Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-100
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 155mm 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 SAIJ160X155-100
The AirTAC SAIJ160X155-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 55 to 155 mm without adding external stops. In the 160 mm bore class, it delivers substantial thrust, providing 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the -S magnet.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm air cushions at both ends to manage heavy kinetic energy. Because the rear adjuster acts strictly as a travel stop to set deceleration endpoints, it will not hold a load without live air pressure; for true load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-100 Is Used
Machine Changeover
Dial in the 55-155 mm travel window during product size transitions to set new end positions without physically swapping the cylinder.
Heavy Pressing
Leverage the 14074 N push force at 0.7 MPa for heavy pressing or holding operations, tuning the final contact point precisely.
Commissioning Tuning
Fine-tune the retract end position during initial machine setup to perfect timing and mechanical alignment without external stoppers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-100 the Right Cylinder?
Choose this 160 mm bore when you need heavy force capacity that exceeds the 100 mm bore class (which provides 5497 N push at 0.5 MPa), but do not require the extreme 15708 N thrust of the 200 mm version at 0.5 MPa. The adjustable stroke is highly advantageous during commissioning or product changeover, allowing you to dial in the exact end position on the fly rather than machining custom spacers or swapping a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 155 mm nominal stroke, 100 mm adjustment range, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 155 mm, side-load risks are minimal, but long unsupported loads should still use an external guide. For position holding without live air, an external rod lock or pilot-operated check valve is required.
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 SAIJ160X155-100 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. At 0.5 MPa, it provides 10053 N of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the 155 mm nominal length, creating a usable travel window of 55 to 155 mm. It functions as a mechanical stop and does not lock the load.
