About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-50
The AirTAC SAIJ160X750-50 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 700 to 750 mm, allowing you to dial back the nominal 750 mm stroke by up to 50 mm during commissioning. Delivering 14074 N of push force at 0.7 MPa, it is built for heavy-duty positioning.
This unit uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides. While the rear adjuster sets the retract end-position, it functions purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-50 Is Used
Heavy Press Tuning
Fine-tune the 700-750 mm travel window during machine setup to perfectly seat heavy assemblies without changing out the physical cylinder.
Product Changeover
Adjust the retract stop on the fly to accommodate different package lengths moving down a line, using the 50 mm trim range to set new end positions.
Large Assembly Jigs
Leverage the 14074 N push force at 0.7 MPa to shift heavy pallets, dialing in the exact end-stop location during initial jig commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-50 the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore class (delivering 5497 N push at 0.7 MPa) is insufficient, but you want to avoid stepping up to the massive 200 mm size. The 50 mm adjustment window is perfect for variable end-stops or product changeovers, eliminating the need to physically swap cylinders or bolt on external stops. For load-holding without continuous air pressure, select the SAIL series or an external rod lock.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints. Configuration for this SKU: 160 mm bore, 750 mm stroke, 50 mm adjust, PT port, SUS304 rod, no magnet, and mounting options limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 750 mm, an external guide rail is recommended to prevent excessive side-loading on the rod.
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 SAIJ160BX750-50 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. The maximum operating speed is 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 750 mm down to 700 mm. It only sets the end position and does not lock the load; live air pressure is required to hold position.
