About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-75
The AirTAC SAIJ160X650-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 650 mm travel to a precise 575-650 mm window. Delivering massive thrust, it pushes with 14074 N and pulls with 9425 N at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and this specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance.
Because the rear screw acts purely as a mechanical stop to set the end position, it does not lock the load without continuous air pressure. For load-holding without live air, an external rod lock or a SAIL pneumatic lock cylinder is required. The 650 mm stroke on this large-bore unit means an unsupported rod is highly susceptible to deflection, so an external guide rail must be used to prevent excessive side-loading and premature seal wear.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-75 Is Used
Heavy Press Tuning
Fine-tune the 575-650 mm pressing depth on large assemblies without mechanical modifications, ensuring precise end-force application.
Product Changeovers
Quickly adapt a heavy-duty conveyor diverter or stopper arm to accommodate different pallet sizes by dialing the rear adjuster.
Large Fixture Setup
Establish exact clamping reach on automated machining lines during initial commissioning, avoiding the need to machine custom spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-75 the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (5497 N push at 0.7 MPa) lacks the power for heavy presses, but a 200 mm bore (21991 N push at 0.7 MPa) is physically too large. The 75 mm adjustment window is ideal for product changeovers, letting you fine-tune the end position at commissioning without adding external stopper blocks or swapping out the entire cylinder for a fixed-stroke SAI.
When matching ISO 15552 dimensions for a replacement, verify the 160 mm bore, 650 mm stroke, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. Operating speed is 30-500 mm/s.
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 SAIJ160BX650-75 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At 0.5 MPa, the push force is 10053 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 650 mm down to 575 mm. This mechanical stopper fine-tunes the end position but does not hold the load without live air pressure.
