About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-50S
The AirTAC SAIJ160X145-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic sensors. By incorporating a 50mm adjustment mechanism, this unit provides a usable travel window of 95-145mm, allowing operators to dial in the exact retract position without swapping hardware.
This bore features a robust 40mm carbon steel rod and a PT tapered G3/4 port to handle high flow demands. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It is important to note that the rear adjuster acts strictly as a travel stop for end-position tuning, not a lock, and the cylinder requires live air to maintain its load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-50S Is Used
Heavy Press Tuning
Dial in the exact 95-145mm end-stop during heavy press commissioning to accommodate material thickness variations without machining new spacers.
Product Changeover
Quickly adjust the retract position on packaging lines when switching to different pallet sizes, leveraging the 50mm trim range for rapid format resets.
Sensor Calibration
Utilize the integrated -S magnet with DMSE solid-state sensors to confirm the adjusted end position, ensuring precise signal feedback for automated sequences.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-50S the Right Cylinder?
Choose this 160mm bore when an application demands substantial thrust, stepping up from a 125mm bore that provides 6136N at 0.5 MPa. The adjustable 95-145mm travel window is ideal for machine setups requiring frequent product changeovers, replacing the need for fixed-stroke SAI cylinders when exact end positions must be fine-tuned on the fly. Although the 40mm rod handles significant side loads, any stroke of 145mm should still be guided by external rails for optimal longevity.
For a direct ISO 15552 replacement match, verify the 160mm bore, 145mm nominal stroke, 50mm adjustment range, PT G3/4 port, and the -S magnet option. If the machinery requires true load-holding without continuous air pressure, a standard SAIJ is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ160X145-50S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder generates 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the 145mm nominal stroke, providing a usable travel window of 95-145mm. It allows fine-tuning of the retract end position during setup but does not lock the load without live air pressure.
