About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-50S
The AirTAC SAIJ160X750-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, enabling a usable travel window of 700 to 750 mm. Delivering 18095 N of push force at 0.9 MPa, it is built for heavy-duty positioning. This unit includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a high-integrity pneumatic seal.
Equipped with a magnet (-S) for position sensing, it works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-sided sensor grooves. The rear stopper allows fine end-position tuning at commissioning without external stops, though it acts only as a travel limiter and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-50S Is Used
Heavy Press Tuning
Dial in the exact 700-750 mm end position during heavy press commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Adjust the retract stopper on the fly to accommodate different package sizes on a packaging line, saving retooling time.
Large Assembly Jigs
Leverage the 18095 N push force and SUS304 rod for robust, corrosion-resistant actuation in large-scale industrial assembly jigs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-50S the Right Cylinder?
Choose this 160 mm bore when the 100 mm class (7068 N push at 0.9 MPa) is insufficient for your heavy loads, but step down if a 125 mm bore (11045 N) provides enough force. An adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering flexibility a fixed-stroke SAI cannot match. For position holding without continuous air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) instead, as the SAIJ adjuster is strictly a travel stop.
This ISO 15552 dimensionally interchangeable cylinder uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options. With a 750 mm stroke, the 40 mm rod and M36x2 thread handle significant side loads, but an external guide is recommended for unsupported lengths to prevent premature seal wear.
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 SAIJ160BX750-50S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of push force and 9425 N of pull force. It reaches a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 750 mm nominal stroke by up to 50 mm, creating a 700-750 mm usable travel window. It functions as an end-position stopper for fine-tuning and requires live air to hold the load.
