About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-20
The AirTAC SAIJ160X35-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 35 mm stroke that can be fine-tuned down by up to 20 mm, creating a precise 15-35 mm usable travel window. Belonging to the 160 mm bore class, it generates 10053 N of pull force at 0.5 MPa and accommodates operating speeds of 30-500 mm/s.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop to decelerate the load, not as a locking device; maintaining position requires continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-20 Is Used
Heavy Press Fit Tuning
Dial in the exact 15-35 mm insertion depth for heavy press fits during machine setup, using the rear stopper to perfect the end position without external shims.
Product Changeover
Quickly adjust the travel window on a packaging line to accommodate varying product sizes, relying on the 20 mm trim range for rapid format changes.
High-Force End Stop
Leverage the 10053 N pull force to securely seat heavy industrial components, using the adjustable stop to set the precise retraction limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX35-20 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high thrust combined with exact end-position tuning during commissioning, avoiding the need to swap components for minor travel adjustments. If the 10053 N pull force at 0.5 MPa exceeds your requirements, stepping down to a 125 mm bore yields 5734 N. To replace an ISO 15552 cylinder, match the 35 mm stroke, 20 mm adjustment range, PT G3/4 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). For load-holding without live air, consider an external rod lock or the SAIL series. The robust 40 mm SUS304 rod handles high side loads, but external guiding is recommended for any long unsupported strokes.
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 SAIJ160BX35-20 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force at 0.7 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the 35 mm nominal stroke back by up to 20 mm, resulting in a usable travel window of 15 to 35 mm. It decelerates the load but does not hold it without live air.
