About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-75
The AirTAC SAIJ160X280-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy-duty automation. It yields 14074N of push force at 0.7 MPa, making it well suited to high-load positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and the standard PT G3/4 port ensures high airflow for rapid cycling.
This specific SKU features a 75mm adjustment range, creating a usable travel window between 205 and 280mm. You can fine-tune the retract end-position at commissioning without adding external stops. The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and the cylinder operates at speeds of 30-500mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-75 Is Used
Product Size Changeover
Quickly reconfigure the retract distance on packaging lines running different carton sizes by dialing the 75mm adjuster instead of replacing hardware.
Heavy Press Tuning
Precisely set the forming depth on heavy-duty presses during initial commissioning, using the 205-280mm travel window to dial in the exact contact point.
Variable End-Stop Positioning
Adapt automated assembly stations to different part heights on the fly, relying on the 14074N push force to handle substantial payloads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-75 the Right Cylinder?
Select this 160mm bore cylinder when an application demands heavy thrust that a 100mm bore cannot provide, or when stepping down from a 200mm bore to reduce physical size and air consumption. The 75mm rear adjuster is ideal for production lines running mixed product sizes, allowing operators to dial in the exact end-stop during changeovers rather than physically swapping cylinders. For any fixed-position requirement, the standard SAI series is a simpler alternative.
When specifying this replacement, match the 280mm stroke, 75mm adjustment code, PT G3/4 port, and your required mounting accessory. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR brackets. Because the total stroke reaches 280mm, an external guide should be used to support the load and prevent excessive side-loading on the 40mm rod. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure, so a SAIL or BSAI lock cylinder is required for dead-end holding.
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 SAIJ160BX280-75 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 13230N of pull force. It can achieve a maximum push force of 18095N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the nominal 280mm stroke by up to 75mm, providing an effective travel range of 205 to 280mm. It allows you to fine-tune the end position without swapping the cylinder, but it does not lock the load without continuous air pressure.
