-stroke configuration ships with a standard carbon steel piston rod and a PT tapered port thread. Because it includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors via the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster functions purely as a travel stop and deceleration point, meaning it will not hold a load safely without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10S Is Used
Heavy Press Tuning
Dial in the exact 125-135 mm end-stop during heavy press commissioning to accommodate material thickness variations without remounting the cylinder.
Product Changeover
Quickly adjust the retract distance for different product sizes on a packaging line, using the rear screw to set a new precise end position.
Assembly Station Setup
Fine-tune the stroke end-point on heavy assembly fixtures to ensure consistent seating force, leveraging the 14074 N thrust capacity at 0.7 MPa.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-10S the Right Cylinder?
Choose this 160 mm bore when your application requires more force than a 125 mm cylinder, which provides 8590 N of push force at 0.7 MPa. The adjustable 125-135 mm travel window is ideal for machine setup and product changeover, allowing you to reposition the end-of-stroke point on the fly rather than swapping to a fixed-stroke SAI cylinder. For any load-holding requirements during an air pressure loss, you must integrate an external pilot-operated check valve or select a dedicated locking cylinder like the SAIL or BSAI, as the SAIJ adjuster is strictly a stop. Although 135 mm is a moderate stroke, the 40 mm rod diameter and M36x2 rod thread provide excellent rigidity against side loads, though external guidance is always recommended for optimal bearing life.
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 SAIJ160X135-10S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 135 mm nominal stroke by up to 10 mm. This creates a 125-135 mm usable travel window, allowing precise end-position tuning at commissioning without replacing the cylinder.
