About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-100S
The AirTAC SAIJ160X750-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers massive thrust, pushing with 14074N and pulling with 9425N at 0.7 MPa. The integrated -100 adjustment mechanism allows you to trim the nominal 750 mm stroke back by up to 100 mm, creating a 650 to 750 mm usable travel window for precise end-position tuning during commissioning.
This unit features a SUS304 stainless steel piston rod for superior corrosion resistance and ships with PT tapered ports. Because it carries the -S magnet option, it directly supports AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side barrel grooves. The rear adjuster acts strictly as a travel stop to fine-tune deceleration, not as a lock, meaning live air pressure is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-100S Is Used
Large Press Damping
Fine-tune the 650-750 mm travel window on heavy press equipment to precisely dial in the end-of-stroke stopping position without external stopper blocks.
Pallet Positioning
Adjust the rear stopper on the fly during product-size changeovers to set new end positions for large pallets without changing the cylinder.
Heavy Material Handling
Leverage the 14074N push force at 0.7 MPa to move heavy materials, using the SUS304 rod for corrosion resistance in demanding industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-100S the Right Cylinder?
Choose this 160 mm bore when your application requires higher force than the 125 mm class (8590N push at 0.7 MPa) but less than the 200 mm class (21991N). The adjustable rear stopper is ideal for machine setups requiring variable end-stops or product-size changeovers without physically swapping the cylinder or adding external stops. For load-holding without continuous air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead, as the SAIJ adjuster cannot hold loads unpowered.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 750 mm stroke, 100 mm adjustment range, PT port thread, and -S magnet. The approved SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 750 mm stroke is long and unsupported, an external guide is mandatory to prevent side-load damage to the rod and seals.

- ✓ 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 SAIJ160BX750-100S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. At its maximum rated pressure of 1.0 MPa, it achieves a push force of 18095N.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 750 mm by up to 100 mm, providing a usable travel window of 650 to 750 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
