About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-40S
The AirTAC SAIJ160X185-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 145 to 185 mm, allowing you to dial back the 185 mm nominal stroke by up to 40 mm during commissioning. Belonging to the 160 mm bore class, it generates 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa, making it suited for heavy-duty positioning tasks.
This unit includes a standard carbon steel rod and PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides, and because this SKU includes the -S magnet option, it works directly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear stopper mechanism acts solely as a travel stop to fine-tune the end position, meaning it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-40S Is Used
Heavy Press Tuning
Dial in the exact 145 to 185 mm end-position during heavy press assembly to accommodate material thickness variations without adding external stops.
Product Size Changeover
Quickly adapt automated heavy-duty machinery to different product lengths by adjusting the rear stopper screw up to 40 mm during line changeovers.
Machine Setup Calibration
Fine-tune the end-of-stroke position at machine commissioning to perfect heavy-load indexing, avoiding the need to bolt on secondary physical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-40S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial thrust, such as 10053 N pull at 0.5 MPa, combined with precise end-position tuning. If your process can operate with less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers without swapping the physical cylinder. For load-holding requirements without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. To match this ISO 15552 replacement exactly, specify: 160 mm bore, 185 mm stroke, 40 mm adjustment, PT ports, standard mounting (Basic, FA, LB, TC, FTC, TCM1, TCM2), and the -S magnet option.

- ✓ 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 SAIJ160X185-40S FAQ
This 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force at 0.7 MPa. At 0.9 MPa, it delivers 9425 N of pull and 18095 N of push.
The rear adjuster screw allows you to shorten the 185 mm nominal stroke by up to 40 mm, creating a usable travel window of 145 to 185 mm. This stopper only sets the end position and does not lock or hold the load without live air pressure.
