About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-10
The AirTAC SAIJ160X125-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty pneumatics. It features a 160 mm bore generating 10053 N of pull force at 0.5 MPa, alongside a carbon steel piston rod with an M36x2 thread. Utilizing a PT tapered port, this extruded aluminum barrel design ensures reliable operation.
This specific SKU provides a 115-125 mm usable travel window, allowing you to dial back the nominal 125 mm stroke by up to 10 mm during commissioning. The rear adjuster acts purely as a mechanical stop to set the end position and relies on the variable air cushion for deceleration; it does not hold the load without live air. For load-holding requirements without continuous air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-10 Is Used
Heavy Machinery Setup
Fine-tune the 115-125 mm travel window during heavy equipment commissioning to achieve exact end-positioning without external stopper blocks.
Product Line Changeover
Quickly adjust the rear stroke stop by up to 10 mm to accommodate varying product sizes on the assembly line without changing the cylinder.
Deceleration Tuning
Leverage the 50 mm cushion length alongside the mechanical stopper to safely dial in the deceleration of heavy 10053 N loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-10 the Right Cylinder?
Selecting this adjustable-stroke model over a fixed SAI cylinder is ideal when you need precise end-position tuning at machine setup or during product changeovers without swapping hardware. If your application requires less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N. To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 160 mm bore, 125 mm stroke, 10 mm adjustment, PT G3/4 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Although the stroke is under 300 mm, the heavy M36x2 rod still requires external guiding to manage side loads effectively.
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 SAIJ160X125-10 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force at 0.7 MPa. It operates efficiently at speeds between 30-500 mm/s.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from 125 mm down to 115 mm. This creates a 115-125 mm usable travel window for fine-tuning during setup, but it does not lock the load without live air pressure.
