About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-100
The AirTAC SAIJ160X750-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel down from 750 mm to a 650-750 mm window. This built-in adjustability enables precise end-position calibration at commissioning or during product changeovers without swapping out the entire actuator or adding external stops. It delivers massive thrust, pushing 18095 N at 0.9 MPa, making it ideal for heavy-duty operations.
Equipped with a robust 40 mm SUS420J2 stainless steel rod and an M36x2 thread, this unit handles substantial side loads, though its 750 mm length still necessitates an external guide for maximum stability. The barrel is extruded aluminum with sensor grooves on both sides. Note that the rear adjuster acts purely as a mechanical stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-100 Is Used
Heavy Pressing Calibration
Dial in the exact 650-750 mm travel for large assembly presses, allowing fine-tuning of the end position to accommodate different tooling heights during product changeovers.
Variable Length Cutoff
Set precise retract distances on large-scale material cutoff machines, adjusting the stopper on the fly for varying product lengths without changing the actuator.
Heavy Conveyor Positioning
Use the massive 18095 N push force to index heavy pallets, relying on the rear adjuster to perfectly tune the stopping point for different pallet sizes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-100 the Right Cylinder?
Choose this 160 mm bore when the 125 mm class (offering 11045 N push at 0.9 MPa) is insufficient for your heavy-load requirements. The adjustable stroke is highly advantageous for machine setups requiring variable end stops, allowing you to dial in the exact 650-750 mm travel distance on the fly instead of committing to a fixed-stroke SAI cylinder.
For an ISO 15552 replacement match, ensure you specify the 160 mm bore, 750 mm stroke, 100 mm adjustment range, PT G3/4 port, and SUS420J2 (A) rod material. Because this is a 750 mm stroke, long unsupported travel demands an external guide rail to prevent rod bending under side loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options. If your application requires true load-holding without continuous air pressure, this cylinder's adjuster will not act as a brake; you should pivot to the SAIL (air-released lock) or BSAI (clamp-lock) series.

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 SAIJ160AX750-100 FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. It can deliver a maximum push force of 10053 N at 0.5 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 750 mm nominal stroke by up to 100 mm, creating a usable travel window of 650-750 mm. It sets the deceleration end-point but does not lock or hold the load without live air pressure.
