About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-20
The AirTAC SAIJ160X155-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty tasks. At 0.9 MPa it generates 18095 N of push force and 9425 N of pull force at 0.5 MPa. The built-in rear stopper screw allows you to fine-tune the effective travel down to a 135-155 mm window, providing precise end-position control without adding external stops.
This 160 mm bore utilizes a G3/4 port and a robust 40 mm carbon steel rod with an M36x2 thread, ensuring high structural rigidity under heavy loads. It features variable air cushions at both ends with a 50 mm cushion stroke to absorb kinetic energy, while the extruded aluminum barrel includes dual-side sensor grooves for mounting CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-20 Is Used
Heavy Press Tuning
Dial in the exact 135-155 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Line Changeover
Rapidly adjust the retract end-position by up to 20 mm when switching machinery to assemble a new, slightly shorter product variant.
Large Material Clamping
Leverage the 18095 N push force at 0.9 MPa to securely clamp large workpieces while using the rear screw to fine-tune the final clamping position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-20 the Right Cylinder?
Select this 160 mm bore when your application requires extreme force that exceeds the 11045 N push limit of the 125 mm variant at 0.9 MPa. The adjustable 20 mm stroke window is highly advantageous during machine commissioning or product changeovers, letting you dial in the exact 135-155 mm end-stop mechanically rather than swapping out a fixed-stroke SAI cylinder.
For replacement matching, verify the 155 mm stroke, 20 mm adjustment range, PT tapered port threads, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 40 mm rod and M36x2 thread handle substantial side loads, ensure your external guide rails support the payload, as the rear adjuster acts strictly as a travel stop and air cushioning handles deceleration, not load holding. For dead-stop positioning without live air pressure, consider an external pilot-operated check valve or the AirTAC SAIL lock series.
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 SAIJ160X155-20 FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 14074 N. At 0.5 MPa, it delivers 10053 N push and 9425 N pull.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 155 mm nominal stroke by up to 20 mm, creating a usable travel window of 135 to 155 mm. It is a travel stop for end-position tuning, not a lock, and cannot hold the load without continuous air pressure.
