About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-20S
The AirTAC SAIJ160X160-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 140 to 160 mm. Delivering 10053 N of push force at 0.5 MPa, it handles heavy-duty positioning with precision. The included -S magnet enables direct mounting of CMSE reed and DMSE electronic solid-state sensors along the dual-side barrel grooves.
This model features a robust 40 mm carbon steel rod and M36x2 piston thread, paired with 50 mm variable air cushions at both ends to manage high kinetic energy. The rear adjustment screw acts purely as a mechanical stop for fine-tuning end positions during commissioning; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 140-160 mm end-position during heavy press commissioning without swapping out the entire cylinder.
Product Size Changeovers
Quickly adapt the stroke window on automated assembly lines when product dimensions change, minimizing machine downtime.
Variable End-Stop Actuation
Provide adjustable physical stops for heavy-duty ejection or forming operations where the exact travel distance varies between batches.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-20S the Right Cylinder?
Choose this 160 mm bore when a 10053 N push force at 0.5 MPa is required, or step down to the 125 mm bore (6136 N) if your application demands less thrust. An adjustable-stroke cylinder is selected over a fixed SAI model when product changeovers require variable end-stops without physically swapping the barrel or adding external stops. For load-holding without continuous air pressure, this plain SAIJ is insufficient—consider the SAIL air-released lock or BSAI clamp-lock series instead.
This SKU includes PT tapered ports (G3/8) and a standard carbon steel rod. It supports a reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. Operating speed ranges from 30 to 500 mm/s. Because the 160 mm stroke exceeds 300 mm? No, but even at 160 mm, long unsupported strokes should use an external guide to prevent rod side-loading damage.
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 SAIJ160X160-20S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push thrust and 9425 N of pull thrust. At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm, creating a 140 to 160 mm usable travel window. It only sets the end position and does not hold the load without live air pressure.
