About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-20
The AirTAC SAIJ160X65-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 65mm travel that can be dialed back by up to 20mm, yielding a precise 45-65mm usable stroke window for commissioning flexibility. Belonging to the 160mm bore class, it generates 10053N of pull force at 0.5MPa and up to 18095N at 0.9MPa.
This unit features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at 30-500mm/s and utilizes PT tapered port threads sized G3/4.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-20 Is Used
Press Tonnage Setup
Dial in the exact 45-65mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stops.
Machine Changeover
Rear screw adjustment allows rapid end-position tuning when switching product sizes on a shared high-force assembly line.
Heavy Forming Lines
Provides up to 18095N of push force at 0.9MPa for robust forming operations while permitting fine-tune stroke trimming in the field.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-20 the Right Cylinder?
Choose this 160mm bore when your application requires substantial thrust, such as 14074N push force at 0.7MPa. If your force requirements are lower, stepping down to a 125mm bore yields 6136N at 0.5MPa, whereas moving up to a 200mm bore provides 15708N at 0.5MPa. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the end position without swapping the cylinder or adding external stops.
The rear adjuster functions strictly as a travel stop and deceleration point, not a lock. It will not hold a load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series. The robust 40mm rod and M36x2 thread handle high side loads, but long unsupported strokes still require an external guide. SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.
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 SAIJ160AX65-20 FAQ
At 0.5MPa, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9MPa, the push force increases to 18095N.
The rear adjuster allows you to shorten the 65mm nominal stroke by up to 20mm, creating a 45-65mm usable travel window for precise end-position tuning during setup.
