About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-20
The AirTAC SAIJ160X325-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 305-325 mm window. It delivers substantial thrust, providing 14074 N push force at 0.7 MPa and 18095 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning.
This unit uses a SUS304 stainless steel rod and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the retraction end position; it does not lock or hold the load without continuous live air pressure. For load-holding requirements, a SAIL or BSAI series cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-20 Is Used
Heavy Pressing
Provides up to 18095 N of thrust at 0.9 MPa for heavy-duty assembly and forming operations.
Changeover Tuning
Dial in the 305-325 mm retraction end-stop during product size changes without mechanical rebuilds.
Automated Clamping
Secures large workpieces on automated lines, relying on live air to maintain the clamping force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-20 the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore class (offering 5497 N push at 0.7 MPa) is insufficient for heavy pressing or clamping. The adjustable stroke is ideal for machine setup and product changeovers, allowing you to dial in the exact 305-325 mm end-stop without swapping cylinders or adding external stops. Because the stroke is 325 mm, an external guide is recommended to manage side-load risks on the long unsupported rod.
Dimensionally interchangeable per ISO 15552, this model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It operates at speeds of 30-500 mm/s.
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 SAIJ160BX325-20 FAQ
At 0.7 MPa operating pressure, the push force is 14074 N and the pull force is 9425 N. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 325 mm stroke by up to 20 mm, providing an effective travel window of 305-325 mm for fine-tuning at commissioning.
