About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-75
The AirTAC SAIJ50X160-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 85-160 mm usable travel window. Delivering 982 N of push thrust at 0.5 MPa, it handles mid-range actuation with precision. The piston rod uses SUS420J2 stainless steel (code A) for improved corrosion resistance, and the extruded aluminum barrel includes sensor grooves on both sides.
The 75 mm adjustment range allows you to fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder. The rear adjuster acts as a travel stop to set the end position, while variable air cushions at both ends manage deceleration. It does not hold the load without live air pressure; for load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-75 Is Used
Machine Changeover
Dial in the retract stroke from 85 to 160 mm during product size transitions without disassembling the actuator assembly.
End-Stop Trimming
Fine-tune the final end position during machine commissioning to avoid adding external mechanical stops.
Variable Positioning
Adjust the travel window on automated lines to accommodate varying material lengths on the fly.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-75 the Right Cylinder?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa and significant on-machine adjustability. If your application requires less force, the 40 mm bore provides 628 N; for higher force, the 63 mm bore offers 1559 N. The 75 mm adjustment range is ideal for prototyping or lines running multiple product sizes, allowing you to dial in the exact end-stop without adding external physical stops. For a fixed end position, the standard SAI series is a simpler alternative.
As a dimensionally interchangeable ISO 15552 cylinder, it replaces units with a 50 mm bore, 160 mm stroke, PT tapered ports, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the 20 mm rod diameter and M16x1.5 thread handle standard side loads, but because the stroke is 160 mm, external guides are recommended if the load is heavy or offset. This SKU does not include a magnet for CMSE or DMSE sensors.
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 SAIJ50 Adjustable Cylinder SAIJ50AX160-75 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push thrust and 825 N of pull thrust. At the maximum pressure of 1.0 MPa, it delivers up to 200 kgf.
The rear adjuster screw lets you shorten the 160 mm nominal stroke by up to 75 mm, creating an 85-160 mm usable travel window. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air.
