About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-40
The AirTAC SAIJ160X150-40 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 14074N push force at 0.7 MPa. It features a 160mm bore, a 150mm nominal stroke, and a PT tapered G3/4 port. By turning the external rear stopper screw, you can trim the effective travel back by up to 40mm, creating a precise 110-150mm usable stroke window for exact end-position tuning.
This heavy-duty actuator uses a 40mm carbon steel piston rod with an M36x2 thread, providing high rigidity against side loads, though long unsupported strokes still require an external guide. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors if a magnet is later required. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-40 Is Used
Press Fit Tuning
Fine-tune the 110-150mm retract stop during press commissioning to achieve exact insertion depths without machining new hard stops.
Assembly Line Changeover
Dial in the stroke up to 40mm when switching between product variants on an automated assembly line, ensuring precise positioning.
Variable End-Stop Setup
Use the rear adjuster screw to set precise end positions for heavy material handling tasks requiring 14074N of push force at 0.7 MPa.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-40 the Right Cylinder?
Choose this 160mm bore when you need substantial power—its 14074N push force at 0.7 MPa easily outclasses the 63mm bore's 2182N. If you require even more force, stepping up to the 200mm bore yields 21991N at the same pressure. The SAIJ160X150-40 is ideal for machine setups needing variable end stops during product changeovers, allowing you to fine-tune the retract position without swapping cylinders or adding external stops.
Because the 150mm stroke exceeds the 300mm threshold? No, but even at 150mm, the 40mm carbon steel rod provides excellent rigidity against deflection. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold the load without live air. For true load-holding without pressure, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552, with PT ports and the specified mounting set.
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 SAIJ160X150-40 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear stopper screw allows you to shorten the 150mm nominal stroke by up to 40mm, creating an adjustable 110-150mm travel window. This mechanical stop only sets the end position and does not lock the load without live air pressure.
