About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX500-75
The AirTAC SAIJ160X500-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that trims the effective travel window to 425-500 mm. Built with an extruded aluminum barrel, it delivers heavy-duty thrust, pushing 14074 N at 0.7 MPa. The PT-threaded G3/4 ports and M36x2 rod thread ensure robust pneumatic connections for high-flow operations.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. The rear stopper allows precise end-position tuning during commissioning without external stops. Note that the adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX500-75 Is Used
Heavy Machinery Changeover
Dial in the 425-500 mm stroke window during product size changes on large presses without swapping the cylinder.
Long-Stroke Positioning
Fine-tune the retract end-stop on 500 mm strokes to perfect material push-off distances at commissioning.
Assembly Station Setup
Adjust the end position precisely for heavy fixtures, leveraging 14074 N of thrust at 0.7 MPa.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX500-75 the Right Cylinder?
Select this 160 mm bore when a 100 mm bore (5497 N push at 0.7 MPa) lacks the power for heavy moving masses, but a 200 mm bore is physically oversized. The 75 mm adjustment range is ideal for machinery processing varying product lengths, allowing rapid changeovers. For load-holding without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
Because the 500 mm stroke is substantial, the 40 mm rod diameter requires external guiding to prevent excessive side-loading. It is dimensionally interchangeable with ISO 15552 cylinders. Replacement requires matching bore, stroke, 75 mm adjustment, PT ports, and mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAIJ160AX500-75 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 500 mm nominal stroke by up to 75 mm. This creates a usable travel window of 425-500 mm for fine-tuning without adding external stops.
