About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-10S
The AirTAC SAIJ160X155-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the travel end during commissioning. With a nominal 155 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 145-155 mm to perfectly dial in end positions without adding external stops. This robust 160 mm bore generates 18095 N of push force at 0.9 MPa, making it suited for heavy-duty positioning.
This variant features a carbon steel rod and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and because this is a -S model, it includes a magnet ready for AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to set deceleration and end-position; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-10S Is Used
Heavy Press Tuning
Dial in the exact 145-155 mm travel window during heavy press commissioning to accommodate material thickness variations without swapping the cylinder.
Assembly Line Changeover
Quickly adjust the rear stop for end-position tuning when switching between product sizes on a high-force assembly line.
Variable End-Stop Forming
Set precise deceleration and end positions for large metal-forming operations where a fixed stroke would require external stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-10S the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust, delivering 14074 N of push force at 0.7 MPa. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N at the same pressure, while maintaining the same ISO 15552 mounting interface. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, whereas a fixed-stroke SAI cylinder is better for dedicated, single-purpose tasks. Remember that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live pressure, consider an AirTAC SAIL or BSAI cylinder instead of relying on the adjuster. To replace this cylinder, match the 160 mm bore, 155 mm stroke, 10 mm adjust, PT ports, and the -S magnet.
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 SAIJ160X155-10S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 9425 N of pull force. Its maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 155 mm nominal stroke by up to 10 mm, creating a 145-155 mm usable travel window. This stopper sets the end position and deceleration but does not lock or hold the load without continuous air pressure.
