About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-40S
The AirTAC SAIJ160X750-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 750 mm stroke with an integrated stopper that allows you to fine-tune the effective travel down to 710 mm. In the 160 mm bore class, this actuator delivers substantial thrust, pushing with 14074 N at 0.7 MPa and reaching 18095 N at 0.9 MPa.
This variant includes a SUS304 stainless steel piston rod for superior corrosion resistance and is equipped with a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the standard PT G3/4 porting ensures high flow capacity for rapid actuation.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-40S Is Used
Heavy Press Tuning
Dial in the exact 710-750 mm end position on a large press during setup, allowing precise product thickness changes without swapping out the actuator.
Large Part Diverter
Adjust the retract stop on a heavy-duty conveyor diverter to accommodate different pallet sizes on the fly, ensuring accurate positioning.
Machine Changeover
Fine-tune the end-of-stroke stop during production line changeovers, saving time by avoiding the need to physically bolt on external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-40S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires 9425 N of pull force at 0.5 MPa, and you need the flexibility to dial in the exact end position during machine commissioning without adding external stops. If your process needs less force, stepping down to the 125 mm bore yields 5734 N of pull force at 0.5 MPa. For load-holding without continuous air pressure, note that this rear adjuster acts only as a travel stop; you would need an SAIL air-released lock or a BSAI clamp-lock cylinder instead.
At a 750 mm stroke, the unsupported piston rod is highly susceptible to side-loading damage; always guide the load externally to prevent rod bending. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Configuration: 160 mm bore, 750 mm stroke, 40 mm adjustment, PT G3/4 port, SUS304 rod, magnet included.

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 SAIJ160BX750-40S FAQ
At 0.7 MPa it provides 14074 N of push force and at 0.9 MPa it provides 18095 N. The maximum theoretical force at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 750 mm nominal stroke down to 710 mm, creating a 710-750 mm usable window. It decelerates the travel end but does not lock or hold the load without live air pressure.
