About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-30S
The AirTAC SAIJ160X65-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, providing 14074N of push force at 0.7 MPa, making it suited for heavy-duty operations. The integrated magnet allows seamless position detection using AirTAC CMSE reed or DMSE electronic solid-state switches.
Featuring a 65 mm nominal stroke, the external rear stopper lets you fine-tune the effective travel down by up to 30 mm, creating a precise 35-65 mm usable window. This cylinder uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-30S Is Used
Heavy Press Fitment
Dial in the exact 35-65 mm insertion depth for large bearings during heavy machinery assembly, allowing on-the-fly tuning without changing hardware.
Product Size Changeover
Adapt a heavy-duty packaging or forming line to new product dimensions by simply turning the rear stopper to shift the end-of-stroke position.
Robotic End Effectors
Provide high-force clamping with precise, adjustable travel limits for large robotic grippers, utilizing the integrated magnet for DMSE sensor feedback.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-30S the Right Cylinder?
Select this 160 mm bore cylinder when an 80 mm bore (providing 3518N push at 0.7 MPa) is insufficient for your load, but a 200 mm bore is physically too large. The adjustable 35-65 mm travel window is ideal for applications requiring exact end-position tuning during commissioning or product changeover, eliminating the need to physically swap out a fixed-stroke SAI cylinder. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
For a complete ISO 15552 interchangeable replacement, match the 160 mm bore, 65 mm stroke, 30 mm adjustment code, PT port thread, and the -S magnet option. Because the 40 mm rod diameter and M36x2 rod thread handle substantial loads, ensure your mounting configuration from the available SAIJ subset properly supports the rod to minimize side-loading, even on this relatively short stroke.
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 SAIJ160AX65-30S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074N of push force and 13195N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 20053N.
The rear adjusting screw acts as an external stopper that trims the 65 mm nominal stroke by up to 30 mm, providing a usable travel window of 35 to 65 mm. It sets the end position but is not a lock, meaning the cylinder requires live air to hold its load.
