About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-75S
The AirTAC SAIJ160X145-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 70 to 145 mm, allowing you to dial back the nominal 145 mm stroke by up to 75 mm during commissioning. Belonging to the 160 mm bore class, it generates 10053 N of push force and 9425 N of pull force at 0.5 MPa. This extruded aluminum body includes sensor grooves on both sides and ships with a -S magnet ready for CMSE reed and DMSE electronic switches.
Equipped with a robust 40 mm carbon steel rod and M36x2 thread, this model handles demanding side loads effectively. It uses G3/4 PT tapered ports and incorporates variable air cushions at both ends to decelerate heavy payloads smoothly across its 30-500 mm/s speed range. The rear adjustment screw sets the retract end position without requiring external stops, though it functions strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-75S Is Used
Product Size Changeovers
Dial in the 70-145 mm travel window instantly on the factory floor to accommodate varying product dimensions without replacing the actuator.
Commissioning End-Tuning
Fine-tune the exact retract position during machine setup using the rear stopper, eliminating the need for custom shims or external stops.
Heavy Payload Positioning
Leverage the 10053 N push force to move heavy assemblies into place, relying on the dual air cushions to absorb kinetic energy at the end of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-75S the Right Cylinder?
Choose this 160 mm bore when an application requires substantial thrust, such as 10053 N at 0.5 MPa, but needs less travel than the 200 mm bore option which offers 15708 N. The 75 mm adjustment range is particularly useful for product size changeovers, enabling operators to reposition the end-stop precisely without swapping the cylinder or adding external mechanical stops. For load-holding requirements without continuous air pressure, this standard SAIJ adjuster is not a lock; consider the SAIL pneumatic lock or BSAI clamp-lock series instead.
When specifying a replacement, ensure it matches the 160 mm bore, 145 mm nominal stroke, 75 mm adjustment range, G3/4 PT port, and -S magnet. The compatible SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Although the 145 mm stroke is below the 300 mm threshold requiring external guides, the heavy 40 mm rod still provides excellent resistance to deflection on shorter strokes.
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 SAIJ160X145-75S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. It can reach a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this SAIJ160X145-75-S, you can trim the 145 mm nominal stroke back by up to 75 mm, creating a usable 70-145 mm positioning window.
