About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-100
The AirTAC SAIJ160X240-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a rear adjusting screw that allows you to shorten the effective stroke by up to 100 mm, creating a highly flexible 140-240 mm usable travel window without swapping out the entire actuator. Delivering 18095 N of push force at 0.9 MPa, this bore size handles massive loads with ease. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments, alongside PT tapered port threads. The adjustable stopper acts solely on the retract end to decelerate and set the travel limit; it is not a locking device and will not hold the load without live air pressure. For load-holding requirements without continuous pressure, consider the AirTAC SAIL or BSAI clamp-lock series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-100 Is Used
Heavy Pressing Operations
Provides up to 18095 N of force at 0.9 MPa for heavy pressing, staking, or forming tasks, with the 100 mm rear adjuster allowing precise control over the final bottom-dead-center position.
Variable Product Diverter
Ideal for diverting different sized packages on a conveyor line, where the 140-240 mm travel window can be quickly tuned to match varying box dimensions without changing the cylinder.
Machine Changeover Setup
Enables rapid mechanical reconfiguration of heavy machinery during product family changeovers, using the rear stopper to set new retract limits safely and efficiently.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-100 the Right Cylinder?
Selecting this 160 mm bore makes sense when your application demands extreme thrust that smaller bores cannot provide, such as stepping up from a 125 mm bore that only yields 11045 N at 0.9 MPa. The 100 mm adjustment range is particularly valuable during machine commissioning or product changeovers, allowing operators to dial in the exact end-stop mechanically rather than adding external physical stops. When replacing an existing ISO 15552 cylinder, verify the 160 mm bore, 240 mm nominal stroke, 100 mm adjuster, PT port thread, and standard mounting interface to ensure a drop-in fit.
Because the nominal stroke of 240 mm is substantial, the heavy piston rod and moving mass should be supported by an external guide to prevent excessive side-loading on the rod seals. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR variants found on some other series. Note that this model does not include a magnet for sensors; if position detection is needed, a non-contact external sensor or a different SKU with the -S option would be required.
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 SAIJ160BX240-100 FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. The maximum theoretical force at 1.0 MPa is 2050 kgf.
The rear adjuster screw allows you to mechanically shorten the 240 mm nominal stroke by up to 100 mm, providing a usable travel window of 140 to 240 mm. This stopper only sets the end position and deceleration; it does not lock or hold the load without live air pressure.
