About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-10S
The AirTAC SAIJ160X850-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that fine-tunes the retract end-position. It provides a usable travel window of 840 to 850 mm, allowing you to dial in the exact end-stop without adding external mechanical stops. As a large-bore 160 mm actuator operating at 0.9 MPa, it delivers substantial thrust, generating 18095 N of pull force and 14074 N of push force.
This variant integrates a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S model, it contains a magnet ready for AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts strictly as a travel stop to set deceleration, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-10S Is Used
Heavy Press Tolerance Tuning
Dial in the exact 840-850 mm end-stop during machine commissioning to perfectly set the pressing force without physically swapping cylinders.
Product Size Changeover
Quickly accommodate a slightly shorter workpiece on the line by adjusting the rear stopper up to 10 mm, minimizing downtime.
Large Fixture Positioning
Position heavy manufacturing fixtures with high pull force while using the rear adjuster to synchronize multiple actuators.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-10S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy pulling force up to 9425 N at 0.5 MPa, and stepping down to a 125 mm bore would be insufficient for the 5734 N pull requirement. The adjustable stroke is ideal for commissioning fine-tuning or accommodating slight product size changes on a line. If the machine requires the load to be held mechanically without live air, this cylinder is not suitable; consider an AirTAC SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock.
For ISO 15552 replacement, match the 160 mm bore, 850 mm stroke, 10 mm adjustment range, PT G3/4 ports, and SUS420J2 stainless steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 850 mm stroke is long, the heavy piston and 40 mm rod assembly can generate high bending moments; always use an external guide to prevent side-load damage.
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 SAIJ160AX850-10S FAQ
At 0.9 MPa, this 160 mm bore cylinder generates 14074 N of push force and 18095 N of pull force. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as an external stopper that trims the effective stroke. For this SAIJ160X850-10-S model, it creates an adjustable travel window between 840 and 850 mm, allowing precise end-position tuning without replacing the cylinder.
