About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-40
The AirTAC SAIJ160X350-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 310-350 mm, allowing you to dial back the 350 mm nominal stroke by up to 40 mm during machine commissioning without adding external stops. Belonging to the 160 mm bore class, it delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and carries a PT tapered G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts purely as a travel stop to fine-tune end positions; it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-40 Is Used
Heavy Press Tuning
Dial in the exact 310 to 350 mm press depth during heavy assembly operations without swapping out the entire cylinder body.
Bending Calibration
Adjust the rear stopper on the fly to fine-tune material bending angles across different metal thicknesses on a single line.
Product Changeover
Quickly reconfigure the end-stop position for varying large-scale product dimensions during automated machinery setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-40 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires 18095 N of push force at 0.9 MPa. If you need less force, stepping down to a 100 mm bore yields 7068 N at 0.9 MPa, while jumping to a 200 mm bore provides 28274 N. The adjustable stroke is ideal for product changeovers where exact end-position tuning varies, saving the cost of swapping a fixed-stroke SAI cylinder.
When ordering an ISO 15552 replacement, match the 160 mm bore, 350 mm stroke, 40 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. Because the stroke is 350 mm, the M36x2 threaded rod and large piston demand an external guide to prevent side-load damage on long unsupported travels. For load-holding without live air, select a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ160BX350-40 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of push force and 16940 N of pull force. At 0.5 MPa, it delivers 10053 N push and 9425 N pull.
The rear adjuster screw allows you to shorten the effective travel from 350 mm down to 310 mm. It acts as a mechanical stop to fine-tune the retract position at commissioning, but it does not hold the load without live air pressure.
