About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-20
The AirTAC SAIJ160X850-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 830-850mm usable travel window. Delivering 10053N of push force at 0.5 MPa, it handles heavy loads while allowing precise end-position tuning during commissioning without external stops. This made-to-order 850mm stroke utilizes a robust 40mm SUS420J2 stainless steel rod (material code A) for high side-load resilience.
Equipped with a G3/4 PT tapered port and 50mm variable air cushions at both ends, it manages kinetic energy effectively within its 30-500mm/s speed range. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU omits the magnet, requiring a field-installed piston magnet to utilize CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-20 Is Used
Heavy Press Tuning
Dial in the exact 830-850mm end position for large pressing assemblies without swapping cylinders or adding mechanical shims.
Product Changeover
Adjust the retraction stop on the fly to accommodate different pallet sizes on a heavy-duty transfer line.
Long-Stroke Positioning
Move substantial jigs along an 850mm path while using the rear screw to perfectly seat the load at the end of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-20 the Right Cylinder?
Choose this 160mm bore when 10053N of thrust at 0.5 MPa is required, or step down to the 125mm bore (6136N) for lighter loads. The 20mm rear adjuster is ideal for fine-tuning the retraction point on product changeovers, functioning strictly as a travel stop rather than a lock. For load-holding without live air pressure, integrate an external rod lock or select an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 160mm bore, 850mm stroke, 20mm adjustment, G3/4 PT port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Because the 850mm stroke is long, an external guide is recommended to prevent rod binding under high side 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 SAIJ160AX850-20 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that trims the effective stroke back by up to 20mm, creating an 830-850mm travel window. It sets the end position but does not lock the load without live air pressure.
