About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-40
The AirTAC SAIJ160X750-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 710 to 750 mm usable travel window, allowing you to dial back the end-of-stroke position by up to 40 mm during commissioning without adding external stops. It delivers a robust push force of 14074 N at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This model uses a SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. Variable air cushions at both ends absorb kinetic energy, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-40 Is Used
Heavy Press Fine-Tuning
Dial in the exact end position for a heavy-duty press during setup, using the 40 mm rear adjustment window to compensate for tooling tolerances without external stopper blocks.
Product Size Changeover
Quickly adapt a packaging line to different pallet heights by adjusting the retract stroke within the 710-750 mm range, reducing machine downtime between production runs.
Large Assembly Positioning
Move heavy structural components into place using the 14074 N push force at 0.7 MPa, relying on the built-in air cushions to safely decelerate the 750 mm travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-40 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial thrust, such as the 10053 N push force generated at a lower 0.5 MPa. The 40 mm adjustment range is ideal for fine-tuning machinery during product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If true load-holding is required without continuous air pressure, consider the SAIL or BSAI series instead, as this rear adjuster only sets the travel end.
For a 750 mm stroke, the M36x2 rod thread and 40 mm cushion length help manage deceleration, but the long unsupported stroke necessitates an external guide to prevent excessive side-loading and premature seal wear. To replace an ISO 15552 cylinder, match the 160 mm bore, 750 mm stroke, PT ports, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ160AX750-40 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40 mm. This creates a 710 to 750 mm usable travel window for fine-tuning the end position at commissioning.
At an operating pressure of 0.7 MPa, the SAIJ160X750-40 generates a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
