Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 105mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30
The AirTAC SAIJ160X105-30 is a double-acting ISO 15552 profile cylinder featuring an external rear stroke adjuster. It provides a usable travel window of 75-105 mm, allowing you to dial back the 105 mm nominal stroke by up to 30 mm during commissioning. In this 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa and reaching 18095 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the carbon steel piston rod features an M36x2 thread for robust load coupling.
This adjustable variant lets you fine-tune the retract end-position without swapping hardware or adding external stops. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The rear adjuster acts purely as a travel stop to set deceleration points; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30 Is Used
Machine Setup Tuning
Dial in the exact 75-105 mm retract stop during machine commissioning without machining external spacers or swapping cylinders.
Product Size Changeover
Quickly adjust the end-position by up to 30 mm to accommodate different product lengths running on the same conveyor line.
Heavy Forming End-Stop
Leverage the 18095 N push force at 0.9 MPa for high-thrust pressing tasks while precisely bounding the travel limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-30 the Right Cylinder?
Choose this 160 mm bore when 10053 N of push force at 0.5 MPa is insufficient, or step down to a 125 mm bore if 6136 N adequately covers your workload. The adjustable 30 mm window is ideal for product changeovers on a line where exact end-stops vary, avoiding the need to stock multiple fixed-stroke SAI cylinders. Because the 105 mm stroke is relatively short, side-loading is less severe, but the 40 mm rod diameter still requires an external guide for heavy lateral loads.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 105 mm stroke, PT tapered port, and the standard carbon steel rod. Note that no magnet is specified for this configuration, so CMSE or DMSE sensors cannot be used without a -S variant. Remember that the rear adjuster is a stop, not a lock; use SAIL or BSAI models if your application requires true position holding without live air.
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 SAIJ160X105-30 FAQ
At 0.7 MPa it provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop that shortens the 105 mm stroke by up to 30 mm, creating a usable travel window of 75-105 mm for fine-tuning without moving the cylinder mount.
