About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX60-20
The AirTAC SAIJ160X60-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 40 to 60 mm. Equipped with a 40 mm SUS420J2 stainless steel rod and PT tapered G3/4 ports, it delivers massive thrust up to 18095 N at 0.9 MPa, making it ideal for heavy-duty pressing and clamping.
This adjustable model uses an external stopper screw to fine-tune the retract end position at commissioning without adding external stops. It includes adjustable air cushions at both ends (50 mm cushion length) and features dual-sided sensor grooves, though position sensing requires adding a magnet.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX60-20 Is Used
Heavy-Duty Pressing
Dial in the exact 40-60 mm travel window during setup to ensure precise pressing force without over-traveling the 40 mm rod.
Product Changeover
Quickly adjust the end-stop by up to 20 mm on the fly to accommodate new workpiece sizes without changing the cylinder.
Machine Setup
Fine-tune the retract position during initial commissioning to align heavy fixtures perfectly using the rear stopper screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX60-20 the Right Cylinder?
Choose this 160 mm bore when 100 mm bore cylinders (providing 7068 N at 0.5 MPa) lack the necessary force for heavy loads. The 20 mm adjustment window is perfect for product changeovers, allowing you to dial in the exact end-stop without swapping the cylinder. The 40 mm SUS420J2 rod handles high side loads, but because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 160 mm bore, 60 mm stroke, PT G3/4 ports, and the reduced SAIJ mounting 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 SAIJ160AX60-20 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 14074 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 60 mm nominal stroke by up to 20 mm, resulting in a usable travel window of 40 to 60 mm.
