About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-40
The AirTAC SAIJ160X180-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to fine-tune the stroke. With a nominal 180mm travel and a 40mm adjustment range, you can dial the effective extension back to a precise 140mm window at commissioning without adding external stops. It delivers substantial thrust, offering 14074N push force at 0.7 MPa, making it suitable for heavy-duty positioning.
This 160mm bore model uses a robust 40mm carbon steel rod with an M36x2 thread, which handles high side loads well, though long moves still require external guiding. It features variable air cushions at both ends to decelerate the massive moving mass, but remember the rear adjuster is strictly a travel stop, not a lock. For applications requiring true load-holding without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-40 Is Used
Heavy Press Tuning
Dial in the exact 140-180mm end-stop during heavy press commissioning to accommodate varying material thicknesses without swapping out the entire actuator.
Product Changeover
Rapidly adjust the rear stopper on a packaging line to handle different pallet or product sizes, saving downtime associated with repositioning fixed stops.
Assembly Positioning
Leverage the 10053N pull force at 0.5 MPa to shift heavy assemblies into place, using the 40mm adjustment to fine-tune the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-40 the Right Cylinder?
Choose this SAIJ160X180-40 when your setup requires exact end-position tuning within a 140-180mm travel window. The adjustable rear stopper is ideal for product changeovers on heavy machinery. If you need less force, stepping down to a 125mm bore yields 8590N push at 0.5 MPa, whereas moving up to a 200mm bore provides 21991N at 0.7 MPa. This cylinder uses a PT G3/4 port, supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, and omits FB, CA, CB, and CR brackets.
Because the total stroke is under 300mm, side-load stress is manageable, but the 40mm rod still demands proper external guiding for optimal seal longevity. If your application requires position sensing, you would specify the -S magnet option to use AirTAC CMSE reed or DMSE electronic sensors in the dual-side barrel grooves.

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 SAIJ160X180-40 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. At the maximum operating pressure of 1.0 MPa, it achieves up to 18095N of push force.
The rear external screw acts as a mechanical stop, allowing you to shorten the 180mm nominal stroke by up to 40mm. This creates a usable travel window of 140-180mm for precise end-position tuning. It only sets the travel end and does not lock the load without live air.
