Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75S
The AirTAC SAIJ160X900-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 900 mm travel to a precise 825-900 mm window during commissioning. Delivering 14074 N of push force at 0.7 MPa, it is built for heavy-duty positioning. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for position feedback.
This unit uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, paired with PT tapered port threads. The rear adjustment screw acts purely as a travel stop to fine-tune the retract end position without adding external stops. It supports a speed range of 30-500 mm/s and utilizes variable air cushions at both ends to decelerate the massive load over its 50 mm cushion length.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75S Is Used
Heavy Press Positioning
Fine-tune the 825-900 mm travel window during machine setup to precisely strike heavy assemblies without remounting the actuator.
Variable End-Stop Setup
Dial in the retract position by up to 75 mm during product changeovers, using the rear screw to adapt the end-stop to new part sizes.
Large Assembly Line
Leverage the 14074 N push force at 0.7 MPa to move heavy pallets, using the 50 mm air cushions to safely decelerate the load.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75S the Right Cylinder?
Choose this 160 mm bore when a 125 mm bore (providing 8590 N push at 0.5 MPa) is insufficient for your heavy loads, but a 200 mm bore is oversized. The 75 mm adjustment range is ideal for product changeovers, allowing you to shorten the stroke by up to 75 mm without physically swapping the cylinder. Because the rear adjuster and air cushions only decelerate the travel end, this plain SAIJ cylinder cannot hold a load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 900 mm stroke, 75 mm adjustment, PT G3/4 ports, and the -S magnet. Given the 900 mm stroke exceeds standard compact lengths, the 40 mm rod diameter carries significant side-load risks; always use an external guide to prevent rod bending. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ160AX900-75S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 900 mm down to 825 mm. It allows fine-tuning of the end position during commissioning but does not lock or hold the load without live air pressure.
