About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-40S
The AirTAC SAIJ160X85-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 45-85 mm, letting you dial back the 85 mm nominal stroke by up to 40 mm during commissioning. This size delivers a robust 9425 N pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This SKU includes a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and features a magnetic piston for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It uses a PT tapered G3/4 port and offers variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-40S Is Used
Machine Setup & Changeover
Dial in the exact 45-85 mm retract distance during product changeovers without swapping the physical cylinder or repositioning hard stops.
Heavy-Duty Forming
Leverage the 14074 N push force at 0.7 MPa to press or form components, using the rear adjuster to precisely set the tooling end-position.
Variable End-Stop Positioning
Adjust the effective stroke on the fly to accommodate minor variations in incoming material thickness or width on heavy automation lines.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-40S the Right Cylinder?
Choose this 160 mm bore when you need high thrust—10053 N push at 0.5 MPa—and the flexibility to fine-tune the retract end-position without adding external stops. If your application requires less force, stepping down to a 125 mm bore yields 6136 N push at 0.5 MPa. The rear adjuster on this SAIJ acts purely as a travel stop to set the 45-85 mm window; it does not hold the load without live air. For true fail-safe load holding, select an AirTAC SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 85 mm stroke, 40 mm adjustment range, PT G3/4 port, and the -S magnet requirement. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR brackets. Although the stroke is short, the 40 mm diameter rod and M36x2 thread handle high side loads, but always guide the load externally to prevent rod binding.

- ✓ 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 SAIJ160AX85-40S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 85 mm nominal stroke by up to 40 mm. This creates a usable travel window of 45-85 mm, enabling fine-tuning of the end position without replacing the cylinder.
