About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-75S
The AirTAC SAIJ160X75-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5MPa. Because this specific SKU carries a 75mm adjustment code on a 75mm nominal stroke, it yields a highly versatile 0-75mm usable travel window for exact end-position tuning. The extruded aluminum barrel features sensor grooves on both sides, and this configuration includes a magnet (-S) for use with AirTAC CMSE reed or DMSE electronic solid-state switches.
This model uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjusting screw acts purely as a mechanical stop to trim the retract distance during commissioning; it does not lock or hold the load without live air. For position holding without pneumatic pressure, an external rod lock or related types like the SAIL or BSAI cylinders are required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-75S Is Used
Variable End-Stop Positioning
Ideal for heavy press operations needing precise lower-dead-center tuning, allowing operators to dial in the exact 0-75mm travel distance during setup without external mechanical stops.
Product Changeover Systems
Enables rapid adjustment of retract distances on automated lines handling varying product heights, utilizing the full 75mm trim range to accommodate different part profiles instantly.
Heavy-Duty Clamping Fixtures
Provides reliable clamping thrust up to 10053N at 0.5MPa while permitting micro-adjustments to the final clamping position to compensate for material thickness variations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-75S the Right Cylinder?
Choose this 160mm bore when an application requires substantial thrust, such as 10053N push and 9425N pull at 0.5MPa. If the force requirement is lower, stepping down to a 125mm bore provides 6136N push force, saving physical space. The SAIJ adjustable-stroke design is selected over a fixed-stroke SAI cylinder when a machine requires variable end-stops or fine-tuning during product changeovers without swapping the actuator.
When replacing an ISO 15552 cylinder, match the 160mm bore, 75mm nominal stroke, 75mm adjustment range, PT tapered port threads, and the -S magnet. The mounting interface accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, omitting FB, CA, CB, and CR options. Although the stroke is short, the M36x2 rod thread and 40mm rod diameter provide high structural rigidity, yet external guidance should still be evaluated for heavy lateral loads.
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 SAIJ160AX75-75S FAQ
At 0.5MPa operating pressure, this 160mm bore cylinder generates 10053N of push force and 9425N of pull force. At the maximum 1.0MPa pressure, it achieves a maximum push force equivalent to 2050kgf.
The rear adjuster screw acts as a mechanical stop that allows you to trim the effective stroke back from the 75mm nominal length, providing a 0-75mm usable travel window. It only sets the travel end-point and does not hold the load without continuous live air pressure.
