About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-20
The AirTAC SAIJ160X115-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers a robust 10053N of push force at 0.5 MPa and features a 115mm nominal stroke that can be dialed back by up to 20mm, providing a usable travel window of 95-115mm. This built-in adjustment allows you to fine-tune the retract end position during commissioning without swapping out the cylinder or fabricating external stops.
This bore size features a 40mm carbon steel piston rod with an M36x2 thread, paired with 50mm variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel includes dual sensor grooves for mounting CMSE reed or DMSE electronic switches, though this specific configuration omits the internal magnet. The SAIJ mounting set supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-20 Is Used
Machine Setup Changeover
Dial in the exact retract end position within the 95-115mm window during product size changes on a packaging line, eliminating the need to machine custom spacers.
Heavy Press Positioning
Leverage the 10053N push force at 0.5 MPa to move heavy platens, using the rear stopper to precisely set the final resting position without altering the main pneumatic plumbing.
Variable End-Stop Calibration
Fine-tune the stroke limit during initial commissioning to accommodate sensor flag placement or mechanical clearance variations directly at the cylinder.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-20 the Right Cylinder?
Selecting this 160mm bore is appropriate when your application requires substantial thrust, such as the 10053N push force at 0.5 MPa or 14074N at 0.7 MPa. If your load requirements are lower, stepping down to a 125mm bore yields 6136N at 0.5 MPa, whereas a 200mm bore provides 15708N for heavier demands. The adjustable 95-115mm travel window is highly beneficial for product changeovers on automated lines, allowing precise end-stop tuning without adding external spacers.
For ISO 15552 dimensional interchangeability, ensure you match the 160mm bore, 115mm stroke, 20mm adjustment range, PT tapered port threads, and the specified mounting style. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding without continuous air, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinders instead. Because the rod diameter and M36x2 thread are robust, they handle higher side loads, though any long-stroke setup still requires an external guide to prevent binding.

- ✓ 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 SAIJ160X115-20 FAQ
The rear adjuster acts as a mechanical stop that can shorten the 115mm nominal stroke by up to 20mm, creating a usable travel window of 95-115mm. It allows you to set the exact retract end position during commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N.
