About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-40
The AirTAC SAIJ160X900-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down from a 900 mm nominal stroke to a 860 mm minimum. Delivering a robust 18095N push force at 0.9 MPa, this 160 mm bore actuator handles heavy-duty positioning with ease. The extruded aluminum barrel integrates sensor grooves on both sides for flexible switch mounting.
This specific SKU utilizes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. It features a PT tapered port thread and operates at speeds of 30-500 mm/s. The rear adjustment screw acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-40 Is Used
Heavy Fixture Positioning
Provides the 18095N push force required to shift heavy machining fixtures, while the 860-900 mm window allows exact alignment during initial commissioning.
Product Line Changeover
When a production line switches product sizes, the 40 mm rear stop adjustment lets operators quickly trim the extend position without disassembling the actuator stack.
Automated Assembly Presses
Uses the SUS420J2 stainless rod to resist shop-floor moisture while applying consistent clamping pressure at variable end-stops within the 900 mm travel limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-40 the Right Cylinder?
Choose this 160 mm bore actuator when a 100 mm bore cylinder lacks the necessary thrust (offering only 7068N push at 0.9 MPa) and you need the 18095N force class to move heavy fixtures. The 40 mm adjustment range is ideal for machine setup and product changeovers, allowing you to dial in the exact end-stop without swapping the cylinder or adding external stops. Because the nominal stroke is 900 mm, an external guide is strongly recommended to prevent excessive side-load on the rod.
For load-holding applications without continuous live air, remember that the SAIJ rear adjuster and air cushions only decelerate the travel end; they do not function as a lock or brake. You would need to specify an SAIL (air-released lock) or BSAI (clamp-lock) cylinder for fail-safe holding. This SAIJ model mounts via Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces, omitting the FB, CA, CB, and CR mounts found on other variants.

- ✓ 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 SAIJ160AX900-40 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095N of push force and 9425N of pull force. It reaches a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 900 mm nominal stroke by up to 40 mm, creating a usable travel window of 860-900 mm. It only sets the end position and does not lock the load without air pressure.
