Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50
The AirTAC SAIJ160X150-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing with 14074N and pulling with 9425N at 0.7 MPa. The built-in rear stopper allows you to trim the nominal 150 mm stroke back by up to 50 mm, creating a precise 100-150 mm usable travel window without needing external stops. This feature is ideal for dialing in exact end positions during machine commissioning.
Built with a robust 40 mm carbon steel rod and an M36x2 thread, this extruded aluminum profile cylinder handles substantial side loads, though long strokes still require external guiding. It features PT tapered port threads (G3/4) and variable air cushions at both ends to decelerate heavy payloads. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50 Is Used
Product Size Changeovers
Quickly alter the effective stroke from 150 mm down to 100 mm to accommodate different package sizes on a packaging line without swapping out the entire actuator.
Heavy Press Tuning
Fine-tune the exact bottom-out position of a high-force pressing operation during commissioning, ensuring perfect contact without adding external mechanical shims.
Adjustable End Stops
Set precise retract end-positions on heavy material handling equipment, using the rear screw to dial in the exact 100-150 mm travel window required for the process.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-50 the Right Cylinder?
Selecting this 160 mm bore model makes sense when your application requires the immense power of a larger cylinder but still needs fine-tuning at the end of travel. If you need slightly less force, stepping down to the 125 mm bore yields 8590N push at 0.7 MPa, while moving up to the 200 mm bore provides 21991N. Choose the SAIJ adjustable-stroke version over the fixed SAI cylinder when you anticipate product changeovers or need to compensate for mechanical tolerances during setup. To match this ISO 15552 replacement exactly, specify the 150 mm stroke, 50 mm adjustment range, PT port threads, and your preferred mounting option from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (note that FB, CA, CB, and CR mounts are omitted).

- ✓ 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 SAIJ160X150-50 FAQ
The cylinder has a nominal 150 mm stroke, but the external rear adjusting screw allows you to shorten the effective travel by up to 50 mm. This creates a usable travel window of 100-150 mm, letting you fine-tune the retract end position at commissioning without changing the actuator itself.
At an operating pressure of 0.7 MPa, the SAIJ160X150-50 delivers a push (extend) force of 14074N and a pull (retract) force of 9425N. It can achieve a maximum push force of 18095N at 0.9 MPa.
