About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-30
The AirTAC SAIJ160X750-30 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to dial back the nominal 750 mm stroke by up to 30 mm. This creates a precise 720-750 mm usable travel window, enabling exact end-position tuning at commissioning without swapping the barrel or adding external stopper blocks. Driven by a robust 40 mm SUS304 stainless steel rod, it delivers 14074 N of thrust at 0.7 MPa.
Because the stroke extends to 750 mm, the 40 mm rod and M36x2 thread provide substantial rigidity, yet an external guide remains critical to prevent side-load binding on long unsupported travels. The extruded aluminum barrel includes sensor grooves on both sides for mounting position switches, while the PT tapered port threads ensure a tight, reliable pneumatic connection under high pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-30 Is Used
Heavy Press Tuning
Dial in the exact 720-750 mm retract distance during machine commissioning to accommodate varying material thicknesses without installing physical shims.
Product Changeover
Adjust the end-stop on the fly when switching the production line to a new pallet size, saving minutes of manual reconfiguration per shift.
Long-Stroke Forming
Leverage the 14074 N of thrust at 0.7 MPa for deep-draw forming operations, using the rear screw to limit travel and prevent over-stroking the tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-30 the Right Cylinder?
Select this 160 mm bore when your application requires heavy thrust in the 10053 to 14074 N range (at 0.5 to 0.7 MPa) combined with variable end-stop positioning. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N. The adjustable stroke is ideal for product-size changeovers on a line, allowing operators to fine-tune the retract distance on the fly.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 750 mm nominal stroke, 30 mm adjustment range, PT port threads, and SUS304 (B) rod material. Note that this SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead.

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 SAIJ160BX750-30 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective travel from the 750 mm nominal stroke down to a minimum of 720 mm. This provides a 30 mm tuning window for exact end-position setting without replacing the cylinder.
At a standard 0.5 MPa operating pressure, it generates 10053 N of push force and 9425 N of pull force. When operating at 0.7 MPa, the push force increases to 14074 N.
