About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-40
The AirTAC SAIJ160X155-40 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 155 mm stroke that can be dialed back by up to 40 mm, yielding a usable travel window of 115-155 mm. This built-in adjustability allows precise end-position tuning during commissioning without swapping hardware or adding external stops. Belonging to the 160 mm bore class, it generates 10053 N of push force and 9425 N of pull force at 0.5 MPa.
Equipped with a robust 40 mm carbon steel rod and an M36x2 rod thread, the unit handles substantial side loads, while its 50 mm variable air cushions decelerate heavy masses smoothly. The extruded aluminum barrel features sensor grooves on both sides for CMSE reed or DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-40 Is Used
Heavy Press Tuning
Dial in the exact 115-155 mm contact distance during machine setup to prevent over-travel on heavy pressing operations.
Product Changeover
Quickly adjust the rear stopper to accommodate varying package sizes on a packaging line without changing the cylinder.
Assembly Station Setup
Fine-tune the end-of-stroke position during commissioning to perfectly seat large components without adding external stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-40 the Right Cylinder?
Select this 160 mm bore actuator when an application requires heavy thrust—stepping up from a 125 mm bore roughly doubles the output, moving from 6133 N to 10053 N of push force at 0.5 MPa. Choose the SAIJ adjustable variant over a fixed-stroke SAI when a machine requires variable end-stops or product-size changeovers. The rear screw acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI locking cylinder series.
Because the 155 mm stroke exceeds 300 mm? No, but for any stroke over 300 mm you would need external guiding. At 155 mm, the 40 mm carbon steel rod provides excellent rigidity. To match this ISO 15552 footprint exactly, specify the 160 mm bore, 155 mm stroke, 40 mm adjustment, PT tapered ports, and your required mounting kit.
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 SAIJ160X155-40 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder produces 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it achieves 2050 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 155 mm down to 115 mm. This creates a 115-155 mm adjustable window for fine-tuning the end position without replacing the cylinder.
